Which my brother has had access to.
Unsurprisingly, it's completely loaded with virii, spyware, and other assort malware and garbage.
Two different virus scanners, and two different spyware scanners came up with a total of 11 virii, 144 different pieces of spyware or adware, and 2557 infected files, cookies, and registry entries.
Normally I prefer to wipe and reinstall a system that is so infected; but I think I've got all of it; and locked it down enough. Now I'm going to let it run for a few days and see if theres anything lying dormant waiting to reinfect the machine.
More detail to follow.
