Victory

Waged a battle over the past several days against some spyware progs my laptop picked up while surfing for keys. Came to a head last night and finally, at long last, the dreaded dll's fingers on the ledge finally let go, and they were wiped off the edge into oblivion.

Ran at least five different anti-malware utilities, including ewido, Microsoft AntiSpyware, CCleaner, Ad-Aware, Spy-Bot, and XoftSpy. Finally stumbled upon the win32delfkil package, which, when combined with ProcessExplorer for killing the winlogon.exe process (the Beyond Logic utility entered an infinite loop while trying to kill it), did the trick in isolating the rogue dll's (adsldpbf.dll, browsela.dll) and ending their miserable existence. Thank God for forums.

Gonna have to take much greater care next time I need to find a key.
