You would not get that information not even if you could override Networkshield. I try to explain. Some at avast decide on ground of blacklisting or on a persistent spawn of specific malcode that there is reason to block an IP or IP-range for instance.
So far that's the funcionality of Avast and not to criticise.
How would you know?
That's one of the questions that Avast should be able to give an answer - in the sense of: alone from the warning itself should be determinable why the site was blocked. Inside the warning should be a link to the "protocol" of the day that the decision was taken to blacklist that site - with of course the reason why it was blacklisted. That can be some time ago - no prob. - but as it is now, you do not get ANY usable information than "Avast blocks this site (and as for you, you have to shut up and not to ask anything further)".
If you established that there should be no reason for that block
Sorry, no! I did only complain about the information policy of Avast. Again: that was also the reason that I first did not tell what site is concerned; it is just used as example here; nothing more! The question here is still the information policy of Avast and NOT that specific site!
because the malware has been closed, response is dead or new malware is not being spawned from there (VirusWatch list etc.) and see that there is also no more reason for that site to get re-infected (site server software does no longer give out full server version to the world, website software has been fully updated and patched and so not vulnerable to possible hacks, you could file a FP report and whenever it is found to be a real FP with a next update the block could have been lifted.
That would be a totally different story that is NOT topic here!
An override-feature of the Networkshield would be dangerous in the hands of the unaware and malversants alike. Who wants to play Russian Roulette?
That's clear and obvious - and that's why I propose to be able to override it only once without the necessity to disable the protection shield for that level - and OF COURSE that would mandatorily only be accessible by extended options/settings and of course default would be turned off!
