@TwoShoes,
I'm sorry if I misinterpreted your previous posts. I had no bad intention. When I read the topic, including Pondus insistence on reading again the instructions, I was under the (now I know to be wrong) impression that you were not only not reading the full instructions carefully enough, but also running tools or changing settings when was not specifically requested (for example, (re)running some tools when not requested to, may have bad consequences in some situations).
As I said, this was my impression, and from you last post I understand I was wrong about it. In any case, the fact remains: essexboy usually "cleans up" his work and tools after the main issue is solved. If for whichever reason Combofix (or any other tool) is not needed anymore, essexboy will tell you when and exactly how to "clean up".
About the "PEV" issue, I also read that other topic, but as of right now I have not seen a concrete response. I don't know if this is a FP, or that some other setting should be used (as I said, sometimes some tools are supposed to be ran with avast shields paused, as an example).
I would suggest waiting for essexboy so to follow his next instructions.
