Thank you for your time on my behalf.
I backed up my documents, music, photos etc. to DVD.
I also downloaded a copy of my firewall, anti-virus, Iobit 360, and PC Decrapifier (as my PC will return to loaded 2005 programs) to install on my PC before it stats downloading all the necessary windows updates.
I have all my installation CD's and license codes to firewall and anti-virus.
It appears that the downloaded firewall and other programs worked as I was able to open them and install them if necessary.
I also have the latest printout of my system on Belarc Advisor as well as Kaspersky's "Get system info" online program.
Virus scan in safe mode with system restore shows nothing. I don't believe that the PC is infected in any way as I'm extremely careful to keep it locked down through several programs and system settings.
As for CCleaner and other registry cleaners I've used over time, as well as constantly installing and un-installing programs over time. I believe this might be the cause of my present problems.
Rather than attempt to fix the system, I feel a reinstall will be the best and most comprehensive thing under the circumstances.
Once again, thank you for your time on my behalf. I'll let you know how everything turns out.
