After months as a beta product, Microsoft has now publicly unveiled its impressive free anti-virus software, dubbed "Microsoft Security Essentials".
You can download the appropriate version for your computer from here… http://www.microsoft.com/security_essentials/default.aspx
MSSE uses very little RAM, so it’s ideal for netbooks, laptops and less-powerful desktop PCs.
It automatically updates itself, Microsoft says it will always be free, and it passes the "parent test" — you could tell your mom or dad where to get it and in a few simple clicks, it’ll install, scan, and proceed to run quietly in the background.
Don’t expect to find it loaded on a new PC, though, because makers of paid anti-virus programs pay them to install trial versions of their products!
You can read reviews of MSSE here…

I’ve been using MSSE on all my computers since the first beta version came out almost a year ago, and I’m very happy with it.
