Today on my windows 10 computer was a message that I had a Trojan. Long message with an 855 number to call. when I clicked the X the page disappeared then the cursor arrow was moving all over on its own. I have been running MBAM for nearly two years. When I went to check on it, it said it needed an update which I licked on. Then it disappeared. When I went to the apps list and opened the MBAM folder there were only three shortcuts shown, but no program. Any thoughts?
