I ran a Targeted Scan and found:
An external USB Drive of mine has 189 iterations of this whatever.
How can I know the Targeted Scan Removed or Disabled them?
Does it indicate the specific files associated with that “WIN32:Crypt-SWW[inf]” alert?
I am guessing it is not a malware alert (I could be wrong, others may better advise), but an indication of files that are encrypted and cannot or fail to be scanned by Avast. If so they will not be moved.
I would suggest getting a second opinion, by scanning that drive with Malwarebytes.
