Hi, Dialabrain.
Thanks for you quick response and guidance.
Malwarebytes is very user-friendly and I like the easy 'quarantine' function as well. It works perfectly!
Malwarebytes detected the folder 'WFlhS' including the files 'xOetV' & 'qvozP', so I appreciate your tip even more.
I see that
a. different utilities detect different files, although they also overlap. As example:
i. CleanMyMac X did not detect any "malware"; yet
ii. Malwarebytes detected (and quarantined) a substantial list of files (66.3MB for 971 items), neatly grouped with all associated files.
iii. Dr Antivirus confirmed Malwarebytes' warnings of many files, e.g. pennyweight.zx, epioticon, axletree, xcPFinWj, cheechran, ertur, diminutal.sj, rpjxkkztwgyr,
b. Malwarebytes also classified some apps as a threat, yet these are available from the App Store, thus presumably safe to use, e.g. "Open Any File.app" by Rocky Sand Studio.
PS I love your 'name'!
Kind regards
