Thank you very much to work on my Problem. Im not a native English speaker so exause me for some grammatical mistakes etc…

To the first part: Done

To the second part:
FRST and Fixlist.txt was on the same Location.
I selected “Run as Administrator” und pressed the “Fix” button.
After a while Avast Blocked FRST. The location was as far I noticed the location of the tool, the Infektion was “FRST.exe”.
I didnt find the Fixlog on my Desktop so I thought I give it another try but it seems like the FRST.exe is deletet or something. Well I guess Avast did smt to that. However I found a Fixlog.txt in my music folder. I dont knowe if its fully complete but I think you will find out ;).
