It’s worth repeating a few things here. There is a nasty exploit in the way that WMF images are parsed in Windows. This means that WITHOUT user intervention a system can be remotely exploited and through that exploit various software (spyware, viruses, other malware) can be installed. There is no patch at this moment, I don’t know of my AV vendors that detect it (f-prot seems to according to their blog posts.) There is a workaround TO PREVENT INFECTION. If the system is already infected, reinstallation may be the only solution.

Here are more details from f-secure…

Disinfecting a PC… part 6

BHOdemon bhotb-all.html not found, no web connection downloading on other machine.

Disinfecting a PC… part 1
This is the first in a several part series documenting the cleaning of an infected PC. The only real noteworthy item is that it was a dial-up only connection and was rather infested for that. (On par with some of the broadband connected pc’s I’ve seen. It’s also an interesting counterpoint to the network security series.)
