My current version of Avast! is 5.0.677
Engine and definitions:110202-1 (02/02/2011 14:50:57)
I have run a Quick Scan, Full Scan and a Boot Scan.
The boot scan picked up 5 instances of PUP:Win32:Mirc-Z which I moved to chest.
My problem is that when I open Firefox to my many homepages an extra site opens up and brings itself to the front, the address starts:
http://91.216.122.161 This site pretends to look like something official from windows, it has the IE logo as a FavIcon, and the page looks like windows explorer of a computer similar to mine, except the drives had the wrong letters and names. It was suggesting that my computer had suspicious applications running and it could fix them, it was also trying to download an .exe . I couldn't close the page and had to kill Firefox from the task manager. If I open Chrome or IE it doesn't open this page. Do you require any other information? What should I do?
