I have mcafee for antivirus and I can't really buy any downloads. How do I defrag on windows 7?If you can use system restore to restore to a time before that started happening, then that is your easiest way out of this. Otherwise, start by downloading CCleaner in safe-mode, and running it, followed by Malwarebytes antimalware. Remove any unneeded programs and perform a defrag as well.
What antivirus suite do you use?
