2 nights ago our laptop was left on all night, when I woke up the computer was not running properly at all. Extremely sluggish and barely opens any programs. I had a hard time getting it into safe mode to be able to write this out. I tried running malwarebytes a few times with varied results. First few times it just wouldn't open and the computer would freeze shortly after. I ran rkill before malwayrebytes and one time it scanned about 400k files, found 3 threats in 30 minutes and then got stuck on heuristic analysis for over 4 hours before I canceled. The last time I ran it was scanning extremely slow and had only scanned 3.2k files after over an hour.
In safe mode the computer it runs fine with no issues. It seems when I start in normal mode it runs smooth for about a minute then everything locks up. Nothing responds and eventually I have to turn the computer off by the power button. The night before the computer was running with no issues at all.
If anyone can give many any ideas or advice it would be greatly appreciated. I'm willing to try whatever it takes at this point. Thanks.
