AVG Clear deletes all files associated with your AVG product from your computer, including registry items, installation files, user files, etc. AVG Clear is the last option to be used in case the AVG uninstall or repair installation process has failed repeatedly. All AVG user settings will be removed after the uninstall process is complete, as well as content from the Virus Vault and all other items related to AVG installation and use. You will be asked during the removal procedure to restart your computer. Therefore, please make sure to finish your work and save all important data prior to launching AVG Clear.
