Brief:
* Using new Acer desktop with Windows Vista
* I just bought a new computer, it had 2 months free McAfee with the option to extend to a 1 yr. contract at a reduced price.
* Before paying for and downloading the extended software from McAfee's website the 2 month trial version worked seamlessly with Windows Defender.
* Now that the download is complete for the Security Center Windows Defender has corrupted, will not open through any method, and displays the issues 0x800106ba and ANIWZCS2 on start up. Th error message recommends restarting the computer but that does not work. The error message also recommends opening the program manually (using Windows Defender of course) which can't be done because the "program" is Windows Defender in the first place. I also can't remove Windows Defender from automatically loading when Windows starts because you evidently have to use Windows Defender to do that too.
Please advise on how to get the two programs to either work together or stop Windows Defender from automatically loading at start-up.
