First things first. I'm new to this forum so I hope I'm doing things right. I have researched like crazy on this problem and can't find a viable solution yet.

Getting to the point: I have a computer that has been overtaken by a very sophisicated malware piece that literally shuts down programs I try to run. I consider myself very savvy (after all I'm an IT technician), so I have an arsenal of tools at my disposal. The tools I tried to run on this computer include:

Autoruns
HijackThis
Process Explorer
Malwarebytes (it did install initially, but running it is not allowed)
AVG Anti Virus

I even tried renaming the .exe to random names like ARHADFGGHB.EXE for autoruns.exe or 3456edfe.exe for hijackthis.exe and the malware STILL knows I'm trying to run these programs. Also, even doing a google search in IE for "hijackthis" will shut down the browser!

All of the above programs run for a split second then close. Task Manager processes show suspicious processes such as "dllhost.exe" and "rundll32.exe" (which are legit MS processes, but have suspicious behaviors in terms of me killing the processes then they restart themselves). The payload of this malware was "System Security" which I was able to remove with no problems by using Unlocker and deleting the "235346456.exe" files and associated DLLs.

I also ran SDFix in safe mode but it didn't find anything important as these behaviors never ceased.

Normally I would just do a wipe and reinstall of the OS but I'm tired of doing that. I want to brush up my skills on malware removal so ANY advice would be appreciated. I'm truly getting really, really sick of these malware!

Thanks in advance!
