Fortunately, it was easier then I thought it would be. I got him to boot into safe mode & did a system restore 2 points back. He says it runs like it did before. Whatever it was, it wasn't that bad.
Thank heavens. we're talking about a guy in his 80's that just got the PC a year ago & knows nothing about computers. I had him d/l Malwarebytes & run it. All clear. I had him put MSE on the system too.
(When he booted into safe mode, he was totally amazed by the fact I knew/there was a "Hidden thing". I also had to explain that software is just that, doesn't matter if it's from Canada)
Yes Solarstarshines, I asked him if he ever entered the "Canadian Lottery" & he couldn't recall. He thought that maybe since he was online, he "automatically got entered". I warned him about scams like that.
Unfortunately, there are a lot of instances like that. In the past I've seen messages like that saying my ticket in some foreign country had won & they needed info to send me the cash. And, unfortunately, it's usually the older people that fall victim to those scams.
