I have recently updated SPYBOT from v1.6 to V2, and even though its ran "as administrator" immunisation does not work with the section titled "Firefox: PE_C_PUBLIC (default)". I have uploaded a screenshot of the immunisation screen.
My OS is Vista V6.0.6002 (service pack2), I have AVG FRE 2013 running in the background, and the sdame problem occurs is AVG is disabled.
