From my experience 3-4years the best free anvirus for me is Avira antivir free edition.

Check http://www.av-comparatives.org/ I prefer Avira Personal, however i heard that Avast isn`t as bad as it`s previous version.

avast is best, and I observed that when the system is affected with Virus..it does not connect to Avast website for update.
Update fails, that time you can do boot scanning it helps.

try norton 2011 beta, if you go for any free antivirus you will not get the full features or you will get it for very limited period...

i use a licenced antivirus, but ithink at first its avira.

and 2nd its avast..............

Wrong

Free try avast and for paid kaspersky

Avast has benn running on my pc for over a year now. I uninstalled Kaspersky and switched to Avast in which I became more satisfied. Avast performs well, and it can even scan your whole computer just before it loads the OS, and it had removed the troublesome "Project1" virus in my PC. Also, the USBVAULT + autorun.inf files stopped returning to the flash drives.

Avast free can't really protect your computer from virus completely. i'd recommend using avg free cause it gives better protection for your computer than avast.

I have been really happy after using the Avast antivirus. By updating it regularly, I think that the best option to use is Avast antivirus.

I think avast is good free antivirus. Its ranking are very good.

Avira is the best.

Try Avast, it is free and they offer 2-3 daily updates. I'm using it for more than 2 years without any problems.

My vote goes to Antivir Avira.

I have using Norton home edition anti-virus. Its validity is 90 days. This very nice antivitus.

To my own point of view, i feel that norton and avira antivirus are the best options. I have used Norton on my laptop for sometime and it has not recieved any virus at all. So, use norton and you will find out that it is a trusted antivirus.

norton, avira, avg..i have used all these..these r good..

I'm on Avira because it's free. I've used AVG and it's okay too. Both are free.

Finally, a member that suggested KasperSky. I prefer the paid version, but the free version is fine.

I would have to suggest AVG, KasperSky and Avast.

Don't use McAfee. The paid version is great but the free version only causes problems, unfortunately...
