2017-06-06 You will see a couple random folders created on C: If you delete the folders they will be recreated with different random names shortly after. I thought I had a virus at first and it took awhile to figure out what was creating the folders.
If you are looking for free "ransomware" protection . . .
Who knows if it works but it is an active little bugger. At times it takes numerous resources but not constantly. It is not intrusive. I've used it for about a year. I've read how it works and it seems a reasonable approach. It creates a little ransomware honey pot, some files in a place ransomware loves to attack, and it monitors those files. If something tries to change those files it shuts that process down. Nothing will be 100% effective. I imagine you could lose some files unless the ransomware hit the "honey pot" first.
