Hello, I have a Dell Inspiron Laptop running the following: Vista Home Basic 32-bit OS Service Pack 2 Beginning this afternoon, my PC suddenly began slowing down to the point that every program would either not respond or not open. Startup takes a long time to load and never finishes. I'm unable to shut down the PC through the OS; a forced shutdown is required. I don't know if it's a virus, malware, or something else. I tried to begin with the TechSpot malware removal process, but I can't run my antivirus (McAfee) or Malwarebytes in either normal mode or Safe Mode. Please let me know if you can assist. Thank you.
