Hello there, welcome to the Community!
There has been a change in the filter extensions in how to disable and remove them. Please see THIS KB Article for more information. You MIGHT be able to disable them yourself in the Browser settings, Extensions / Addons but you may need to follow the directions in the KB as well.
If I may ask, what browser are you using? I am getting reports from users of Chrome that they now have a slowdown in that browser only. If you have been using the Filter Extention all along, and only now are having issues with it and a slowdown, please submit a Trouble Ticket so that Webroot Support can gather information and submit it to the Dev's so that the issue will be fixed.
I hope this helps!
