I'm using ZA Internet Security and it's suddenly developed a weird problem.
I've written a piece of software (Delphi) with uses WININET to access the internet and sends XML output to a secure URL, waits for a response, acts on it, sends results back, waits for response, acts on it, sends results back etc. until it either receives a success message or an error message. If the URL is unresolved it throws an error message dialog and resets, stopping it's internet access. If it does not get an appropriate response in the correct format it throws up an error dialog and resets - stopping it's internet access.
Now this software was written on this machine and tested on this machine all OK. It has been distributed to our customers and used successfully. Yet the other day I went to use it for our own live transmission and ZA has stopped it working. When testing, it successfully accessed the URL and swopped message pairs hundreds of times.
I ran it, filled in some needed data and clicked to start submitting data. ZA came up again with a repeat box and I clicked ALLOW and also remember this decision. The program started and then immediately announced it had finished the process correctly. It can't have done as it received no data back to act upon. I have also tried it with a deliberately busted URL and incorrect user ID and passwords and it still reports success. We have checked and checked and checked code and it is not supposed to do that. It is not supposed to be able to do that. The only thing that's causing it to behave this way is ZA. We've tried it on the same machine after turning off ZA (risky) and it works as it is supposed to do. On other machines with different firewalls it also works OK. So the only thing which is affecting it is ZA.
Now having gone through various other security software over the years, ZA was a breath of fresh air and we've had no problems with it - till now. If this problem can't be solved then I'll be uninstalling it and telling our customers to keep clear. If it used to work properly how come it doesn't all of a sudden? I've checked and checked all of ZA settings and given the program in question full trusted access according to program control - yet it is still behaving impossibly.
I don't understand how this can happen.
