We wanted to block all web ads and webroot helped to do this, but we had an issue with google searches having their ads at the top and customers clicking ads to legitimate sites and them getting blocked.
I had a quick search around but wasn't able to find a work around to either hide those ads or allow webroot to pass them through.
I did a little testing and found a way to keep blocking web ads but allow access to the google ads (purely for customer ease). This was to create a whitelist for googleadservices.com in the GSM Overrides.
Hopefully this helps someone else work around this.
