Does CCleaner delete any traces of internet history on the whole computer?

[CountOlaf]

Hey,
So basically, to cut a long story short I have done some naughty stuff on my laptop and my dad has become very suspicious. He said he will get his extreme computer nerd friend to check my whole hard drive which will let gim see what I've been doing on the internet, even if i delete all my browsing history. Plus he said his friend would put monitoring devices on it, so I am very scared now. I download CCleaner and 'permanently' deleted all my internet history files from my computer, but i have a feeling that traces of them are still present there, so I am very scared now. Does CCleaner delete them from the hard drive? Does it mean they can't find my internet history or are there other ways that super computer nerds know?
Please reply ASAP, because I am REALLY REALLY SCARED!!!

Thanks,
The count

lol why would you dad do this and trust me he will be a happy man if he sees you've been looking at straight of age women, I am just picturing this now though your dad and his friend sat around your pc finding traces of deleted files and bam pops up all this gay porn...I imagine then he'd be pretty pissed off.
