I believe I am infected with malware, and need help removing it. I'm running a XP Acer. I was exploring the net on firefox, and my computer automatically restarted. A pop up from windows fire wall said that it needed to block "spyware.ISpyNow," as I have never used ISpyNow, I realized it must be a virus. Windows claimed it took snapshots of my computer and stole financial info. I Attempted to get online but firefox gave me a infection warning. Thinking this to be a deception I tried to go around, but mozilla crashed. after a few tries, it began to crash immediately on start up. I switched users on this PC to use IE. Both IE and Mozilla run now, but my links are redirected. Additionally the text on many windows differs unusually in size, or runs of the page without resizing. I received another pop up from "anti-virus-pro-scan.com" asking to scan/install on my computer. I have ignored the pop up because I fear it will install either way. Avast has not found anything, I brought my removable hard drive, in case the driver on this computer had been infected, but have have not yet found anything.
