Just got hit with a nasty encryption virus (crypto or some variant) which has encrypted all my Office files, photos, etc. I had McAfee LiveSafe and Zemana Antimalware. Opened an attachment which I thought was safe. An alarm went off on Zemana and a scan started and something was found and deleted. Later I conducted a full scan with McAfee. Nothing. So are there any av's out there that guard against this bit of nastiness? Instructions are included to go to the dark web and pay ransom with Bitcoins to get your files back. Really bad stuff here.
