To all users of SpywareBlaster and Spybot S&D,
There is a thread going on at Spybot S&D Forum and Wilders Security regarding access violation in SpywareBlaster after installing the latest update by Spybot S&D.
If you are affected, the work-around is to temporarily disable Firefox Immunization by Spybot S&D
See the discussion at http://forums.spybot.info/showthread.php?t=26890 and http://www.wilderssecurity.com/showthread.php?t=206415
I've tracked down the cause of this error.
This problem is being caused by Spybot S & D writing invalid entries to the Firefox hostperm.1 file.
Specifically, Spybot is writing entries using unicode characters, such as:
This is invalid. According to the specification, these International Domain Names should be properly encoded as punycode before being written to the file. In the case of the domain listed above, it should be written to the file as:
(More information on punycode, for anyone who's curious: http://en.wikipedia.org/wiki/Punycode)
For the time being, I would recommend undoing/disabling immunization for Firefox in Spybot S & D - to prevent Spybot from writing these invalid entries to the file.
This should allow you to fully enable protection in SpywareBlaster.
Other Notes (for PepiMK):
A quick fix on Spybot S & D's end would be to simply remove those sites from the database, until the Spybot program itself is fixed to write the properly encoded entries to the file.
