The following quote is from the CCleaner guide. When running CCleaner under normal deletion file does the following still apply. Or is it only under secure deletion file?
"Additionally your operating system records every visit to every website; every time you open a document, and a lot more. Do you want people to be able to find out this information?
Even if you don't mind other people knowing what websites you visit, your internet browser can save personal information about you, such as your name, address, date of birth, passwords and credit cards numbers. Luckily CCleaner will remove all of these!"
