reboot your computer and then install AVG 8.5.
IF you should have "problems" uninstalling:
AVG Remover utility removes all parts of AVG installation on your computer, including registry items, installation and user files on your disk, etc. AVG Remover is the least option to be used in case the AVG uninstallation / repair installation process has failed repeatedly.
All AVG user settings will be removed after the uninstallation, as well as the Virus Vault content and other item related to AVG installation and use. During the removal procedure you will be asked to restart your computer. Therefore please make sure to finish your work and to save all important data prior to AVG Remover launch.
I plan to download AVG 8.5 to replace 7.5. Can I delete any 7.5 files or the whole 7.5 program? I would like to delete what I can to free up disk space. I have an older Dell and I am running out of disk space.
