TPF 5.5 Build 1332 This is the last release of TPF 5.5. It includes new system security protection which eliminates code injection into trusted applications. In simple terms no virus or trojan (if you let it run by mistake) would tell your Internet Explorer or ICQ or others to load malicious dll and sneak around your computer. When upgrading to this build make sure to have Forced proc/Thread Termination and System Low level API set to AskUser(or Prevent)/Monitor. In the fresh installation this policy is set on by default.
