Help menus will not open

[judieau]

In every program that I have (eg. Outlook Express, McAfee, Internet Explorer,
HP Printer) I try to open their Help menus.
I get a list of the items available but when I click on them, on the
righthand side a page comes up with the message *page not available* or
*action cancelled*.
I've been able to get into these help menus before without being connected
to the Internet so I don't understand what this problem is.
My problems started when my son downloaded a p2p program which I have since
deleted.
I have XP Home SP2 edition ~  it's also a brand new computer, a Dell Dimension 5150.

Can anyone help me please?

Thank you for your help Fed and I have downloaded all 'n sundry:)

When I run Ccleaner a message window comes up with *this process will permanently delete files from your system*.
Is this ok as I was a bit wary of going ahead?

I know it's a leap of faith the first time but I've never experienced a problem & never heard of anyone else having a problem with ccleaner.
I do remember the first time I ran it I did a gulp when I pushed the button too.
Go for it!
