I bought PG a year or more ago and have had every faith in it since it seemed to catch or be configured to catch malware that cropped up. That is until I came across this link in Wilders where the Comodo people have discovered a new leaktest. I don't use IE so tests 1 & 3 did not concern me, but test 2 goes straight through PG. Of course if you did not allow the test suite to start in the first place you would be ok, but you cannot know if this process is hidden in an innocent appearing program that you try. First of all I tried out AntiHook and that stopped it dead but is adding another layer which I don't really want. Then I saw that SSM stops the process in the freeware version. In view of this I have uninstalled PG and switched over to SSM to see how it goes. A pity because I like PG but it no longer seems to do its job, and judging by other comments here there seems to be little input from DiamondCS now.
