Hello, I am posting as it seems that my PC is severely infected and I am unsure how to proceed. I first noticed when Windows Powershell opened by itself every time that I started my PC, and that it would randomly restart itself. I downloaded Malwarebytes and ran a full scan which came up with over 13,000 threats, which I quarantined (the attached scan file states that I took no action, however Malwarebytes shows that they were all quarantined). The Powershell issue has not returned since then. I attempted to delete all of the quarantined files, however nothing happens when I select the delete option. I am hoping that someone can point me in the right direction on how to ensure that my PC is safe. Thank you in advance!
