Hi essexboy- He said it was a red Avast! window in the lower right corner… not a very savvy guy, but he followed the onscreen instructions and said it was deleting all sorts of “infected” and “corrupt” files. A lot ended with “adw.” That’s all he can remember. I feel terrible, because I recommended the Avast! free version to him. Apparently, it was scanning for about 15 minutes, then his computer turned off. When he asked me for help, Windows said it couldn’t start up, and said it would attempt repair and restore. But it shut off during that process, and after starting up again, ran for about 30 seconds, then just shut down completely. I’m freaking out, because I feel responsible for suggesting Avast! in the first place. :frowning: Thank you.
