I got bombed by viruses and finally got most of the infected files out. I'm still showing problems in Regedit.exe, winhlp32.exe, and posix.exe. I am also unable to remove many of the programs the viruses infected. Can someone tell me if there is a way to remove this or replace the files that are damaged. I've tried bitdefenders removal tool, spybot(which got infected and will not allow me to remove it), ad-aware, AVG, and a few other things I can't recall. I have my Windows 2000 install disc that came with my computer, but I dont have a serial number. The guy at the computer store I bought from said that it was with the other paper work and he didnt have a copy of it. So I'm afraid to reinstall because I think I need that. I'd appreciate any ideas on how to remedy these issues. Thank you.
