Hello. I have relied on bleepingcomputer.com to help me through numerous little problems over the years, but I never became so infected that I needed to post. This past week, after foolishly downloading a free music file, my PC developed a ransom infection: Antisyware Doctor. My PC was so mucked up that I couldn't do anything to help it, even using a second computer and following the instructions on bleepingcomputer.com. I had to give up and take it to a "professional" for help.
Well, the guy did a pretty good job -I thought-- until I brought it back home and ran a Malwarebytes scan just to be sure. Malwarebytes picked up 13 infections! While it was running, my Trend PC-cillin popped up and notified me of another half dozen infections, with some being ".dll" files. Despite my better judgment, I deleted all the ".dll" files that were picked up by PC-cillin and Malwarebytes took care of the rest. I've run multiple malwarebytes scans since then and nothing is getting picked up.
However, I am still having a BIG problem: Internet Explorer will not run. I have tried downloading version 8 again, but it doesn't fix the problem. Each time I try to reinstall IE, the re-installation process will continue to the end and then two pop-ups will appear that tell me certain ".dll" files are missing. Other than this (which is quite alarming) everything else seems to be back to normal. What do I do now and how do I make certain that I am 100% free of infection?
Here's the Mallwarebytes scan after I brought my computer home from the "pro":
