So I wondered if I was having problems with malware, and decided to try searching for virus cleaners online. I used Trend Micro's Housecall and found twelve virus infected files(PE_MTX.A) and two Trojans (can't remember which ones). Among these I found a rundll32.exe that i thought was actually malware and cleaned it out. (Am going to restore it after somebody explained it's actually a vital component) I then downloaded AdAware SE and cleaned out the various spyware and data miners that infested the system. Then I ran System File Checker, and came up with these files that are supposedly corrupted:
Any suggestions as to what I should do without having to reformat and reinstall everything on the computer will be most gratefully accepted.
