Hey everybody, so recently something happened to my computer when i shut it down, but it didn't shut down for a few minutes. So i pressed restart button and after that windows started some disk error checking and fixing. It went through it like in two minutes. When it finished it, the computer booted normally, bit just a bit slow. First thing i saw was my antivirus shortcut appeared out of nowhere.( I deleted the antivirus, because it started doing some shady s*** in the background)(Avast). After that the computer ran a bit better, the startups were more quicker, etc... Getting to the point. After that disk repair or what, idk... I needed to relogin almost to every program. Skype, steam, google etc. Idk why exactly. Also my game settings were set to default (checked only cs:go). So because there were no AV, i turned on Windows Defender, but it didn't do real-time checking (i think that is how it's called) maybe because i didn't uninstall avast properly. So I installed Malwarebytes, but it didn't do any scanning. It just checked for updates and stopped. Can someone explain why my computer did that? And why Malwarebytes doesn't scan?
Thanks from the start.
