One point to note that may have something to do with it?
After receiving my Mac back last week from Apple where they determined that there was a hardware problem & replaced the wifi card (or something like that), I had to do a complete restore from my Seagate external back up drive. When I plugged it in to do scan once the contents was transferred (took a few hours), the scan detected a virus but where? I followed the instructions & removed any DVD, CD, external drive then ran the scan again. No threats were detected. good. But now despite not reconnecting the backup drive for several days, I am getting the alert message mentioned above.
It would seem that the virus/bad files are in the backup drive (new since maybe February & contains the contents of the former backup drive that failed). But if this is the case (1) why would I keep getting the warning message when the backup drive is not connected? (2) should I reconnect the backup drive & see what happens? I DO need to back up soon!
Thank you for your input.
