Well I was using ZoneAlarm AV, and one day I saw that it's icon was missing, so I tried to run it again with no luck, then I tryed to install other AV BitDefender, that is where I found out that my Firefox couldn't connect to the internet, my Outlook and MSN all work fine, after 10 minutes that I start my computer I just can't surf the web, I guess it has to be a virus, but can't find out which one it is.
If some one had this problem please a little help, I don't want to reinstall my computer yet!!!
