I have Norton Anti-Virus 2013. I cannot update my ant-virus definition files. The updates download but will not install. Message just says Installation failed.
Hi, osubuckeye. Are you trying to update via Live Update ?
Also, have you tried a reboot, and see if the definitions will install, then ?
If none of this works, you may have a file corruption and the best way to fix this, is often by using the Norton Remove and Reinstall Tool.
Please note, if you elect to do this you will be updated to the latest version.
If you wish to stay with 2013, make sure you've unticked Automatic Download of new version, under Computer/Updates in the UI.
Here is the link for the Remove and Reinstall Tool. http://www.norton.com/nrnr
Please check yout system clock and make sure thre are no errors with the time. Do you still have a current subscription. Have you run live update manually? What operating system and system pack and is it 32 or 64 bit computer? Are you having any symptoms of malware on the computer as some malware will prevent your computer from working correcrly. How long are we talking about not being able to install virus definitions? We need some more background information before trying to reinstall the program. RhNKA.
