Hi, Sorry to start another thread, but search pulled up nothing recent that was the same question, so... I am going to remove ZA and replace it with Comodo. But I know that ZA is famous for lingering on the system after standard uninstall. The following ZA forum page: http://forum.zonelabs.org/zonelabs/board/message?board.id=AllowAccess&message.id=103 lists steps ostensibly to remove ZA completely. Registry editing scares me , so before I follow this list of steps, I wanted to ask the experts whether: (a) the steps all seem safe to you, and (b) whether this will indeed completely remove ZA from the system? Thanks. If my search missed a thread that covers a safer way to do the same thing, please just link me to it and then lock this thread. Edit: I just noticed that the ZA thread was from '06. In this other thread from this month: http://forum.zonelabs.org/zonelabs/board/message?board.id=inst&thread.id=84913 a user suggests using cpes_clean.exe Is that a complete tool as far as anyone knows, or would I still need to edit the registry as described in the older thread?? Also, does it matter whether I uninstall my AV (AVG 8) or ZA first?
