Hello,
if there are frequent popups from Web Shield, it is because a browser is trying to access a malicious website all the time. This may be triggered by some of the displayed web pages, one of the browser plugins, or it can happen when the user is typing into the URL bar on the top (browsers are trying to be smart and are preloading previously accessed web pages during this). This can usually be fixed by clearing browsing caches and history.
Saying this, we are now in process of implementing an option to silence these popups for a specific web page while keeping blocking it, as the current state is not ideal.
Kind regards,
Ondrej Kolacek
