I got some kind of virus that closes any folder or web browers containing anti virus information.
Any one know how I can install a anti virus program or identify this bug, everything I try is closed by the virus.

Have you tried a online virus scan?
Both these are good
Trend Micro - Free online virus Scan (http://housecall.trendmicro.com/)
Panda ActiveScan – Free online antivirus to combat viruses, spyware and other Internet threats. (http://www.pandasoftware.com/products/ActiveScan.htm)
Oh and what browsers are you using?

If I go to any web page that contains Virus information, the browser closes. That includes online virus scan sites. I use IE 6 and Firefox
