I just downloaded SpyBlaster 4.0 after removing the previous version SpyBlaster. Everything seemed fine until I tried to enable all protections. Protections were enabled for IE and Restricted Sites, but when it came to Mozilla Firefox Protection, I received an error and the program terminated. The error was: "Error: Access violation at 0x660E6B79 (tried to read from 0xB7D438Fb), program terminated." I never had any problems with the previous version. My laptop is running Windows XP with SP 2. I also have the latest version of Spybot S&D installed, AVG Antispyware 7.5, and Ad-Aware 2007.
