When (approx. date) did you install Microsoft Security Essentials (MSE)
and was the computer fully-patched at Windows Update at the time?
I installed it about 6 months ago and the computer was fully-patched at the
time
What anti-virus application was installed before you installed MSE, was
your subscription still current, and did you uninstall it before you
installed
I was using McAfee downloaded from Comcast before I installed MSE. The
subscription was current and I used the complete uninstall instructions and
tool supplied by McAfee via Comcast before installing MSE.
Has a(nother) Norton or McAfee application ever been installed on the
computer?
Norton was installed, but I used the uninstall instructions and tool from
Norton via Comcast before installing McAfee. See above regarding the McAfee
uninstall before moving to MSE.
Did a Norton or McAfee free-trial come preinstalled on the computer when
you bought it? (Doesn't matter if you never used or Activated it.)
Norton was installed and I later upgraded it to the full version. Norton
then ran on the computer for several years before installing McAfee.
Thanks for your help
