My moms computer is very slow at anything you try and do. Just opening anything can take several minutes. If we try to scan with Avast it takes hours and never used too. Scanning with Malwarebytes took hours and stopped. Web pages take a long time to load, and if you try to open settings and do something it takes a long time for it to recognize you clicked on anything. Everything on it is now very slow!
What could be the problem? I have tried to scan for virus but it never will complete. the disk is not fragmented.
