Unable to download anything

[Guest]

I have been unable to download any file from any website. I receive a message
on IE7 that Internet Explorer was not able to open this internet site . The
requested site is either unavailable or cannot be found. It hangs on Firefox.
The latest was after installing Windows defender, I received this error
message after it was checking for updates: Error found: Code 0x80240022. I
couldn't find this error message on Microsoft's website. I am using Windows
XP SP2. I have checked my internet settings and downloading is enabled in
tools. I have also reset the settings, but that didn't work either. I did run
%systemroot%\Windowsupdate.log file and think I see problems, but have no
idea where to go from here.

Any ideas?
Thanks for any suggestions!

First, go to control panel--internet options and delete your temp internet
files and cookies. Then try. If still no go, what firewall are you using?

I have deleted files and cookies. I have also deleted the temporary folder
and it did not improve.

so using what I have.

Disable your firewall and your current virus protection, see what
happens.

I have disabled the firewall and do not have any virus protection installed.

You might be missing a plug in. I don't know which one.
