Is it important to uninstall old Norton to install the new version?
If you are thinking about installing the latest version of Norton on your device, then, first of all, you need to uninstall the previous version of it. It is so because there are some product versions that may not support the upgrading and they create interruptions in the downloading process of Norton antivirus.
You just need to remember, the new version will not be similar to the latest one so, you need to be a little calculative in installing the latest version of Norton setup. Also, make sure the latest version matches the device compatibility. Furthermore, uninstalling the temporary and junk files is also an important part of the process for successful completion of the same.
