About a week ago I noticed my computer acting funny after an automatic update had been done. Then it started becoming worse and more obvious so I did a few scans with Malwarbytes (quick and full) and it showed 3 infections but were quarantined. Computer seemed fine, but then later started acting weird again. Ran the scan again, showed nothing. But my computer was acting weird whenever I tried to go online. Did a system restore, seemed to fix the problem.
Except that each morning whenever I get back on my computer, I see that it's been shut down and restarted (like it does whenever it's had an update). And the same weird problems getting online happen again. Each time I do a system restore it fixes it.
But now I cannot log into the company database. I am able to connect to the VPN, but can't access the database.
Do I have a virus? What can I do to fix my computer?
