Solving problems with protocol filtering
If you experience problems with your browser or email client, the first step is to determine if protocol filtering is responsible. To do that, try temporarily disabling application protocol filtering in the advanced setup (remember to turn it back on after you're finished, otherwise your browser and email client will remain unprotected). If your problem disappears after turning it off, here is a list of common problems and a way to solve them:
Update or secure communication problems
If your application complains about the inability to update or that a communication channel is not secure:
•If you have SSL protocol filtering enabled, try temporarily turning it off. If that helps, you can keep using SSL filtering and make the update work by excluding the problematic communication:
•If the application in question is not a browser or email client, you can completely exclude it from protocol filtering (doing this for browser or email client would leave you exposed). Any application that had its communication filtered in the past should already be in the list provided to you when adding exception, so manually adding one shouldn't be necessary.
Problem accessing a device on your network
If you are unable to use any functionality of a device on your network (this could mean opening a webpage of your webcam or playing video on a home media player), try adding its IPv4 and IPv6 addresses to the list of excluded addresses.
Problems with a particular website
You can exclude specific websites from protocol filtering using URL address management. For example if you can't access https://www.gmail.com/intl/en/mail/help/about.html, try adding *gmail.com* to the list of excluded addresses.
Error "Some of the applications capable of importing the root certificate are still running“
When you enable SSL protocol filtering, ESET Smart Security Premium makes sure that installed applications trust the way it filters SSL protocol by importing a certificate to their certificate store. For some applications this is not possible while they are running. This includes Firefox and Opera. Make sure none of them are running (the best way to do this is to open Task Manager and make sure there is no firefox.exe or opera.exe under Processes tab), then hit retry.
Error about untrusted issuer or invalid signature
This most likely means that the import described above failed. First make sure that none of the mentioned applications are running. Then disable SSL protocol filtering and enable it back on. This reruns the import.
