Virus Heat is a new variant of an older infection called "Virusprotect". It is mostly downloaded as a trojan disquised as a video codec and is basically a spy ware removal advertisement that ERRONEOUSLY finds unwanted programs on your computer and attempts to scare you into buying the removal program.

It is not a VIRUS.

Because it was a new variant most anti-spyware programs did not catch it and could not remove it. This is typical as the anti spy ware/malware/virus programs are designed to target specifically KNOWN applications.

The removal application program designers needed time to evaluate and then test the removal diagnoses before sending out the new definitions to their programs. AT this time all the anti spy ware/malware/virus programs have updated and they can all remove the threat from your computer or at the least disable the components (which will leave harmless traces behind).

This is the standard for dealing with these types of threats and it just takes time to design against them unless the cure becomes worse than the illness and no one wishes to have that.

All in all...this is a perfect example of learning proper personal safety proceedures for using the internet...think before you download....research itself goes a long way...when in doubt, don't do it!....and slow down and take the time to read the warnings that are designed into your computer and the programs that are installed.
