How do I reformat my C Drive?
So I had a nasty virus, removed it from the control panel, but now my antivirus' and malwarebytes won't work..even in safe mode! It says I do not have permisson. My computer runs slow as anything! Should I reformat or is there something else I can do? System restore did not work either :( Should I buy an antivirus (disk form from Best Buy NOT off interent) and try that? HELP!
