Reported issue & resolution:
I'm running ccleaner daily (or almost) and the following two files were deleted because of a rule named "chrome logs":
D:\Utilities\PortableApps\GoogleChromePortable\Data\profile\Default\IndexedDB\chrome-extension_apmmpaebfobifelkijhaljbmpcgbjbdo_0.indexeddb.leveldb|LOG|0|0|24
D:\Utilities\PortableApps\GoogleChromePortable\Data\profile\Default\IndexedDB\chrome-extension_apmmpaebfobifelkijhaljbmpcgbjbdo_0.indexeddb.leveldb|000003.log|0|0|24
I added them to exclusions and everything is fine, no more deletions
