"NetBlockade"
I am now experiencing similar problems with "NetBlockade", but curiously only from this morning when I went online and started up Safari. Several months ago I downloaded a demo version of Internet Cleanup from SmithMicro, but in the event I decided against purchasing the full app. Since then, every single time that I log in, I've had to put up with a message along the lines of "Demo version of IC has expired -purchase full version of Network SpyAlert Protection ..." it is driving me MAD! and I've done everything I can think of to get rid this problem, eg I've trashed all remnants of the demo app in my Apps Folder; I've downloaded, and tried to sort out this problem with AppZapper (which apparently can't find anything left to "zap"); I've seen nothing to get rid of in "LogIn/ Startup Items" etc, etc; and I've redownloaded the demo version of IC with a view to "zap" it out of existence with "AppZapper" - result ultimately that I couldn't empty the Trash because Internet Cleanup "was still open"!!!!!
And I've also e-mailed Allume Systems/Smith Micro to advise them of the problem, and asked for guidance - NO REPLY after 3 weeks. Now today, out of the blue I find that sites I try to visit via Google are suddenly unavailable because of "NetBlockade" (as far as I am aware, this never happened before this morning, but happened all the time today): please, if anyone has any ideas as to what I can do, can they let me know: eg, do I now have to buy a new Mac (or possibly upgrade to Leopard?) to get rid of this awful "infection" caused by SmithMicro (for what else could you call it?)
