Sorry Kryptic but don't agree. Having 2 AV programs on a single PC - each will confuse the other. AND, I have to say that with any free software, you get what you pay for. Let's get down to what's gone wrong with Norton. It won't stop working without good reason. Have you had a recent crash? Try running SFC. If nothing then remove Norton completely using Add/remove programs, then make sure that ALL Norton folders are deleted, then re-install from scratch.
when I try to run any of the Norton software it staqrts the shuts it self down I have tried to unistall anv but it wont, I do not recall seeing any error messages. I downloaded the free avg as suggested but it will not install just freezes on the mmc.
When to use SYMClean Use SYMClean when all of the following criteria are met:
Leftover NSW files and registry entries appear to be contributing to NSW installation problems or other NSW problems. You already used the Windows Add/Remove Programs utility and verified that the utility does not resolve the problem. Note that SYMClean is not intended to be used in place of the Windows Add/Remove Programs utility. It is designed to be used when the Add/Remove Programs utility does not fully uninstall NSW.
If the problem is associated with a particular NSW component, you verified that SYMClean is designed to remove that component. If the component is not listed in the section "Products that SYMClean removes," then use a manual uninstallation method instead.
For information on manual uninstallations, read the document How to uninstall Norton SystemWorks manually.
