Hello @Ayaan121
We are sorry that WebAdvisor creates a log file of a higher size.I would request you to uninstall WebAdvisor from Control Panel and also removing the Extension from the browsers. Reinstall WebAdvisor by following the Article below and then add the extension to the browsers. This should fix the issue and will make sure that latest version is being installed.
