Please answer each of the following [admittedly tedious] diagnostic questions in a correspondingly-numbered list in your very next reply, preferablywithout quoting this post:
1a. When (approx. date) did you purchase the Win7 (64-bit?) computer?
1b. When (exact date, preferably) did you upgrade to Win8)?
1c. Was Win8 Release Preview (beta) ever installed?
2. What version of Norton Internet Security (NIS) is installed and when (exact date, preferably) does your current subscription expire?
3. Was NIS installed when you were running Win7?
4a. Has any other Norton application or a McAfee application EVER been installed on
the computer since you bought it?
4b. Did a Norton free-trial or a McAfee free-trial [PICK ONE] come preinstalled on the
Win7 computer when you bought it? (Doesn't matter if you never used or Activated it.)
5. Are KB2809289, KB2807986; KB2781197, KB2797052, KB2778344, KB2799494, KB2790655, KB2789650, KB2789649 & KB2824670 all listed in
Installed Updates (not Update History)? [1]
6. Is Firefox, Chrome or any other alternate browser installed and if so, was it already installed when you were still running Win7?
7. Are you in the habit of using "Registry cleaners" (e.g., Registry Mechanic; System Mechanic; RegCure; RegClean Pro; Advanced SystemCare; Registry Booster; McAfee QuickClean; AVG PC TuneUp;
Norton Registry Cleaner or Norton PC TuneUp; PCTools Optimiser; SpeedUpMyPC; PC Doctor; TuneUp Utilities; WinMaximizer; WinSweeper; Comodo System Cleaner; Advanced System Optimizer; CCleaner
