If this will help, someone who I thought was a friend was caught stealing from me. He was trying to set up my computer for remote access (failed) when I threw him out. I immediately changed all passcodes, just in case. My McAfee service is showing me that he is still trying to access my computer from the outside, but can't get in. So I suspect he did something prevent me from searching my C: drive and find any files he put on there. I haven't found any new programs and I have my setting so hidden files are displayed.
Is there a way to restore my SEARCH function?
Thx.
