To remove Windows Necessary Firewall virus i had come across through a website http://www.fixspywarenow.com/2011/05/28 ... tructions/
I ran the tool 2 iexplore http://www.thelivetech.com/speedpc to remove the virus. The scan completed very quickly. I could not notice what happend. I am not really sure whether the scan really happend or not. After a fraction of secound the entire page vanished and my system returned to its home page and now it does not allow me to browse any thing and install. what should I do now.
