Hi Wolf
Ignore what the trend IT support have responded to you in their post below. If you read my earlier post you'll u/stand why.
After months of researching the issue and fiddling around and doing their job I think I may have found the solution to the pop up blocker problem.
Open the main console, select family icon , parental control opens up, click configure.
Now depending on how you have setup this section you may need to configure each account (if you have children accounts setup, you may want to keep their configuration based on age restrictions so inappropriate content is automatically blocked). This of course will continue to show the pop ups when they are logged in.
If you have your account (and this maybe the only account you have for everyone) setup with an age restriction setting, then you need to change it to CUSTOM. This is where I think the problem is.
Firstly, if your name is not showing in the parental controls window select manage accounts. Scroll down, find your name / account on this list and tick the box. When you return to the parental control window click WEBSITE FILTER. In here, where it says select an age, (this is the age restriction setting) select CUSTOM.
In here the only boxes I have ticked are pornography, illegal/questionable, violence/hate/racism and gambling. So far, the pop up has not reappeared. You can always try to add back one option at a time to get more security. I haven't tried that yet, just enjoying the NO popups atm.
Let me know if you need more info and especially let me know if it works.
Thanks Trend Micro !!
