So, a couple of days ago I was happily playing some video games on my Windows 10 laptop. Then I though "Better check my computer for any viruses"; after scanning I found 8000+ viruses (most were just duplications of the same malware). After waiting an hour or two for these all to quarantine (thank Malwarebytes for being slow), I then used AdwCleaner to check for any adware. I then proceeded to restart after everything was completed. After restarting I was unable to get into Windows, I had been locked out. It would either keep me in a "Welcome" loop or would just not allow me to in put my password. I can boot in safe mode however I cannot access File Explorer it just says "This app can't open" and then "Tips can't be opened using the Built-in Administrator account. Sign in with a different account and try again". However on the desktop and in the start menu I can open File Explorer just fine, it is only when I pin it on my task bar and then click it; it does this strange 'refresh' thing and then states the error I just mentioned. I have already tried everything, from attempting to reset, startup repair, etc. Nothing seems to work and I am starting to think I will need to buy a Windows 10 disk (because my computer did not come with a disk) and somehow wipe my SSD which contains the install of Windows 10. However if anyone has an idea I would be glad to try it.
