Does anybody know if the handle leak with RTVSCan.exe problem has been solved? I am having the same issue on Windows 7 64bit. Here is the Event Viewer log:
_____________________________________________________________________________________________________________________________________
Windows detected your registry file is still in use by other applications or services. The file will be unloaded now. The applications or services that hold your registry file may not function properly afterwards.

It looks like the Symantec driver is leaking memory...
