David, OMG! I thought I was the only one. I purchased and downloaded McAfee antivirus. My prior McAfee would have expired in November 2009 but I purchased in October 2009. I've had problems ever since including today. The worse part was that after requesting assistance from McAfee on way too many occasions, I allowed McAfee access to my computer (which I will never do again). After that, I received viruses and trojans. Jee-us!! So, I then was forced to PURCHASE McAfee's virus removal program for $89.00. My program has continued to give me the blues. Today seems like it is about to start all over again. I have left out much because it is too frustrating to repeat. I have Windows XP. Hopefully, we can find help to what appears to be the same problem.
