SpyHunter 4

A virus got onto my desktop.  It started putting a bunch of files with the extension .osiris on the harddrive.  Googling on osiris  informed me that Malwarebytes (which I have and use and trust) and something called Spyhunter (which I had never heard of before) would settle osiris's hash.  So, I gave malwarebytes a run, and sure enough, it reported some viruses, and zapped them.  So just to make sure, and to see what would happen, I ran Spyhunter.  Not so good.  It crashed once.  Then it ran and found a list of stuff it didn't like.  So when Spyhunter finished scanning, I clicked to make it zap the stuff it found.  Instead of doing what it was told, Spyhunter demanded I pay $40 for the fancier version of the program.
   No way would I do that.  I  used Windows Explorer and Regedit to search for the objects Spyhunter was objecting to.  No soap,  I could find neither disk files nor registry keys to match anything Spyhunter reported.  So, I uninstalled Spyhunter.  I cannot recommend that program to anyone.
   I still have a bunch of .osiris files on disk.  And a file demanding ransom to decrypt them.  I'll do some more research tomorrow.
