Alright. . . here's what you need to do.
First, reboot the computer
. This ought to resolve the error message that keeps you from doing anything.
Second, since ComboFix did run, and it found and removed files, the best thing to do is get the situation checked out by a member of our malware removal team.
Please follow the instructions in This Guide
starting at Step 6
Once the proper logs are created, then make a NEW TOPIC
and post it HERE
Please include a description of your computer issues and what you have done to try to resolve them.
If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.
Additionally, please post your ComboFix log in your new topic, and provide a link to this
topic. I'm going to remove your log attachment from this topic because ComboFix logs are handled only by our malware removal team in their specialized forum.
