I am using the new Avast 7 browser plugin excursively for the phishing filter so I have "Enable WebRep" option unchecked. For the most part Avast honors the setting preference and does not display the WebRep ratings for google searches.
However, it seems once and a while the plugin will not honor my preference and starts displaying the Webrep ratings even when I have the "Enable WebRep" unchecked. Then I would have to go through Avast and uninstall and reinstall the browser plugin then the plugin works correctly.
I wish I could have a surefire way to repeat the scenario when browser plugins does not honor the settings preference, but I can't. I just wanted to report a potential problem to any developers.
