My son's been at it again (read exasperated facial expression here). Ran Symantec Endpoint: notification of Trojan.Maljavagen23, some of which could not be deleted. Downloaded Malwarebytes, and am running, but the updating of the virus definitions seemed different than I have experienced before. Did get the updates, and ran scan. Lots of PUP. The reason I started the scans on his notebook was that his screen would show for about a second, then go off. using an external screen works with no problem. Thought maybe the virus might affect the screen?? I was able to run the Malwarebytes and get a log, and gmer with a log, but dss ran for two hours. and froze the computer. I finally just pulled the plug, and rebooted. after the reboot, I again disabled the Symantec Endpoint, and tried to run again. Froze again, it's been another hour. shall I just pull the plug again? the cntrl alt del does not give a dialog. Then (and by the way, once a couple of the virus' were found and deleted by Malwarebytes & gmer, there appeared 31 important updates. (he is using windows VISTA). shall I just post the logs I have?
