Which is the best anti-virus you have used till now?

You don't need to buy one. Avast, AVG and Avira all do free versions which are perfectly satisfactory. I use Avast myself and it is very effective in protecting me from malicious stuff.

I don't have an antivirus (well, I don't identify my microsoft security essentials an antivirus in my laptop) I suggest you Avast or Avira. They are the most suggested here in our school. They have a good protection also. Maybe they are also free that's why its the one suggested at our school (Did not check them if they're free).

I used AVG anti-virus.

I used to use Norton because I had a terrible virus on my laptop which wrapped itself around files and was extremely hard to get rid of. My regular McAfee wouldn't even touch it. The McAffee tech even advised me to getG Norton. Now I have AVG free anti-virus and a couple of other things that get rid of temp files, history and such.

AVG has certainly taken care of me where anti-virus is concerned. I do have an additional spyware program downloaded too though.

I am using Kaspersky anti virus in my desktop and laptop, so far its working so good and did not encounter any problem. The good thing about this anti virus he can detect any malicious doc or virus even without opening the file.

hi, i actually used eset nod 32 at home,and that is really good because aside from downloadable it can also update it through internet or online,i have always used this since last two years because its also free and easy to use and install.

Hi friend, I used many anti-virus programs (AVG, Avaira, Kaspersky, Norton...) The kespersky is better than others but I didn't use it because when I install it to my computer then it works too slowly So I used avaira and it good. hey friend I don't know about this but my friend said that the anti-virus program that comes with Windows 7 is better than all of that anti-virus programs.

I suggest you Quick Heal Total Security because Quick Heal Total Security is the best anti-virus, not only because it detects every Virus and malware it is because Quick Heal Total Security Anti-Virus detect and clean only Virus and malware where some of Anti-Virus delete some clean files. Choose Quick Heal also if you don't have high specs laptop but if you have at least minimum Intel i3 Processor then you may also choose Bit Defender Anti Virus because, it was slow down my PC when i was using this in low spec (2 GB RAM and Core 2 Duo Processor). So better go for Quick Heal Total Security.

dont buy Avast anti virus is really nice one it may freely available in internet it is coming up to 2038 if u want i will give u siteeee by just updating it is very effective antivirus in my point of view

Hi! I have a netbook with a low capacity, it only has 1 GB of RAM and an Intel atom 1.66 Ghz Processor and i know its a kind of a slow computer that runs windows 7 ultimate but avast anti-virus worked for me, its protection offer is good, even to slow computer like mine. I just want to answer your question but as far as recommendation is concerned I say Avast.

The most important software everyone want to install in a new laptop or pc is an anti virus. Well I suggest you Kaspersky antivirus & AVG antivirus. These two are the best for saving your computer from offline & online viruses.

I found Microsoft Security Essential as best antivirus. It don't use lot of space from your memory. It can only be installed register microsoft Operating System. And it's work really good.You don't have to update it manually it will updated automatically. I hope if you try this you will enjoye it's working.

I use the free version of Comodo which seems to be quite a good all rounder in one package. It has firewall, anti-virus, and malware detection. I also use the paid version of Malwarebytes for extra protection.

Currently I am stay with ESET Smart Security with this they check Network, Web and E-Mail from phising or suspect activity. In the past I ever try Avast, Avira, Norton, Kaspersky.

Even though I have used anti-viruses like Norton and Kaspersky, I felt Kaspersky is best. The reason why I liked is that even if we somehow opened the folder containing any virus, Kaspersky will delete that virus at that very instant itself. The problem with Norton I felt is that we have to run the virus scan every time to detect those and also it requires frequent database updation.

I think Kaspersky is a good one try it. Its Kaspersky Internet Security. I am sure you will be satisfied with it. I will say go for it. It will give your system a all round security.

I use AVG 2013 now, avira is good also but the best is AVG 2013

use Symantec Pro. it is worth the price and lasts a lifetime. very light on the memory usage too. stops ALL viruses even hackers attacks on your IP address. lifetime free updates beats all deals out there. never had any problems since I installed this on my system and its been 6 years already.
