When I run Spybot - Search & Destroy version: 1.6.2 (build: 20090126) (Win 98SE) with the latest definitions I receive the following error:

--- Search result list ---
Error during check!: Win32.Autorun.cfto [1 - $759C99D9] (TRegExpr(comp): *+ Operand Could Be Empty (pos 1)) (Status)

Am I infected with this malware? How should I proceed?
