A number people have been picking up a very tricky and hard to isolate Spyware viruses from X-tube.   Yes, I’m certain it was from X-tube as it was traced back there via the “Jasmine” pop up site.   I had to re-start in Safe Mode with Networking and have a IT friend go through and delete them.   I also ran MalwareBytes (free edition) which also seemed to help.  I wish I had the particular name of the viruses but apparently I had quite a few.
