Hi, @Havoc:

Thanks for posting the screen shots.
Even more helpful would be actual scan logs from AdwCleaner or whatever tool has been picking up the detections.

All tools, including AdwCleaner, can have an occasional false-positive.
Likewise, all tools can have false negatives or can miss items that other scanners find.
No two scanners will detect the exact same files/heuristics.

I am not saying that you are necessarily infected with bonafide malware or even with PUPs.
Without scan logs and more data, it's really impossible to say for sure.
We can only speculate.

As none of our resident malware experts has responded here in this thread:

If you are concerned, then I respectfully suggest that you might want to follow my earlier advice HERE to get a bit of free, expert, guided help checking the system.
Trained malware experts will know which tools to run and in which sequence to set your mind at ease.

If, on the other hand, you think that the detections might be false positives by AdwCleaner, then you may wish to report them HERE so that the developer can adjust the database accordingly.

Cheers,
MM
