I have a dup.exe file that is considered a virus by some anti-malware programs. It is digitally signed by Taiwan Shui Mu Chih Ching Technology Ltd and was with win zipper. I removed this particular program from the program files using the conventional uninstall method but it keeps flashing on my screen with Comodo Anti-V/firewall so it has obviously left some data on my PC that is hard to remove. I have tried several free programs to remove dup.exe but it still persists. It's driving me nuts! If anyone knows of a simple free (I'm unemployed) removal program I can download or they can send me I will be a very happy and relieved man.

@Simba: I found a version of dup.exe signed by "Taiwan Shui Mu Chih Ching Technology Limited" here:

I think FreeFixer should be able to remove that file. You can give it a try. FreeFixer is freeware.

Do you know where I can download that WinZipper tool you mentioned? I'd like to test it myself to see what changes it does to the computer.
