I'm using CCleaner version 3.16.1666.
Chrome's dns prefetch list (chrome://dns) does not get cleared.
Steps to reproduce:
1. Open Chrome and navigate to example.com.
2. Open chrome://dns to verify example.com entry is there.
3. Close Chrome and run CCleaner (all Chrome settings are checked for cleaning).
4. Open chrome://dns and example.com is still there.
If you clear browsing data via Chrome settings then the dns list gets cleared but it's not working through CCleaner.
