Hi everyone,

My dad was experiencing some hard drive thrashing on his computer recently, so last night I had him install Malwarebytes' Anti-Malware and SUPERAntiSpyware, and ran a scan of each of the C: drive. SUPERAntiSpyware found no problems, but Malwarebytes' found one. I will paste the log below.

I had not heard of the Trojan.Dropper before, so am just curious -- do any of you recommend that he does more than this? I know that sometimes trojans can be hard to get rid of for good. I can have him install HiJack This and post a log here, if you feel that would be helpful.

Since he ran this scan, he said the hard drive still does some thrashing, but not as much as it was doing before. I don't have much experience with hard drive thrashing, but from the research I've done on the net, it sounds like it could be caused by any number of things, so I'm not really sure what else to do. He's running Windows Vista, so I'm wondering if this has anything to do with it. (I still run XP on my computers.)

As always, any help or suggestions are greatly appreciated.
