There is a Symantec Temporary File folder located in C:\ProgramData\Symantec Temporary Files under the Windows 7 file structure. It would be nice to include this location to be cleaned by CCleaner.
CCleaner has an option to specify which files or folders/directories are to be cleaned as well. One can program which files or folders are to be cleaned. It's already in the program (v2.29) !!!! Search and you'll find the options.
