I got a Trojan horse downloader in my msconfig.exe file. How do fix the problem?

KILL or DELETE Answer

01 Try to find this malfunctioned msconfig.exe (usually in c:\win or something like it)

02 DELETE it.

03 Take your original Win CD's and make an copy from those CD;s (msconfig.exe)

04 If you don't have these CD's you can download those progamms from the internet. (Windows/Microsoft?)
