I'm using another computer (not the old that was infected, or the new one that may be) to send this message. I have the old, infected one with me, but I can't even bring up IE, let alone connect to the internet. If I try to open IE using a user account with administrative privileges (the one I ran malwarebytes on), I get the message in the title of the first post. If I try to open it up using an account with limited privileges, it doesn't recognize the file/program and asks me to identify the program to use to open it. The computer is really messed up. I think the infected files that I removed must have been critical to the computer's operation. I'm considering re-installing XP. I think I can back up the important files before doing this, but I don't know if they are infected. I really don't know what to do about the new computer that may be infected as well. I'm hoping that it won't crash before I can get home, and that maybe I'll no more then than I do now. I didn't think that something like this could get past a reputable antivirus program (AVG), but clearly it can.
