Same thing here...
Yes, I also got the same error trying to install V2.9.6.0 of DVDFAB Platinum.
To test this, I completely uninstalled both programs, DVDFAB and spybot reinstalled spybot without the latest update and re-ran the installation.
Resut= No problems.
Uninstalled DVDfab
Updated spybot to the latest definitions and re-installed DVDFab.
I also tested this by trying to install an earlier V2.9.5.9 of DVDfab and got the
same errors using the 18-NOV-05 updated definitions.
Result= Failed install with "winfixer2005" error.
I then installed the program telling Teatimer to allow it to run anyways. I then did a search for uninstalling 'winfixer2005' to find out where it puts it's files, registry entries, etc, etc and searched for them on my test system.
There were no instances of 'winfixer2005' on the system.
This looks like some kind of 'false positive' error by Spybot Search & Destroy.
