You really need to find yor HP recovery CD, as it appears that you have been owned, and the only safe solution is to format and reinstall your system.

I assume that you registered your purchase with HP when you bought the machine so you can ask them to supply you with a new CD if you have actually lost it. You really ought to do that to deal with future problems that might arise.

I do not think that it is Zone Alarm that is stopping you from viewing web pages that sounds more like another problem..............what is the message that displays down the bottom.............something like page not found or DNS error?

Search this site for a thread about dell recovery cds, there was one quite recently, which will explain how to use it..............I do not see any legality problem, but it will tell you that it is not a Dell Computer. As long as you paid for the OS it is legal.

Cheers
