I've just done an update of the latest detection rules from Spybot S&D and was somewhat disconcerted to find that the process took much longer than usual - and initially failed! I got an error message saying that the 'checksum' did not match. So I had to try again. Eventually it all came good and when I did a scan, to my surprise, I had no DSO Exploit FP! Strange to fix this bug after so long - and I'm still using Version 1.3!
