"We can't sign into your account" post-removal process

[alyssa2017]

I'm not a huge computer wiz so please let me know if there is any addtl. info. I should provide.

I have a windows 10/microsoft surface pro 4 with i5. 

So I had some virus on my computer which installed literally tons of random crap lol. Malaware and adware and I don't even know. Anyways, windows defender clearly wasn't working so I eventually got Malwarebytes. I ran a scan and it then prompted me to restart my computer so I did. Now I get this error message when I try to sign in. Previously, it signed me into a temporary account with the error message. Then I restarted with safe mode and now I just get the black screen with the error message. I can't access any of my files and I don't know what to do because I have two exams to study for and need my computer and am low key freaking out haha. Please help!!! Thanks so much in advanced.

UPDATE: Still not working, but I was able to login to an administrator account in safe mode. I also changed my microsoft password (but the password that got me in was actually my old one lol). Now I'm running another scan with Malwarebytes through this admin safe mode account. No clue what I should do next, though, since I still can't access any of my files.

You should be able to go into the Control Panel, Manage User Accounts and change the password for your account. Then you should be able to login to that account. Please give that a try and let me know.
