Does CCleaner "overwrite" files?

CCleaner for Windows
1

Hi all:

I'm new to CCleaner. I'm wondering if CCleaner overwrites deleted temporary interfiles, etc. so that they can be undeleted. Webroot Window Washer has this feature and they call it "bleaching". Basically, files are overwritten with random characters a minimum of three times. Three times is apparently department of defense standards.

Does CCleaner do this automatically or is it a feature somewhere? I couldn't find anything about this on the website or user manual.

Thanks for any help.
