Incompatability Symantec Drivers

Hi

Uninstall that old version of Norton Utilities and see if the message disapears, may also need to run the Norton Removal Tool HERE to clean up any reminents of the application.

Many of the older versions of applications dont work with Vista and above, so either get latest version that is compatible or a similar application/s with the features you like that where in Norton utils.

CCleaner will cover Junk Cleaning (temps etc), registry cleaning, secure deletion etc
Eusing Registry Defrag, does what it says, but to be honest, defragging the registry is a bit like swiming trough treacle, not going to make you go any quicker... the registry is one of those areas that is picked on in saying clean and defrag it for a speedy PC, yes while keeping it clean from old junk Key entries "may" spped it up a touch, but its not going to be noticable at all. I only clean the registry on my PC due to installing many many apps to test and removing them so have at times a dirty registry or when I advise a user to clean the registry as part fo troubleshooting.

Vista is also pretty good at optimising itself for most used applications (prefetch helps with this) its memory management is good (better than XP but not as good as Windows 7).

Both those applications I mention are free.

 

Hi

If the Norton Removal Tool didnt help (most cases it will) then you will have to pick the version of Norton you installed from this list HERE and follow the instructions to manually uninstall.
