Last night I tried to watch a video clip, but got a message that I need a certian CODEC. I then clicked on the link provided for the CODEC, and now my PC are constantly giving me a pop-up message that my PC is infected and wants me to download some anti-spyware program. It also constantly resets my home page to "about: blank". Can someone help me to get rid of it? At this stage I cannot give more info, because I am at work and it is my home PC that is infected. Any help will be appreciated.
