Virus protection

I use two programs: AVG and Avast! AVG actually caught a site that tried to download Malware for me, so I suppose it may depend on your settings. As for Avast!, it's more thorough than AVG upon scanning and explaining what's on your computer. I recommend it for heavy-duty protection IF your computer can support it, because it's pretty heavy on the RAM. You can download Avast! from their site here: http://www.avast.com/eng/programs.html Remember to choose the free home version. Also, you might want to think about checking your firewall settings. Personally, I use Comodo, and it's pretty thorough about changes made to your system, so it's both online and offline protection.

try zonalarm security suit or bitdefender. both are the no. 1 antivirus solution abialable in the market.

I use kasperksy anti virus to protect my notebook, until now I never found virus problem at my notebook. but if we use KAV, we must connect to internet every day for update virus datebase.

even if you have a good antivirus program, that is not the only thing you need to be not infected by a virus. you must always update your virus definition. another one is try not to be dumb by downloading attachments and application that you don't know about or virus free. most trojans and worms usually installs themselves together with another applications.
