When I run the anti-virus program on my 1-year old computer using Windows 10 Avast it freezes at 41% complete. I also had a popup today indicating my computer may be infected and to call microsoft. It was all in read and I am guessing that was fake. In looking at the history in Chrome, the popup came from mainrdrct.global.ssl.fastly.net and adverrd.global.ssl.fastly.net
I believe Malware bytes found the trojan Kovter last month but the program updated last week and I can't find that log. A new scan by Malwarebytes did not find anything.
