This is a bit confusing, in other posts by Avast, this is considered a false positive.
My macbook shows 6 infections (including 2 timemachine copies) and has been scanning now for 25 hours and has been on 99% for the last 18 hours, still actively scanning. I run a fresh version of Avast, only bought it 2 days ago.
If its a FP, I would appreciate a heads-up and continue with normal life on this machine....
Thanks for any support.
BTW, the captcha is at times indeed above challenging
