Serious issue: HELP!

Ok I just experienced a weird crash on my OS. I didn't do a thing, out of nowhere the crash screen appeared, but it wasn't blue it was bright orange. I restarted my computer it continued doing the same thing. I'm running my anti-virus over night hopefully to see if I'm bugged or something. In case things come to worse or anything change your passwords. I've downloaded a database earlier today from Ezud and if something deviant is going on I don't want the site to get fucked up. Has anyone ever seen this or experienced this? My neighbor called me yesterday with a similar problem :/
