A virus attacked my computer and completely overtook it. I can not get into safe mode because the arrow keys won't work after I press F8 and then it just goes into windows. I tried taking out the infected drive and attempted to install XP on the other drive (it has 2 drives), but that would not work either. I swapped drives (as I want the bigger drive to be the main drive), but now it won't recognize by DVD player. When I try to run anti-virus, it won't let me. Another anti-virus claiming to be Windows pops up, runs a scan, and then wants money. Also a porn site pops up.
