My McAfee just gave me this message "The On-Demand Scan found alterations to code or data which may indicate that a rootkit is attempting to hide files, registry keys, processes or other items. If this scan fails to find anything then the computer should be scanned with McAfee PreScan or booted into Safe Mode and this scan run again"
What should i do?
I don't know if i have McAfee PreScan and i don't know what safe mode is.
Any advice would be GLADLY recieved.
