Hello, just recently I became aware of a possible infection on my computer. 2 days ago I restarted my computer back to factory settings but then I realized that instead of Command Prompt, something called Windows Powershell had popped up in it's place. My computer has been acting weirdly ever since this changed happened as well (even now, it freezes for 2 seconds and the command prompt appears then disappears, and has possibly interfered with internet connection) so I have reason to believe that Powershell is the source of the virus. I'm not exactly sure where to start- Windows defender was off for some reason when Powershell appeared, and I never downloaded any other antivirus so that may be how it got into my system.
Thank you!
