Looks like bitdefender is blocking winbox from RouterOS 6.0 thinking it’s a virus.
Useless piece of junk didn’t even restore the file when it was told to and was blocking subsequent re downloads of winbox, Since it seems impossible to tell this AV software who’s in charge it’s now uninstalled.
Winbox.exe uses a packing mechanism that some antivirus tools don’t like. It doesn’t have any virus.
I’m guessing it was a duff definitions update as it used to be fine with it
Anyway seeing as apparently Bitdefender isn’t capable of the simple task of restoring a file from quarantine when told to it’s gone from my system.
Also just noticed my typo in the topic title
