I know how I got infected and won't be doing those particular things again.
PC in question: Windows XP Pro SP3, Norton Anti-V Corporate, System and apps installed on separate partitions, Boot from D:\. Please ask about anything I have forgotten to include.
My desktop PC started to get wacky, with this Protection System fake virus/spyware/fake software taking over. It has the system tray item and many random pop-ups. Google search results were mis-directing. Desktop shortcuts to porn and Protection system being generated on startup. General mayhem. In the process of trying to fix things I disabled a process called "##Id_String1.6844F930_1628_4223_B5CC_5BB94B879762##" and most of this behavior stopped.
Some other things make me think there's something else going on. I can't run/install Malwarebytes, rootrepeal, combofix, and some others. Combofix Blue-screened the few times I tried to run it. Renaming things made no difference. Malwarebytes just plain fails to run after an incredibly long install time, but it shows up in Process Explorer.
No volumes show up in Disk Manager.
At this point, I'm considering re-installing Windows, but I'm worried I'll have to format both my drives and start really clean, which I'd rather have the machine running well enough to archive my stuff with my burner instead of moving things around on a thumb drive or something equally painful.
For the most part, I'll use my laptop to d/l apps I need and move them with a thumb drive. If I need to put the PC online, I will, but I'd prefer to not expose it to the internet any more until it's clean.
Any help would be greatly appreciated.
**edit** I will try to respond as quickly as possible, but I'm on-call this week and may be tied up.
