No, it won't work cause the key logger saves the key strokes into a text file that is TOTALLY independent of the web browser. This file is stored at some location on the hard disk that no other program can find (except, of course, the key logger). Clearing the cache does not clear that text file since the browser does not even know of its existence. Also, formatting c: maybe work on some less sophisticated key loggers, but other actually have the ability to stream the text to another IP address or email. This means that whatever you type on the computer gets saved into a file and every five minutes or so, the program sends the text file to the thieve's computer or the thieve's email and this is repeated every five minutes.
