Today, Malwarebytes (v4.1.0) running on Windows 10 Pro (v1909) has flagged Winbox (v3.24) as being malware, and quarantined the winbox64.exe file. I suspect that this is a false positive because I have been using that version of Winbox for a few days but only today has it been flagged.
For information.
Ok “malware” is maybe a bit of an overstatement, but marking as “unusableware” would be appropriate…
Winbox is fine, that was fluke false-positive
Saw that as well this morning having my cup of coffee and I get the pop up on my laptop telling me 3.24 is malware. Never had that with any other version. I suspect the same, just a false positive.
I have reverted to Winbox v3.21 and everything now OK for Malwarebytes. Besides, the interface is more stable (zoom issues on laptop screen) than v3.24 
Thats par for the course with MB. It flagged a bill payment feature on my bank website, after logging in, as malware LOL.
Oh I get it, you are mad that us idiots who cannot manage CLI have a tool that lets us bypass all that silly CLI nonsense 
(well except for a few commands that are quite useful)
No issues here with Malwarebytes v4.1.0 and Winbox64 v3.24
There were infected versions of Winbox, WnRAR, TrueCrypt, IDM getting deployed last year.
