Top 10 Best Antivirus Software Companies

Good antivirus software is an invaluable tool for keeping your computer, your personal information, and the security of your friends and family safe from hackers, identity thieves, and spammers. The damage a single virus can do is astounding.

Today's viruses have the capability to do everything from sending your personal information like credit card numbers and bank accounts to identity thieves to turning your computer into a slave that will send out spam e-mail messages, attack websites, or do pretty much anything else the virus maker wants it to. And on top of that, viruses are programmed to seek out your contacts and try to infect them as well. Odds are good that if your computer gets infected, everybody in your contacts is going to be receiving an e-mail message or IM that looks to be from you and contains the same virus you got.

A good antivirus program will typically cost a bit, but will be nothing compared to the cost of losing your files and your identity. Below are the top ten best antivirus software companies around.
The Top Ten
1 Kaspersky Kaspersky Lab is a world-renowned cybersecurity firm founded in 1997 and based in Moscow, Russia. The company has become a leading name in global antivirus and endpoint security solutions, serving both individual consumers and enterprises. Kaspersky's software is known for its high-level performance in various independent tests, effectively protecting systems from malware, phishing, ransomware, and other cyber threats.

I have been beta testing antivirus suites for years.

For 2009, I found Kaspersky to be the best AGAIN.

I tested Kaspersky, Norton, Webroot, ESET, McAfee, and G-DATA with 200 different malicious files. Kaspersky and Norton detected 198 of those files with zero false positives, while Webroot detected 195 with zero false positives.

(I am only showing results from the top three.)

Real-time protection:
I visited infected websites and downloaded infected files, pictures, etc.

Out of 35:
Kaspersky detected 35.
Norton detected 33.
Webroot detected 35.

So, the best antivirus is:

1. Kaspersky
2. Norton
3. Webroot

2 Norton Developed by Symantec Corporation, Norton is an industry-leading provider of antivirus and anti-malware software. Headquartered in Mountain View, California, the company boasts a rich history dating back to 1982. It offers a suite of cybersecurity tools including virus scanning, firewall, identity protection services, and more. Norton is often recognized for its ability to provide robust, user-friendly, and comprehensive security solutions.

The only antivirus that shows whether the links are risky or not. Others you can know once you click, but Norton does it before you click (on the search page itself). The same goes for its Android version. It can scan apps on the Google Play Store which you are viewing even before clicking install.

Norton is the best antivirus, and it's from one of the most experienced antivirus companies. It has changed a lot now. It's not heavy on system resources either. Just give it a try, and you won't want to change it for any other antivirus program ever.

3 ESET Originating from Slovakia in 1987, ESET is a prominent antivirus software company. The brand is known for its innovative approach to internet security, offering products such as NOD32 Antivirus System. ESET combines advanced heuristics with generic signatures for the best balance between detection and false positives. Serving both personal and business sectors, it has won numerous industry awards for its efficient detection rates and low system impact.

ESET saved us quickly. I actually enrolled in this site to give ESET some congrats. My wife, unaware of the security I had set up with ESET for years, almost got horribly hacked by a smooth, obviously professional scammer. When I saw her on her computer one morning, she had already let this company charge her credit card and gain entry to her computer to "clear up" a problem.

One quick call to ESET, and they not only told us what to do immediately but also got into our system and checked everything. Nothing but one issue had to be resolved with one company and one credit card. A small thing compared to what could have happened had things not been cleaned quickly. I cannot appreciate ESET enough. Worth every penny spent over the years. Very helpful with some other issues over the years. The entire family, desktops, and laptops now and will always have ESET security systems.

4 Bitdefender Bitdefender is a Romanian cybersecurity and antivirus software company, founded in 2001. The company is renowned for its advanced and reliable security products that offer protection against all major types of online threats. Bitdefenderā€™s security suite includes features like anti-malware, firewall, web protection, and multi-layer ransomware protection. Recognized for its powerful technology and high detection rates, Bitdefender has consistently been a top performer in the industry.

Bitdefender is by far the most effective security suite for Windows on the market. These guys have a leading research team which, in many cases, is the first to identify newly formed malware. Their suites have an excellent, frequent definitions update implementation, coupled with a rock-solid detection engine that consumes little system resources. They also have an excellent firewall and privacy options.

The only good, free option is Microsoft's own Security Essentials. In fact, considering its effectiveness compared to other free alternatives, as well as its light footprint, it is very underrated.

As for others:
- Kaspersky is all-around good, but doesn't offer nearly as much value for the money. Also, their reliability has been waning as of recently.
- Norton is garbage which is plagued by inconsistent performance, as well as stability and software update issues. I've had numerous bad experiences with their products.

5 AVG Technologies AVG Technologies, a subsidiary of Avast since 2016, is a Czech company famous for its antivirus software. Established in 1991, the firm's mission is to simplify, optimize, and secure the internet experience of its customers. AVG's software suite includes features such as virus scanning, email protection, web browsing security, and more. The company's products are particularly well-regarded for their user-friendly interface and effective protection capabilities.

I have used AVG for years. The free version works very well. However, the paid version is worth every penny! Norton and McAfee are both jokes. AVG's free version works much better than their software that you have to pay for.

The paid version is only $39.99 and can be picked up at Walmart and other stores. But if you're looking to protect more than one computer, go to AVG/Grisoft's website for a better deal. Try it! You will not go back to those other companies again, EVER!

I've used several other antivirus programs on this list for personal and corporate use (150 PCs, 14 servers). One was way too heavy, expensive, and had bad habits of not staying updated. Another was heavy, expensive, and didn't work (come to find out it really isn't that good unless you install the whole suite, and we wanted only antivirus).

AVG Business Edition is simple, light, and awesome. The fact that they have a free personal edition is icing on the cake.

6 McAfee McAfee, LLC is a globally recognized American computer security software company founded in 1987. Named after its founder, John McAfee, the company delivers advanced security solutions to consumers, small businesses, and enterprises. McAfee's product range includes antivirus, personal firewall, spam filters, and more. It is reputed for its extensive and reliable security features, providing robust protection against various cyber threats.

I solved problems with malware and trojans that Webroot, AVG, and Symantec (Norton) could not. Norton is not worth the price, as three antiviruses failed to identify and remove the problem. McAfee, on the other hand, installed updates and identified trojans and malware during the first scan, successfully removing them all. While it can be pricey software, it is worth the money if all else fails.

If I start using Windows again (currently using Linux), I will get McAfee (usually receive a year free with bank accounts) and see how good it is once more. However, Linux does not require antivirus software, as viruses and trojans in .exe form do not install except on VM software (on Linux), which can be completely deleted because the root cannot be infected. There is no need to perform scans that can take hours with a deep scan on terabytes of data.

7 Avira Avira Operations GmbH is a German-based cybersecurity company established in 2006. Offering free and premium security software products, Avira has gained popularity for its broad array of solutions that include antivirus protection, privacy tools, and performance enhancers. Renowned for its high detection rate and low system impact, Avira provides a balanced blend of usability and robust security for both individuals and businesses.

It has many components that keep you safe. It also offers a VPN along with the other components to increase protection. If you get a virus, Avira fixes it without needing a technical remote. But if all else fails, its customer service will always help you with the toll-free telephone number. It always receives good grades from the testing labs.

I have been using it for the last 4 years, and it's simple and active. It provides good heuristic protection and is not too heavy. Unlike other antivirus software, it doesn't slow down your system.

You can download offline virus VDF files for free, and I have never had any problems with it. Previously, I had Norton, which heavily burdened my system. Give it a try for complete protection against viruses.

8 Avast Avast Software s.r.o., established in 1988, is a Czech-based multinational cybersecurity software company. Recognized worldwide, Avast offers a variety of security solutions, including antivirus, antispyware, and anti-malware products for different platforms. The company has pioneered the concept of 'freemium' antivirus software, offering robust, real-time protection that combines performance, privacy, and advanced threat detection.

Number 1 antivirus software ever! My PC became full of viruses almost a year ago. I tried Norton, Kaspersky, ESET, and many more, but no hope. They couldn't fix my computer. I thought my PC would be damaged. Finally, I bought Avast! Incredible! I started its first scan, and it detected so many viruses. It began destroying all the viruses, and a few hours later, my PC looked like new! So please buy Avast! Premium antivirus to detect and destroy problems like viruses, malware, spyware, hacking, online threats, CD viruses, and many more.

9 Quick Heal Quick Heal Technologies is an Indian cybersecurity firm founded in 1993. Its primary product range includes antivirus solutions for home and business users. Known for its innovative DNA Scan technology, the company provides comprehensive, real-time protection against advanced cyber threats. Quick Heal is especially popular in Asia and has made significant strides in establishing a global presence with its robust and efficient antivirus solutions.

Quick Heal must be among the top five. I installed this antivirus five months ago, and since then, I have forgotten about computer viruses and malware. It has its unique DNA scan technology, which can detect ANY virus on this earth.

You also get daily automatic updates if you have an internet connection. If not, you can download the update files through its website from anywhere, like cyber cafes. It gives your computer total protection against viruses and is light for your system.

I noticed that Symantec, Norton, and McAfee had some limitations at my workplace. Then I sought the opinions of various people, including those from the IT sector, some colleagues from the IS department, and my nephew. I discussed internet and computer usage with them and ultimately concluded that Quick Heal Total Security was the best and easily available option. I have been using it for the past five years and have not encountered any problems. It not only provides total protection for your computer but also for your cellphone. It is truly good.

You can entrust your system's security concerns to Quick Heal Total Security, which can handle everything, leaving you with no regrets.

10 Trend Micro Trend Micro Incorporated, a multinational cybersecurity company, was established in 1988 in Los Angeles, and is currently headquartered in Tokyo. The company is a global leader in enterprise data security and cybersecurity solutions, with a strong focus on cloud-based protection. Trend Micro's security software is appreciated for its advanced AI learning, robust ransomware protection, and emphasis on IoT security.

I got a new computer for Christmas and installed Trend Micro on it, and I haven't had a virus yet. Trend Micro gives me a pop-up if I go to a page with possible viruses, and I've never had a problem.

My old computer used to get viruses all the time, and as soon as I put Trend Micro on it, I never got any viruses at all. The laptop I typed this on has Trend Micro Titanium.

I have been using it for many years, and I haven't had any problems with viruses or other malware. The best thing is that it runs in the background. It uses so few system resources that you don't encounter any issues with updating and scanning. It's the best product.

11 ZoneAlarm ZoneAlarm is a software company owned by Check Point Software Technologies Ltd., a leading cybersecurity firm based in Israel. Launched in 2000, ZoneAlarm is best known for its firewall software and has expanded its offerings to include antivirus, anti-spyware, and intrusion detection software. Recognized for its advanced firewall and additional layers of identity theft protection, ZoneAlarm provides robust and reliable defense mechanisms for PC users.

One of the best products I have ever used, and I have tried all the rest. ZoneAlarm saved my computer from a heavy virus. I tried Avast, AVG, Norton, Eset, Trend Micro, and they all couldn't cope with the virus. ZoneAlarm locked up my computer, killed the viruses, and restarted it. Top 3 definitely.

I buy the download disk every year, and I have never had a problem. As far as I'm concerned, it's in the top 3. They offer a free version, so try it out. I'm sure you will be happy. It has a great firewall and does not slow down your computer.

12 Webroot Founded in 1997, Webroot Inc. is a Colorado-based private company that provides Internet security for consumers and businesses. Noted for its cloud-based approach, Webroot offers highly efficient antivirus solutions that are light on system resources. The company's cybersecurity software offers real-time threat protection, secure browsing, and identity theft protection, making it a reliable choice for home and business users alike.

Say goodbye to old technology's bloatware. Webroot has a very small and lightweight footprint that uses effective new technology to stop suspicious activities before your system gets infected. The product is always scanning, and definitions are always up-to-date because they are "in the cloud" (stored on the Internet). "Cloud computing" and "SaaS" are more than just the latest industry buzzwords. This is how all antivirus products will operate in the future.

No more scheduled scans, no more downloading virus definitions, no more intrusive hooks into the operating system to slow your system down. Best of all, Webroot runs smart detection processes that don't interrupt users with difficult questions that most users can't answer anyway. Instead, it silently keeps the bad guys out in the first place, preventing infections and system conflicts that users have to deal with after the fact. Isn't this the way the ideal antivirus software should operate? Well, the future is here, the ideal is now real. All that's left is to watch the other companies scramble to emulate Webroot's cloud computing SaaS model. I plan to watch it happen from behind my Webroot firewall. Thank you.

13 K7 Security K7 Computing, commonly known as K7 Security, is an Indian cybersecurity company founded in 1991. It is renowned for its antivirus software suite, which includes features like malware protection, firewall, parental controls, and more. K7 Security is known for its fast scanning capabilities and minimal system performance impact, offering reliable protection for home users and businesses alike.

Very handy, fantastically useful, and capable of a lot of functions other than cleaning malware and viruses! It should be at least in the top 5!

This is the best antivirus product compared to others because of its fast scanning and quick insulation.

The best antivirus ever! It's easy to use with unlimited features. I love this antivirus, and I trust it the most.

14 Panda Panda Security is a Spanish cybersecurity software company founded in 1990. The company offers a broad range of products, including antivirus software, a managed office protection suite, and cybersecurity services. Panda is notable for its Collective Intelligence technology that automatically collects and processes viruses, providing fast and comprehensive threat protection.

You may have seen fast antiviruses, but this is the fastest. It is much faster than Norton, Quick Heal, the latest version of Avast, and Kaspersky. The best part is that it can detect every single virus, and its user interface is the best of all antiviruses. It should definitely be number 1.

But what the hell? I'm seeing it at number 11. Who added an extra 1?

Too good for my laptop! Now my life is easier. It's light and sharp. Thanks, Panda, for making my life easy. I suggest to all, get a demo. If you're satisfied, then buy. Panda's technical support team can also help us.

15 Malwarebytes Founded in 2008, Malwarebytes Inc. is a renowned American cybersecurity company. Initially popular for its Malwarebytes Anti-Malware product, the company has expanded to provide a full suite of security software that combats advanced threats. Malwarebytes is recognized for its proactive approach, using advanced heuristics and behavior-based detection to provide robust protection against both known and emerging malware threats.

I am, among other things, a retired PC repairman. Over the years, I have used several different antivirus programs. Most of them either slow my computer down or block internet sites deemed malicious, and yet the viruses still manage to sneak in! For the past three years, I have been exclusively using "Malwarebytes" Anti-Malware, which is supposedly not an antivirus program. I have never had a virus/malware problem since then! I didn't have a firewall either. Although a couple of viruses managed to get in over the three years, I simply scanned my system with Malwarebytes, and within seconds, the problem was solved! Moreover, "Malwarebytes" stays out of the way!

16 VIPRE Antivirus VIPRE Security is an American-based cybersecurity company that has been in operation since the late 1990s. VIPRE's antivirus product line is praised for its advanced malware detection capabilities and low system performance impact. It provides a full suite of security features, including real-time protection, ransomware protection, and email security, providing a high level of protection without slowing down your system.

I've been using VIPRE for the last 5-6 years in conjunction with Malwarebytes Anti-Malware (only for the last year), and I've never had a problem. I used to use Norton and McAfee before and had problems of all sorts, even though the computer is only really used for gaming or word processing. I also love that VIPRE works all the time but doesn't completely take over your computer and make life incredibly difficult.

When I switched to VIPRE, I did a head-to-head comparison with Norton. VIPRE found quite a few more problems that my other security system had completely missed. Not sure how this is ranked 21st, but it should definitely be in the top 10. It really is a great program.

17 Dr.Web Dr.Web is a Russian-based antivirus software suite developed by Igor Daniloff's company, Doctor Web Ltd, founded in 1992. The suite offers a comprehensive range of security services, including antivirus, anti-spyware, anti-spam, and firewall capabilities. Known for its advanced heuristics and flexible configuration options, Dr.Web provides strong protection against current and emerging threats, making it a reliable choice for both individuals and businesses.

Premium Antivirus by Dr. Web is an award-winning virus scanning and filtering software. It provides reliable, effective, and lightweight protection for my PC.

Web Light is a reliable product that uses the most innovative Dr. Web technologies to protect my Mac from viruses and malware.

Quick or full file system scans, as well as custom scans of user-specified files and folders, are available. The SpIDer Guard monitor scans files. This portable anti-malware tool, based on the Dr. Web engine, can run express scans to find and neutralize threats.

18 Smadav Smadav is an Indonesian antivirus software focused on local virus protection. Founded in 2006, it works primarily as an additional layer of defense, making it compatible with other antivirus solutions. Smadav's distinct selling point is its proficiency in guarding USB flash-disk from viruses and restoring infected files. Its lightweight and simplicity make it a popular choice in areas with limited internet connectivity.

Smadav in the top 10? Wow, that's cool. Be proud to be Indonesian. This antivirus is very good and effective in preventing local and international viruses. It also supports many international antiviruses, so they can work together without any crashes. Nice.

Yes! I love this antivirus because it has very good features that are quite easy to use. It works like a charm alongside my main antivirus. And the best part is, it's free!

Portable mini-antivirus scans viruses, registries, and hidden objects. It has many tools, such as Process Manager, System Editor, Win-Force, and Smad-Lock. If your Regedit, Task Manager, MS-Command, or MS-Config has been disabled by a virus, you can force-enable it with a single click. It's not a powerful antivirus, but it always comes in handy.

19 eScan EScan, a product of MicroWorld Technologies, is a comprehensive antivirus and content security solution designed to protect PCs from a broad range of threats. Founded in 1993 and headquartered in India, eScan is globally recognized for its advanced security solutions. Its software uses sophisticated heuristics algorithms to detect and neutralize even unknown threats, providing robust protection for both home and corporate environments.

I have used eScan for several years. I have never had a single issue, either with detection or with the software slowing down my machine.

I have two kids, and they have eScan ISS on their computers as well. It has an excellent parental control feature, and it helps me feel safe when the kids are browsing online or using the web for their research.

The best part is the privacy feature. I make sure that I leave it on so that the cookies and temporary files get cleaned up when I restart my computer. Every day is a "fresh" start.

I love eScan. It is the best antivirus, and I highly recommend it to everyone to keep their computers safe and their families safe.

20 F-Secure F-Secure Corporation is a Finnish cybersecurity and privacy company founded in 1988. Renowned for its antivirus and computer security solutions, F-Secure provides protection against a wide variety of cyber threats. It is known for its advanced malware detection and minimal system impact, winning numerous awards for its performance. F-Secure's commitment to online security and privacy extends beyond antivirus software, covering a broad spectrum of cyber protection services.

Ok, so I've tested F-Secure for about a month, and I tend to believe that this is one of the best antivirus programs ever. The detection rates are almost always very high or even in the 100% category. Their products scan with two individual engines (Bitdefender and F-Secure), which guarantees a high detection rate. It also has a lot of good extras, like the software module to delete tracking cookies. That is something that many antivirus programs do not offer. I wouldn't probably say it's by far the best (because every antivirus program has pros and cons), but for sure one of the best.

21 Defender Pro Defender Pro is a line of security products owned by Defender Pro LLC, an American software company. Known for its all-in-one security and PC maintenance products, Defender Pro offers solutions that combine antivirus, anti-spyware, and system optimization. Defender Pro software is appreciated for its strong real-time protection, frequent updates, and easy-to-use interface, providing consumers with a comprehensive security solution.

Updated every hour to make sure you are protected from the latest threats.

Simply the best and good antivirus software.

It is great. No problems so far. Easy to use.

22 Sophos Sophos Group plc is a British security software and hardware company founded in 1985. With a focus on providing complete enterprise-grade security solutions, Sophos offers products covering endpoint, network, web, email, and mobile security. Renowned for its innovative Intercept X technology, Sophos has been at the forefront of advanced threat protection, offering powerful, easy-to-use security services for organizations of all sizes.

I have been working with computers before viruses existed and have always used and recommended Sophos to all my clients. I chose it because it is the program that governments, banks, building societies, and insurance companies use.

I have had problems with others, and they have slowed the computers down too much. Additionally, they have sometimes lacked the ability to remove some viruses. If you have a Mac, then there is no need to buy Sophos as it is free.

Very good quality corporate antivirus solution. It has good detection capabilities, high performance, fast scanning speed, and low resource utilization. The antivirus (AV) includes an on-access scanner, an on-demand scanner, and an updater, making it basic in terms of features.

However, these are the essential components needed in an antivirus solution. Additional features like "web shields" or "mail shields" are unnecessary as long as the on-access scanner functions properly.

23 Max Secure Max Secure Software is an Indian cybersecurity company founded in 2002. The company develops products for individuals and businesses, offering solutions that protect against viruses, spyware, and other online threats. Its antivirus software, known for fast scanning and low system impact, provides real-time protection and a proactive approach to security, making Max Secure a trusted name in the realm of cybersecurity.

Previously, my PC was too slow to load anything. Then I installed Max Desktop Security. It first scanned my PC and found some viruses and malware. In a couple of minutes, it solved my PC problem. Also, its antivirus feature is very good, with RAM and ROM maximum virus removal alert, etc.

Awesome experience! Its scanning speed is good, and it improves my mobile performance. I recommend everyone to download the app.

It's the lightest antivirus available at the moment with the best results.

24 Net Protector Net Protector, developed by Biz Secure Labs Pvt. Ltd., is an Indian antivirus software company founded in 1993. Its main product, Net Protector Antivirus, has garnered popularity especially in India, providing a comprehensive defense against various cyber threats. It's known for features such as anti-malware, anti-phishing, and network intrusion prevention, offering full-scale protection for home and business users alike.

It's not using any hardware resources from my system. Because I already use the most effective antivirus software, such as Trend Micro and Quick Heal, they couldn't provide real-time protection and regularly slow down my PC. Lastly, I found NPAV, which keeps my desktop faster than others. Thanks. I believe it is the number one brand in the world.

This NPAV is the best and last solution for PCs. It has a multi-scan system and other functions that other antivirus software does not have. I have already tried using the best antivirus programs like Kaspersky, Quick Heal, etc., but they could not provide real-time protection and regularly slowed down my PC.

Finally, I found NPAV, which keeps my laptop faster than others. Thanks. I believe it is the number 1 brand in the world.

25 Bkav Bkav Corporation is a Vietnamese technology company that was established in 1995. It is known for its antivirus software product, Bkav Pro, which offers protection against viruses, malware, and online threats. With a focus on Internet security, Bkav provides a range of services including network security, data protection, and anti-leakage. Its commitment to research and development has established Bkav as a leading name in the cybersecurity industry in Vietnam and beyond.

Oh yeah, I love the small amount of RAM it requires when processing. It doesn't slow down my PC like Kaspersky does. I've tried many other products, but I finally decided to purchase a BKAV program. It works very smoothly, beautifully, and effectively. (Unlike when I scanned my computer with some other programs, they always said "no virus found" @_@).

Good one! I used to have such a tough virus that made me scan, ghost, and re-ghost many times, but no use. Then I used Bkav, and it amazingly got rid of those viruses in a couple of tens of minutes.
