If you want to expose a PC to the hazards of Myspace, Facebook, etc., do it with your own PC, not one belonging to someone else.
I am in the middle of removing yet another worm from someone's PC because they were too stupid to watch what they were clicking on in Facebook.
In addition you may like to know that I and about 100 other prople spent a day without Internet, email or corporate network because some stupid pillock couldn't be bothered with basic Internet security and connected an unprotected PC to our network, which he had managed to infect with equally iunjudicious surfing.
Rest assured: behaviour of the kind in which you are trying to indulge would be groungs for instant dismissal in many companies.
Grow up.
Get an education (Preferably one which includes something about Integrity)
If you want to put a PC at risk, do it with your own (And never do online banking again)
