buy apple, thats best antivirus 

yea u right

no system is immune from viruses or malware.  

re anti virus for windows 7.  just get microsoft security essentials.  it's free and it has worked for me :-)

microsoft security essentials is the best I've used. Has a low ram imprint compared to most AV. Also running firefox with noscript installed is a good security measure

It's true, Microsoft Security Essentials is a great option, and free! Talk about +EV. 

Interesting fact, I believe it was 2011, there was a major test of antivirus applications including all the big and small contenders. The best performance was actually Norton I believe, but it only caught 31% of all the threats! Due to this, many see anti-virus programs as a 'mental blanket'. Also, in reality the best way to stay safe is simply to avoid the 'dark corners of the internet'. :)

anti virus = waste of time and money for most people who know their way around the internet.
