Help Internet Security

Can you help me?
Trying to load Kaspersky 2009 security. It always comes back saying it has found AVG8 and I must remove this first.
I have tried everything to remove this. Have done a search in all my files. Computer says that there is no longer any AVG8 to be found , but I still can`t load my new security disc.

AVG8 has probably left some registry files behind.HKEY_LOCAL_MACHINE\Software\AVG
HKEY_CURRENT_USER\Software\AVGI think think those are the only important ones, there is some stuff in the CLASSES directory, but I've never really played in there before.Any particular reason you want to get rid of AVG?

Have had AVG for a long time. Did a scan and it came back with 3 viruses so thought I would try this, as I know others who use it and said they never have any problems.

Yes this has happened to me before. Kaspersky always saw AVG as installed, try running CCleaner.
