I don't know for sure, but I doubt it. What you can do, however, is to prevent your guest from visiting those sites in the first place and keep your guest from using CCleaner.
Put your guest on a limited or guest account, change permissions for CCleaner so that only you, the administrator can run it. Enable content blocking, put the illegal sites in the restricted zone of the browser, use the firewall to prevent connection with those sites or a combination.
If your account isn't password protected, put a password on it now. If it is password protected, change the password. Also, put a password on the Administrator account that shows up in Safe Mode and create a bios or boot-level password. You can read how to do this here: http://www.malwarehelp.org/Malware-Prevent...-Security1.html
This will keep your guest from bypassing the new restrictions.
Hope this helps,
