ComboFix is an Anti-Malware tool used by advanced malware technicians specifically trained in its use.

Please DO NOT USE COMBOFIX on your own without supervision!!!

We ask that you obey the warnings about using this tool. Why? The warnings are given for a reason and one of them is to inform our members about the consequences that may occur when using ComboFix in an unsupervised environment. Yes, ComboFix is an excellent but powerful tool. I liken it to Acetaminophen (Tylenol). Used correctly, the drug will help with your aches and pains. Used incorrectly, it can destroy your liver and eventually kill you. The same scenario applies to ComboFix. Used in untrained hands this tool can disable your computer and in some cases can make it unbootable. Further, trained helpers prefer to see preliminary scans from other tools like DDS and GMER before asking anyone to run Combofix because they provide comprehensive logs with specific details about files, folders and registry keys which may have been modified by malware infection. Analysis of those logs allows checking for the presence of rootkits, planning an strategy for effective disinfection and a determination if using ComboFix is necessary.

I did the preceeding two steps and I am absolutely cured.

Whenever a system has been compromised by a backdoor payload, it is impossible to know if or how much the backdoor has been used to affect your system...There are only a few ways to return a compromised system to a confident security configuration. These include:
• Reimaging the system
• Restoring the entire system using a full system backup from before the backdoor infection
• Reformatting and reinstalling the system

The only way to clean a compromised system is to flatten and rebuild. That’s right. If you have a system that has been completely compromised, the only thing you can do is to flatten the system (reformat the system disk) and rebuild it from scratch (reinstall Windows and your applications).
