i just spent 7 hours over the course of two days locked in a gritty battle with this son of a bitch. it is self-replicating, and spawns an ad client named Aurora as well as a few other shady background-type processes with suspicious names like dfjkal.exe or rruqfh.exe... nasty nasty stuff.
had to use a powerful cocktail consisting of spybot, ewido, adaware, MS antispyware, norton windoctor, and hijack this, as well as a custom-made .bat script-- in safe mode, no less-- before i could finally claim my victory
worst part is i didn't even get it from a porn site, i got it from a guitar tab site
