Well, just a short while ago my laptop randomly shut itself off, and shortly before the screen went black there was a quick blue screen. No text on it, but got a blue screen then it shut itself off. After that, it wouldn't turn back on for a good 15 minutes. When it finally did start back up, it took another 5 minutes just to turn on.
After turning back on, I went straight to windows firewall and defender. I know they're not the best and all, but yeah. Anyway, upon trying to get into them or change the settings for them, I get errors.
For windows firewall, I get an error that says "Due to an unidentified problem, Windows cannot display Windows Firewall settings."
For windows defender, I get an error that says "Application failed to initialize: 0x80070006. The handle is invalid."
I also get another error when trying to turn on the security center which says "The Security Center service can't be started."
I'm guessing this is a virus of some sort, but up until this problem I've had absolutely no problems with my laptop, so it's worrying.
