I installed and ran C Cleaner last night, the results are great and my PC is a lot faster than it was.
When I restart the PC I get the Windows Installer box come up with "......Preparing to install" for a minute or so then the messsage "Norton Antivirus 2005 does not support the Repair feature, please unistall & restall".
I am not very technically minded so apologies if this is an obvious query, do I need to un & re install C Cleaner, or Norton? I am reluctant to un & re install Norton (firstly don't know how to!) and if so will I get this every time I run C Cleaner??
Yes, we pay annual subscription for our Norton Antivirus, the latest doesn't run out until mid-April.....so not sure why it is coming up with this message!!
If neither of these fix the issue, I'd follow Kens advice and remove Norton with the official uninstaller tool, then either reinstall Norton, or pick a new, free Antivirus. These are just as good, and sometimes better than commercial packages.
The version of Norton you have is very bloated, and sinks it's tentacles all over your PC. Norton 2005 was the package that came with my PC, and getting rid of it was one of my better moves. I now use Avast, and have done for a couple of years.
