John,
Before you surrender, I suggest a visit to the Safer Networking site. These are the guys that
make Spybot, and they walked me through a process last fall that completely fixed a hideous
infection called Virtumonde. They have half a dozen tools that they use to look over your system
and fix it. It's a detailed process, and your communications may take place over a couple of days,
but it gets fixed. Here is a link to my episode, where they started me out with their Hijack This
utility:

They saved my computer, and I was so impressed I donated $50 to Safer Networking.
Also, the Spybot program is one you should have installed and running regularly, it has a
resident program called Teatimer that intercepts attempts to alter your registry, which
saves you in most cases. Safer Networking points out that several of the more
virulent trojans are exploiting some special Microsoft IE "object" to propagate
themselves, and helps you deal with that.
Safer Networking also links to Malwarebytes, and has suggestions for using it.
I've had very good fortune avoiding problems on my current computer after the
Virtumonde incident. I have installed and use the following security programs:
Norton 360
Safer Networking's Spybot with Teatimer
Malwarebytes
At least as important is your internet browser's security add on
programs. I run Firefox, and have the following add ons protecting
it:
NoScript
Adblock Plus
IE Tab (opens an Internet Explorer compatible tab)
I also cleaned out all non-essential cookies, and set the security to allow
cookies, but discard them on exit. Similar deal with cookies on IE setup.
It's a slight inconvenience to allow new cookies, but well worth it. Also,
disable redirection from any selected site until it is known trustworthy.
It takes awhile, but eventually you're allowing the safe sites you can
trust, and avoiding masses of troubles.
Keep your antivirus program, plus Spybot and Malwarebytes all up to date and
run them regularly (I run them daily at 3 AM), you won't regret it.
Safer Networking has three free utilities that I downloaded and found
useful: RegAlyzer, FileAlyzer, and RunAlyzer for looking at registry, files
and run configurations. FileAlyzer is great for examining virtually any file
and getting a hex/ascii dump.
This is the very best advice I can give you. Good luck!

Edit: forgot to mention I'm running Windows XP Pro. All bets are off for Vista
or Windows 7, I simply have no experience with these operating systems..
