I did some Photoshop brush downloads on Wednesday (11/4/09)...I guess this may have started the problems I'm having - maybe one of the files was infected??

Thursday morning I uploaded some pictures from my camera & when I right-clicked in the picture folder to re-name several pictures at once, an error message came up saying that windows had some problem and had to close. I continued trying to re-name the pictures, but everytime I right-clicked or tried to move them to a new folder, the same thing happened & it closed. I have the task manager up a couple times a day just to check on processes running & never noticed drwtsn.exe before. I did some research and know that these programs are critical & so I haven't deleted them, though I see them as the problem. drwtsn.exe pops up first. I end that process tree. Then dwwin.exe pops up and after I end that one, imapi.exe sometimes pops up. Now why imapi.exe pops up since that has to do with CD burning, I don't know.

I have run the Mcafee scan, the CCleaner, the SystemCare scan, the Malware Bytes, the Adaware...I think that's all of them. The only thing they've found are the pretty harmless missing file extensions & cookies, which were then deleted. None have found any virus or trojan or anything. I also ran HijackThis. I didn't do anything with that...I did send it to the main analyzing site though. I've been running these scans for the last two days & still having the drwtsn & right-clicking problems. I am out of ideas. Please help!
