[Closed] Problems with drwtsn, dwwin & imapi

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!

Please do the following:

Please download DDS from either of these links

Thank you so much for your quick response!! After reading the following, please let me know if I should still do the scan that you suggested in your reply.

After trying a System Restore three times since Wednesday (they wouldn't work), I tried one more time last night and set the System Restore to Tuesday (the day before I downloaded the Photoshop Brushes) and it finally worked.

The System Restore seems to have fixed the problem I was having, as now I can right-click, move pictures, move items on my desktop and haven't had any issues from drwtsn/dwwin/imapi showing up.

It did, however, delete at the very least, half of the Photoshop Brushes I downloaded on Wednesday. I don't understand why it only got rid of about half of them and not all or none of them. That's not a big problem though, I will just go through and see which ones I'm missing & re-download them - but scan them with McAfee before I unzip them to make sure they are okay. Does it sound like it may have been one of the brushes I downloaded??

So, as I said, it seems like everything is back to normal now, but please let me know if I should still run the scan you suggested.

Thank you SO much for your time!!

It it hard to say what may have infected you. Lets run the scans just to make certain there are no infections remaining.
