Why not use your obvious software skills to develop a program called "DiskWasher" This could be some simple program which enables one to clear out from one's hard disk all the old rubbish that accumulates. It is well known that, when one deletes some data, it is still on the hard drive. I am thinking particularly of web sites visited. It is too easy for a hacker to find out which web sites one has visited and send one loads of spam.
