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 TenXW

1Kaspersky

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

It is the best ever

2avast!

It's free and there's until now I never had a problem with it! It's a good anti-virus! And it's pretty fast!

It is the best antivirus software ever. Detects virus and deletes viruses but never slows down my computer.

It offers the most protection than any free anti-virus product out there. Plus, it's effective! Should be no. 1 in the free category.

It is the best anti virus in the world

3Symantec (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.

Norton I like you

4AVG

- 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

It's very helpful.

5ESET

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.

Simply the best

6McAfee

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

I had a problem and a bloke from them showed me how to fix it right away. Brilliant customer service with happy employees

7Microsoft 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. - JoshUK

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...

It's very good

8BitDefender

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

It's been like a good software

The Contenders

11F-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 be in this order:
1. F-Secure Internet Security
2. Avira Pro (I have it at home now and it works good so far)
3. Symantec Norton AV
4. ESET NOD
5. F-Secure Antivirus
6. Microsoft Security
7. Pretty much anything but Kaspersky

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...

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 in the very very high or even the 100 % category. Their products scan with two individual engines (bitdefender and f-secure) which guarantee a high detection rate. It also has a lot of good extras, like the software module to delete tracking cookies. And 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.

12Malwarebytes' Anti Malware

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.

Best software for detecting real new threats quickly

13Trend Micro

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

First anti virus I'm using is Norton, then ESET, then AVG, the Kaspersky and the last one is Trend Micro. I'm paying for all the ant-virus, except AVG and using each off anti-virus at least more than a year. Now, I'm stick to Trend Micro because it can detect the virus that Norton and Kaspersky cannot do.

14ZoneAlarm

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.

It is the best free anti-virus I've ever seen

15eScan

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!

This product should be in the top 5. I have been using this product for more than 5 years and had never faced any problem. Earlier I used to use Norton and it was a resource hog unlike eScan which did not slow down my pc. Also the interface is very simple and easy to use. I would recommend this product and give it a 5 Star rating for its performance.

Escan is the best for Smb and Corporate users

17Quick 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.

18Avast Software

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%

FREE AND EFFECTIVE. It's saved my computer many times. Highly recommended.

I think it is the most wonderful antivirus. More version of the antivirus should come into market.

It saved our GYM system!

19Comodo

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!

Most complete, high-quality protection for the price of free.

20Guardian AntiVirus

I have been using it and its working like a F1 race car. I didn't have to worry about the updates as it has a self update feature and it doesn't slow the computer at all. I would highly recommend this.

Tish Anti-Virus is very good working & File Repair capability Available

It's the best anti virus. I have been using for 5 years.
Its protection and price both are perfect for pc.
Another good feature is its cooperative customer support.
I like it very much
