How to block certain file extensions?

Question

Hi, I'm in the process of killing off a very sneaky slippery bugger of a Root Kit virus.
Virus protection seem to notice and block when it tries to make changes, but when I go to kill the virus, it backs itself up with randomly named ".tmp" files...
I could block those ".tmp" files using process blocker, but every time the ".tmp" files are executed, they are named differently!

I'm wondering... Is there a way to block the file extension ".tmp" from being executed?

Additional Details

I am aware that I cannot just Delete a virus... but If I can stop these tmp files from executing, It will buy me some time while i figure out where these extensions are being called from.
Trust me, I have tried those programs you speak of, and they still cant kill it completely by themselves even in safe mode.

Get a good antivirus like Kaspersky or ESET Nod32 which can work very well with root kits, you cannot just DELETE a torjan or virus, cos if you kill the process it wil come up again.

Also a tmp file, is used by windows and many apps, they dont get executed by any sense, untill unless its an exe.

The reason u see the tmp file because the virus in the background is creating them which u cannot stop on your own.. GET an Antivirus
