I have SpyBot Search and Destroy - new, I just downloaded it last week (after uninstalling the version I had before, in case the problem was in that version.) It shows that it has 21,097 spyware signatures, and shows its progress going through them. I get to about 6200 and it suddenly stops - showing "all clear" for the part it searched, but with this message too:
"Error during Check! 2020 Search (ungultig Datentyp fur ")
The German means invalid data type for "
So something is blocking about two/thirds of the search for spyware. The Help function in SpyBot has not been useful.
