I am bad at this kind of stuff, so apologies if I am missing something obvious.
Today in a scan a "tracing key" is detected after a scan with adwcleaner, deleted it and right after restart I scanned again. Same key was detected again. Malwarebytes scan didn't detect anything. After 2 more deletions with adwcleaner I thought I would ask here for help since it still keeps popping up in adwcleaner. Here is the last log file:
