Sometimes after the removal of Norton antivirus from Symantec and after the computer restart, some records may still remain in the system registry and prevent a Kaspersky Lab product from installation. That is why it is important to uninstall Norton antivirus before installing a Kaspersky Lab product. In order to fully uninstall Norton antivirus and its records from the system registry, use the following resolutions:
When uninstalling via Windows standard tools some files and folders of the previously installed antivirus programs may still reside in the system; that is why you are recommended to check the Program Files folder. If the Program Files folder contains any subfolders or files of the antivirus programs installed earlier, you are recommended to remove them. Then, try to install a Kaspersky Lab product once again.
In order to fully uninstall Norton antivirus, you can use Norton Removal Tool by Symantec (NORTON REMOVAL TOOL (С) Symantec Corporation. Distributed under the terms of the NORTON Software Tool Usage Agreement). See how to download a file:
Try to install your Kaspersky Lab product once again after Norton antivirus is uninstalled.
If all remains of your previous anti-virus software were removed, or you have not had any anti-virus software installed on your computer, but you cannot install a Kaspersky Lab product, then create a request to Kaspersky Lab Technical Support via the My Kaspersky Account service. Attach to your request a report of the Getsysteminfo tool. In the request, give detailed description of the problem and the actions necessary to reproduce the problem.
