Runtime Error message at start-up

[Quimbly]

I recently installed some crappy software that I suspect
was somewhat malicious. Now, whenever I boot my system, I
get a run-time error '13' popup window. The title of the
window is "CPP Change" -- real helpful.

I'm trying to figure out how to remove it from my system,
permanently.

I have run a full system virus scan to no avail. The popup
window is tracked to a svchost process (I believe -- going
on memory here). There's no reference to anything out of
the ordinary in the XP Startup folder. I also scoured the
registry for anything to do with "cpp change", finding nothing.

I'm at a loss about what to do next. Any have any ideas?
