Hi Rob,

In my UNeducated opinon you have been badly infected.
I am NOT a security cleaning expert.
For a more expert analysis and clean up would you mind opening a thread at BleepingComputers,
Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help - Virus, Trojan, Spyware, and Malware Removal Logs
They are very good but overworked.

XREF this thread as well, the more info the better.

Thanks for your feedback Roy. This is one really sophisticated virus, because even virus scans don't find it. Here's some of the things I tried, since my last post, and resulting error codes.
I tried deleting all the contents of C:Windows/SoftwareDistribution folder, as per MS's site. Those deleted once. Then I ran the Windows Update. Didn't work. Now I can't even delete those contents anymore.

Then I tried running SP1 update from a DVD I burnt of the ISO from Microsoft's website. "A system error prevented the service pack from installing. Please download and run the"Check for System Update Readiness Tool." Here's the error code.
Of course I downloaded that Service Pack and tried to install it, but that failed too.
This is the error code for the failed (KB947821) Code 80073712
Man, this is driving me insane.........and you want to open up another ticket at BleepingComputers??
I guess I'm this far down the rabbit hole now,......I might as well continue.
Thanks for your help!

I fixed this by inserting my Win 7 CD and choosing Upgrade. It repaired all my Windows files while keeping my Programs in place. (I didn't know you could do bad) Anyways, all the corrupt files are fixed, I'm now able to update Windows in the normal fashion, and I have SP1 installed.
Thanks to all of you who offered assistance. Sorry to have wasted your time on something I could have fixed on my own, had I known the solution was there. Now I know!!!
For any who are curious, it wasn't a virus it was corrupted files from installing faulty RAM. Thanks God, I back-up everything in Triplicate.
Anyways, safe journeys............and I'll see you guys next time catastrophe strikes!!

Well done Rob it doesn't surprise me you have got it fixed that way because stranger things happen at sea. For example my main Ivy Bridge desktop dropped all the USB ports a while ago and the culprit - the Samsung Magician software uninstalled it and back came the ports after a coupe of months trying everything - and more recently solved a heap of slowness and annoying bugs by just replacing the CMOS BIOS battery - again something that doesn't come straight to mind

At least you have been backing up and yes I use this for doing my backups because you can set it to do it at regular times ie weekly so am always up to date Imaging with free Macrium

You might be interested in this too it will speed up and make the machine more efficient if you don't mind losing some of the "bling" like transparency (you don'y have to lose that necessarily) I use it on all my machines
