Do not use internet and move to other planet, so the FBI could not find you?
OR destroy your hard disk, put it into shredder or foundry.
Use data scrubber software may help http://www.summitcn.com/hdscrub.html

And i don't know if Malaysia's ISP got implement Data Retention or not. http://en.wikipedia.org/wiki/Telecommunica..._data_retention
And ohh, Google will save your search history by default, https://history.google.com/history/ can be turned of, fortunately.

I don't thinks they can delete permanently.
Even you disk is broken, its data can be restore, not to say that google or other internent company may store your data.

Normally clear your browser history and cooikes would be enough safe.
Go to browser setting, find privacy option, clear hisotry and cookies manually.
You can also use some free decent clean software to do this.
