The Internet is a wondrous thing but along with that there are many dangers. Be careful what you click on, remember there is no such thing as a free lunch, nothing is really free, more likely you will just get a virus or a Trojan. When something offers to speed up your PC it usually does the opposite and ends up costing you money. Never giveaway account details, usernames and passwords. And always be wary of emails asking for personal information.
