If you are changing to a new antivirus product, you will need to uninstall the previous antivirus scanner first. For example, if you want to install Avast Antivirus Pro Crack but your old version of Avast already exists, you will have to uninstall the old version first and then you will be able to install the new version. After uninstalling, you must reboot your PC before installing the new scanner.
If you are simply upgrading the existing antivirus software to a newer version of the same product, there is no need to uninstall the older version first. However, if the new version is two or more versions newer than the old, then you will want to uninstall the old version before installing the new. Again, anytime you uninstall an existing antivirus product, be sure to reboot the computer before installing the new scanner.
