I get a pop-up from Mcafee that says my computer is at risk. When I open Mcafee, it says the real time scanning is turned off. When I turn the real time scanning on and try to perform a scan, I get another pop-up window that says an unexpected error has ocurred and to click the OK button to go back to the home page. When I go back to the home page, the real time scanning is turned off. I have a licensed version of Mcafee Security Center, Virus Scan, Personal Firewall, Site Advisor, Anti-Spam, and Parental Controls that expire in March, 2011.
