problem

everytime I Scan my pc with norton system check its always appear problem like this :

Invalid ActiveX/COM Entries (2 problems)
The ActiveX/COM sections of your Windows Registrycontain one or more invalid entries. This can cause documents to open improperly, applications not to run, or your computer to crash.

1. Missing or invalid key:"PlayerFlameClass/shell/open/command"
The key, "PlayerFrameClass/shell/open/command", refer to an invalid command entry,"C:\WINDOWS\PLAY32.EXE%1"

2. Missing or invalid key: "ViewerFrameClass/shell/open/command"
The key, "ViewerFrameClass/shell/open/command", refer to an invalid command entry, "C:\WINDOWS\PLAY32.EXE%1"

I always choose to repair it....but still....always find the same problem when I do system check. I have no idea what to do now......my friend said just leave it like that if I got no problem with my pc.
