This link is for the Spybot support forum for this same problem and will probably answer your question.
I have and run Spybot and I want to like it but due to the following I'm having second thoughts. Each time I run a scan, it stops and reports; Z-Demon (Ungultiger Daten typ Fur). Locks up machine and then I get "The parameter is incorrect". I have read to just ignore this but I want to get rid of this what ever it is! Can anybody help me with this problem. Thanks in advance, Dave
