Anti-Virus?

What is the best free Anti Virus program that I can download? One that works really well? Or what do you think is the best antivirus program?

Anti-Virus?viruses

I have used AVG Anti Virus, Zone Alarm Firewall, Spy-bot Search and Destroy and Ad Aware both spyware killers for years. They are all free for personal use and I have had no trouble with Viruses Trojans etc. AVG does not slow the system down as much as some other products and Zone Alarm allows a lot of personal configuration unlike the Windows Firewall. They can all be downloaded from the following linkhttp://www.computeractive.co.uk/. On the home page select downloads and then the appropriate category.I also use Windows Defender from the Microsoft site. It is safe to use two anti-spy products but never use more than one A/V as it can cause conflicts. You should run A/V and anti spy weekly. Hope this helps

AVG without a single doubt
u can prefer anything such as McAfee, Norton Antivirus, AVG antivirus, Symantec antivirus just download any of antivirus but first change the setting in that to clean the virus if found
If you are serious about protecting your computer, drop the notion of getting something valuable for free.

No one security app by itself tested better than 75%. However, research shows that several compatible apps working together perform best. On my computer I use Trend Micro, Spy Sweeper and Zone Alarm Security Suite. 95% capture rate.
