Avoid this like the plague that it is. It is more of a “How To” for particularly stupid script kiddies than a guide to protecting yourself from keyloggers, etc.
A couple of “nice” touches…
– There are links to lots of suspicious s/w, including the recommendation to disable your anti-virus before running at least one of them.
– For anti-virus it recommends “Spyware Cease”. Norton SafeWeb sees that site as very dangerous – drive-by downloads and viruses.
Ashraf, protect your reputation and that of your site by removing this immediately. Ideally, you should email any users who signed up for this and warn them.
