"XP Antivirus 2008"

Hi:
Pentium 4 XP sp2.
Having much trouble.
My "All Programs" disappeared and I don't even see "Run", either. No visible access to "Doc's & Settings" but "XP Antivirus 2008" keeps taking over the screen, posing as Windows Security Centre.
New user. I ran HiJackThis, but it is zipped and I don't know how to send it to you.
Please help me get through this?
Can I do something in Safe Mode to bypass all my missing "Information" and run a virus check without all the pop-ups?
Many thanks.
Nate G.

 

Thank you Laura:

I am unable to uninstall HiJackThis because I have no 'Run" option, when I click my 'Start" to access the Registry.
I tried to uninstall it from Add/Remove, but it said it's running and wouldn't let me uninstall. I thought I could unclick it, in the Start-Up option in Registry.
That's the main thing - I can't access "Run" at all, in order to type "msconfig" and follow further instructions.
I'm sorry to have to ask this before I can get started with the instructions re Malware removal, but I don't know how else to Delete HiJackThis, or how to find, "Run", since it's not in Start.
Thanks!
Nate
