    My girlfriend is unable to use firefox, internet explorer, and Google Chrome. They say the server cannot be found. The only things that do work are Skype and Aim. Other programs that don't work are: Teamviewer, Camfrog, Windows Messenger, and Yahoo Messenger. She has a Dell laptop running Vista 64-bit SP2. This just started out of the blue. Keep in mind there are several users. One of them, being her older brother, goes on bad websites. She has Mcafee 2010 and it seems to be working fine. I'm pretty sure its a virus, but she wants me to be sure. If the virus was obtained from a different user can the other users files be infected? I know viruses can attach themselves to files but can it affect her files and her sisters?
