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

I have done beta testing on anti-virus suites for years.

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

I tested Kaspersky, Norton, Webroot, ESET, McAfee and G-DATA.

I tested 200 different malicious files.

Kaspersky detected 198 of those files with zero false positives.

Norton detected 198 of those files with zero false positives.

Webroot detected 195 with zero false positives.

(I'm only showing results from the top three. )

Real-Time Protection:

I went to infected websites and downloaded infected files, pictures, etc.

Out of 35:

Kaspersky detected 35.
Norton detected 33.
Webroot detected 35.

So, the best anti-virus is:

1. Kaspersky
2. Norton
3. Webroot

Powerful! And easy to use, Fantastic Parental control and other features

its obvious that the kaspersky the world's number 1 antivirus for me it is the best among the best antivirus bongatious so if I were you please choose kaspersky because kapersky and me knows the best

Kaspersky is absolutely one of the excellent antivirus product in the market. Protection is always top, and has great removal capability of malware from infected machines. System Watcher is monitoring system changes, roll-back unauthorized modifications if the system has compromised.

2 Symantec (Norton)

IT is the best antivirus in the present in the market everyone should try it because it keeps your pc in the best form

I've been using this for years and its still amazing! I've also tried Kaspersky and Norton is a lot better

Yes I like norton the best antivirus ever as I am using it since 1995,

It is the only antivirus that give removal tool for specific virus.

I had Norton since 1989 and never had a problem with them. One time I got a virus that I couldn't get off my computer so I called Norton and told them and they send me in the mail a disc that got the virus off my computer and they did it for free all I had to do was send the disc back and upload the file that had the virus in it to Norton after my computer was clean. Thank you Norton.

3 ESET

ESET is the best antivirus yet, it is very fast, it don't slow down your system unlike norton and kaspersky.

I had norton before, it almost crashed my system despite the fact that my PC has good specs(2.1GHz duo core HP Pavilion dv6)
Am now using ESET now, it's amazing with daily updates to keep your system protected, since I've had it, I don't know what a computer virus is, believe me, I can comfortably surf the internet without no threat, even visit sites with high virus alert with no system intrusion because I have ESET.

It's the best user friendly antivirus available, very easy to operate and schedule your scans, system inspection and others things.

I can't see myself giving up my ESET to have another antivirus, one can't condescend from the best to something lower, ESET is the best by a mile, believe me

I use ESET because I was tired of other av programs that sucked the power out of my operating system. I love their products and use them in every computer I own.

Most successful Slovak company. Daily updates automatically are convenient and keep computer safe from new threats. Have not had one malware/viral breach in the 8 months I've had it. Has worked better and more subtly so than Norton or McAfee.

I think it is best because not impact to my systems so much. Besides, it protects overall and focus on main function.

4 AVG

- Has caught all viruses so far :)
- Good heuristic protection (both generic and behavioural - Identity Protection)
- Anti-Rootkit module
- Offline virus DBs to download - a BIG plus from my point of view
- Last but not ;east, it's TRULLY free (no catches, unlike other "free" AVs out there)

I used norton and kaspersky but they were too heavy. AVG solved all my problems silently.

just great great antivirus... what a brain they have to make such a antivirus... the programming is real good... and it cleans every bit of viruses

I've used several other anti-virus 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 anti-virus). AVG Business Ed. Is simple, light, and awesome. The fact that they have a free personal edition is icing on the cake.

5 Microsoft Security Essentials

Free, and I've been running it since day one. It's really a fantastic piece of software, and I haven't so much as had a virus since I started using it.

Free & easily handle to use this anti-virus... 100% my system is working properly...

MSE is the best and also free. The only remark is it heats up the pc while you are scanning your pc...

Runs nice and quiet in the background with minimal CPU resource usage... Just the way I like it. Have tried Kaspersky, Avast, AVG, and Norton, and of those I thought Avast was the most decent, but in the end all of them got to me with their paranoid attitude towards viruses and I kicked them all out. Have never looked back. MSE obviously doesn't cover everything, but in combination with Malwarebytes' antimalware, it's pretty solid.

Ultimately, your biggest anti-virus is simply your browsing habits. If you browse a lot of questionable sites, you'll have to be more intense on the countermeasures. For me MSE does the trick, but in the rare case of an actual infection, I also recommend Combofix, a great little piece of software.

6 McAfee

Solved problems with malware and trogans that webroot avg and Symantec (Norton) could not. Norton is not worth the price, three anti virus failed identified the problem could not remove. Mc Afee installed updated on first scan identified Trojans and malware removed them all. Can be pricey software but worth the money if all else fails. If I start using windows again (using Linux). I will get Mc Afee (normally get a year free with bank accounts) and see how good it is again. But linux has no need for AV + virues and trogans in exe form don't install only on VM software (on linux) which can be deleted total because the root can't be infected. No need to scan that can take hours with a deep scan with Tb of data.

it is the best and it has things that can also tell you from first that which of the sites are infected. and the main thing is that it does not slow down your pc at all. none of the antivirus are as good as it is

Mcafee is a light weight yet powerful antivirus. it is protecting my laptop for almost a year. Kaspersky slows the computer down which McAfee doesn't

Mcafee is the best antivirus company. Not necessarily the retail/consumer locked version, but I mean the commercial version that almost every company uses as their vendor now. The commercial version (VSE 8.8 and higher) Is as simple and refined as antivirus gets. It has a perpetual license, it has OAS consistently running when you choose, and everything is just completely customizable. Its like the android of the antivirus/malware world. Once you have the.zip file it can go on an unlimited number of pcs. Its the best antivirus commercially available, its so good I've been able to run it on a crashing pc who's only hope is a reformat and its been able to remove about 90% of issues.

7 BitDefender

In latest tests BitDefender gets the best marks for detection and removal of malicious software and every threat on internet, in AV Test BitDefender has the highest protection marks (better then Kaspersky & Norton), last several years gets the best (Advanced ) marks on AV-Comparatives, many antivirus-test companies clame that BitDefender is the best

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.

The best antivirus, I changed Kaspersy for BitDefender

Scanning a website have 38 viruses Bitdefender, Norton, Kaspersky, Avg, Avast
Bitdefender found 38 (2013 Version
Norton found 38
Kaspersky found 37
Avg found 36
Avast Found 37
Scanning my computer with Norton, Bitdefender, Kaspersky
Bitdefender Secured my pc
Norton up to a certain extent(IT SLOWS YOUR PC DOWN)
Kaspersky also did good but not to my expectations(GREAT ANTIVIRUS WITH LOTS OF MONEY WASTAGE)
BEST ANTIVIRUS IS NO DOUBT BITDEFENDER

8 Avira

THIS SHOULD BE NO.1
powerful German made antivirus
super fast updates and powerful scanning... active webguard

Realy good antivirus program. Install and forget it. Superlight and strong defender.

Avira gives Complete protection. I am using it for last 2 year and its awesome. I highly recommend this.

I am using it for last 4 year and it simple and active
Good heuristic protection, not too heavy. Don't slow down your system unlike others, Offline virus VDF files to download, It's free and I never had a problem with it. I had Norton before it giving heavy load to my system. Try and take a Complete protection against virus.

9 Avast Software

Avast is best virus detection. A total antivirus Solution.This is a good antivirus.

Best security that I have used. It's fast and efficient and offers loads of services plus offers a secure browser. Should at least be in the top 5. 10/10 stars!

Good mobile antivirus software and best pc antivirus software it.

I used it.

Avast has 7 screens, heuristics, sand box and multiple updates daily. I love this antivirus it has a detection rate of approximately 98% in the' PC security 'review 2013 test (avast vs bitdefender). 500 viruses were used for the test. Bitdefender scored 98.6% - avast 98.2%

10 Quick Heal

Quick Heal must be among the top five.
I had installed this antivirus five months ago and since then, I have forgot about computer viruses and malware. It has its unique DNA scan technology which can detect ANY virus in 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 form anywhere like cyber cafes. It gives your computer total protection against viruses and is light too for your system.

the best indeed! please try this at least once!
This is indeed the best antivirus you would ever have had. Indeed the best

Install this total security antivirus & work without worry about viruses, malware, spyware.

In this list of top ten antivirus, I have tried all the antivirus during different periods. I have had the worst experience with McAfee which could not detect Michelangelo and.cih virus in the past which had entered my system and crashed my hard disk. Even with help of Stellar Data Recovery Lab's assistance, neither vital data in my hard disk could be saved and recovered and neither the hard disk could be of any use thereafter.

Similarly most of the antivirus including free trial versions did not detect dangerous worms and Trojans as also macro virus on my system. I being a computer savvy always fond of accumulating all types of data be it movies, songs,.doc,.xls files etc. Most of my data got deleted on finding a virus in the files. Anti Virus should be such that the viruses only get detected and removed and not the entire valuable data.

This was experienced by me with Kaspersky Anti Virus too, which I placed at No. 1 earlier. Alas it was short lived since it too ...more

The Newcomers

? Cisco Systems

The Contenders

11 ZoneAlarm

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

Zone Alarm hides your computer connection to the internet and thus protects you from seeing all the sites that are trying to send you viruses and junk adds etc. #1 in my opinion.

The best, have used it for years have full package and all works with each other.

Very light, verygood detection rate and removal. No doubt best antivirus please try it. It definitely worth in top 3 position

Super Clean New virus Very Good product

Super anti virus should be at the top

This 1s best antivirus product more than other products. Because fast scanning and fast insulation.

13 Panda Security

Easy to download, update and use.
Very Good performance. Of course, it is Free.

Too good for my laptop, now my life easy, it's light and sharp, thanks panda to make my life easy, I suggest to all, get demo, if you satisfy then buy, panda technical support team also help us.

Thanks to protect my mails, PC performance and boot up the speed.
Internet security is good anti virus.
Firewall is also good hacking tool of Panda.

best anti virus that I used so far... very easy to update it... very fast it download update compared to others...

14 VIPRE Antivirus

Fastest growing company in South Asia Pacific... Having presence in whole India, Bangladesh, Nepal and Sri Lanka

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 switch to Vipre I did a head-to-head comparison with Norton, Vipre found quite a few more problems, which 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.

I've had Vipre fro a year now that is reasonably priced and have no virus or malware but it did let my browsers get hi-jacked three times in two months by gaming people and "speedbit accelerator as well. The program did nothing for me and I had to figure out how to take my settings back that took about 20 minutes of work.

It also never makes a sound when it finds things or is suspicious so it makes me think it's not working most of the time, but it does work and I find it pretty good, but can be made so much better as well.

I have been using Vipre for more that 6 Years, and since switching my clients to Vipre from Symantec, McAfee, Trend Micro, and Panda, our calls due to Viruses and Malware have dropped significantly. The sites we use to visit weekly, now call us monthly. Not sure if I should keep using Vipre. -)

15 Comodo

The best antivirus for those, who isn't mentally challenged or just plain stupid.
Requires knowledge of WHAT you do with your computer.

It's cool defense on your pc

As long as you don't deliberately do something seriously DIRTY with your computer, this COMODO internet security, firewall and anti-virus will be your best protection for LIFE!

I am speaking from experience... And best part is that it is FREE!

Comodo is the Best Antivirus ever. I am using it for past 7 years 3 different PC and I never had any issues of virus or malware. Its the best and its free

16 Trend Micro

I really love Trend Micro, it really helped my PC and it also works for smart phones such as apple and android, I bought the Maximum Security product. Try it out!

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)

This is truly a great antivirus. I have had Notron, McAfee, AVG, and Kasperkey, which are all great but I have had the best defense with Trend Micro. The above does anti virus programs take care your usual Trojans, malware, spyware etc. But if you want every bit of data securely passing through your system I feel Trend Micro is the easiest to use.

very effective and lite, works without problems.
it needed a free version so people could know the name

17 Dr. Web

The only android antivirus application software for it.

Simply the best!

Good antivirus company. But good antivirus and not properly Scan it.

Windows 7 and 8 good working this antivirus. But windows8.1 and windows 10 simply work.

18 Malwarebytes' Anti Malware Malwarebytes Inc. is an American Internet security company with offices in Santa Clara, California, Clearwater, Florida, Tallinn, Estonia and Cork, Ireland. It specializes in protecting home computers, smartphones, and companies. ...read more.

I am, among other things, a retired PC repairman & over the years have used several different anti-virus programs. Most of them either slow my computer down, &/or block internet sites deemed malicious, plus the viruses still sneaked in! I have, now been using "Malwarebytes' Anti Malware, " which is supposedly not an anti-virus program, exclusively for more than three years & have never had a virus/malware problem! Had no firewall either! Over the three years, a couple viruses got in, I just scanned with Malwarebytes & in seconds, the problem was solved! AND "Malwarebytes" stays out of the way!

Why is this not at the top. Out of all of the Anti-Virus software I have used this is by far the best. I'm currently using the paid version of this, which is only $20 for a life-time subscription, in conjunction with MSSE. The real-time protection is amazing, and you don't have to put up with all of the shit that you get with McAfee. The definitions are updated daily and it's by far the fastest Anti-Virus when it comes to scanning your system. I can't compare it to any free Anti-Virus software, but I can tell you from experience that it's better than McAfee, Norton and Kaspersky.

Best anti mal-ware program out there, and its free. It saved my computer on several occasions from ad-ware and spy-ware I would highly recommend it.

I heard that MalwareBytes' Anti-Malware saved someone's computer from 5000 viruses.
I have this and Security Essentials. I used to have AVG and McAfee

19 Smadav

Portable mini antivirus, scan virus, registry and hidden objects, has many tools such Process Manager, System Editor, Win-Force, and Smad-Lock, If your Regedit/Task Manager/MS-Commant/MS-Config has been disabled by Virus, you can force Enabled it with a single click.
Not a Powerful Antivirus but it always comes in handy..

It's very simple, and more options to handle problem

I like this antivirus, simple and nice ^_^

Love it, the very best AV I ever use
Complete database of Virus, worms and trojan horse
Drive defense (FDD, HDD) from autorun
and many more

20 eScan

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 excellent parental control feature and it hels me feel safe when the kids are browsing online or usign 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 the temp files get cleaned up when I restart my computer and everyday is a "fresh" start.

I love eScan, it is the best AntiVirus and will highly recommend for everyone to keep their computer's safe and families safe.

I have been testing various AV software and this is one product that you can configure to your satisfaction and things under the hood. Their tech support is remarkable and for free. Try their free antivirus toolkit which can be run as a standalone application to scan and clean your PC without installing the software. The biggest advantage is that you do not need to uninstall your existing AV software to test eScan. Good Luck!

Best Antivirus software. Better Than Microsoft Security Essentials

Good Services. eScan is a powerful antivirus software company.

21 F-Secure

In my experience the best so far is F-secure Internet Security which is proved to be VERY effective while fighting network threats. Recently it helped to fight a very bad attack. F-Secure is user friendly too. The bad thing - it's pricy. We had Kaspersky before and it slowed our comps way too much. Many times Kaspersky claimed that a virus was found but KAV/KISS (we had both versions) couldn't delete it. We had to use CureIt by Dr. Web on a regular basis to fight the viruses that Kaspersky couldn't. Funny that when CureIt was signaling that some virus was found... Kapsersky had the "revelation moment" to say: "I found a virus! " (I wonder why it didn't see it BEFORE CureIt detected it, duh! ). When we removed Kaspersky the new AV found a lot of threats that Kaspersky didn't see. Now we have NOD at work and it works much better, faster and more efficient than Kaspersky. Our employer can't afford F-Secure so we went for NOD. Anyway, my personal choice of AV soft will ...more

Best anti-virus software ever; I've been using it for many years and it has always worked like it should. The only problem in F-Secure is that it is not known widely enough, and I guess that it is also the reason why it is only the 13th in this list (at this moment).

Having tried both Mac Afee and Norton before we have now switched to F-Secure and have not had a problem since. Dunno how the other programs on this list scores but out of these 3 F-Secure is far beyond...

Tried most of the anti-virus packages and this is the best. Bitdefender and Kaspersky are also very good, but F-Secure gives far less hassle on a day to day basis and picks up the most incoming threats.

22 Outpost

Outpost Security suite and Outpost firewall pro is good antivirus. But Outpost firewall free and outpost security suite free is simply the good antivirus.

I like outpost I think it's way too overhated.

PC security 'review 2019 test (Agnitum Outpost vs windows defender). 100 viruses were used for the test. Windows defender scored 80.4% - Agnitum Outpost 80.5%

Outpost Firewall Pro is best.

23 Defender Pro

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

It has a lot of pros and it prevented us from hacker as a virus went in the anz.

24 Max Secure

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

Marvelous

It is the powerful Antivirus

Max secure is the world number 1 total security

25 Net Protector AntiVirus (NPAV)

This NPAV is the best and last solution of pc. It has muti Scan system and other functions which have not any other antivirus in the world. Because I already use most best anti-virus (kaspersky, quickhill, etc) but the could not give real time protection and slow down pc regularly. Lastly I can find this NPAV which keep my laptop faster than others. Thanks. I think it is the number 1 brand in the world.

It's not using any hardware resources from its system. Because I already use most best anti-virus (trend micro, quickhill, etc) but the could not give real time protection and slow down pc regularly. Lastly I can find this NPAV which keep my desktop faster than others. Thanks. I think it is the number 1 brand in the world.

This antivirus is superior & best in new experiments & operating softwares & also getting a greatest response.

It is the best antivirus I have ever used! The best thing about it is that it doesn't slow down PC unlike other antiviruses like mcaffee plus it blocks all the viruses too
