My problem ended up being some malware my son let in and he overrode McAfee. I went to Ask.com and entered something like "mcafee was turned off and 'my security shield' turned on". The search turned up some step by step instructions to walk me through getting rid of the problem. Seems like a lot of people have had this problem since 8/19. Ironically, the site I ended up using was a community from McAfee - pointed me to the following http://www.bleepingcomputer.com/virus-removal/remove-my-security-shield.
I am experiencing similar problems to Airtuna08. It started about 3 weeks ago and it appeared that everytime I restarted my computer to install McAfee updates I got the Blue Screen of Death. Now it appears to be tied in with "Security updates for Windows 7 for x64 based system" and "Updates for Internet Explorer 8 for Windows 7 for x64 based system". - I cannot install these updates. Now everytime I restart my computer I get the BSOD and have to restart in Safe Mode and restore the computer to the previous day. As an aside my McAfee program appears to have disappeared. I tried to reinstall it but when I restarted my computer to finish the installation I of course got the BSOD and had to restore it to the previous day and therefore lost the download. My BCP codes are the same as Airtuna08 except that BCP4 is FFFFF880014F75D6. Any suggestions?
