suspicious Windows.old file
I have a custom built computer that has only had W10 on it. 2 weeks ago I couldn't get on the Internet and it took several techs to figure out why - it was some kind of malware that didn't show up in any scans, put "Killer" in the systray and popped up a screen showing SoundBlaster. The tech didn't think either one was legitimate. Both were installed the day the computer went down and when they were removed, things seemed fine. I have had 2 BSODs since that said "Bad Pool Leader" and today I noticed I have a huge file in my C drive, "Windows.old", which was created that same day. Since I have never had an upgrade, I know this isn't a normal Windows file. Can I delete it without a problem?
Thanks for any suggestions.
