Hi all..

Suddenly getting Windows Security detecting 'Behavior:Win32/Powessere.SA' and safely removing it since mid-saturday. There doesn;t seem to be any file location etc reported, and I don;t see any files or emails being downloaded at the time it started.

It's happened 4 times so far. Any ideas?

Thanks

Microsoft has a very vague description

This generic detection for suspicious behaviors is designed to catch potentially malicious files. If you downloaded a file or received it through email, ensure that it is from a reliable source before opening it.


Defender should take care of it, but if it keeps showing, it's possible it's a false positive. Hopefully someone with more security experience will be able to get deeper
