I am using PG free and I tried the latest version ProcessGuard v3.3b3 for a while. Did not use it for long time but just want to mention few things, 1- A bug in settings is not fixed. See my thread please, https://www.wilderssecurity.com/showthread.php?t=123332 especially post no. 21, 22 and 23. I am rather disappointed. 2- Grossly there is no much increase in application execution control. I compared current version( not beta but I think in this regard both are same) with Antihook and I will say AH has more detailed rules. Just for an example, if i install a software on my PC( suppose its name AA), now this software AA tries to launch my browser to access internet, PG will ask for permission, if I permit and make it a rule, the rule will be generalized so that next time software AA can launch not only my browser but also any other application like outlook express etc without any warning from PG. On the otherhand, if I have AH, it will ask me for permission and if I permit and ask to make a rule, the rule will not be generalized. It will be rather specific, I mean next time this new software AA will be able to launch browser without any warning by AH but if it tries to launch some other application, AH will again ask a permission to do so with a new rule formation, and the process will be repeated again if AA tries to launch some other application and so on. I know this is only one aspect of the security offered by PG but I will really like it be more advanced in rules creation like AH. Please correct me if I am wrong anywhere. I am PG user and just intend to see improvement in it.
