Using Spybot 1.6.2 on Win 7 Pro 64-bit with FF 3.6.10 and immunization does not work at all. Running Spybot as Admin. I have searched to forum and see similar symptoms but none of the posts here refer explicitly to Win7Pro 64bit. I am also running Kapersky Internet Security 220.127.116.110 with Spybot as a whitelisted application.
FF is my default browser but the immunize function is failing for all protections for FF, IE8 32/64-bit, and IE8 64-bit browsers.
Other features of Spybot 1.6.2 work fine in this configuration.
