Windows update problem

I recently had a run in with coolweb and have finally managed to remove the
little bugger. I am now having a problem running windows update. This is the
message I receive when I try to update, any ideas on how to rectify this
situation would be most appreciated:

To install items from Windows Update, you must be logged on as an
administrator or a member of the Administrators group. If your computer is
connected to a network, network policy settings may also prevent you from
completing this procedure.

Note If you are running a Windows 2000 (except DataCenter), Windows XP, or
Windows Server 2003 operating system, you can run the local administrator
account on your computer without having to log off and then log on again.

To run as the local administrator in Windows XP or Windows Server 2003:


Click Start, and then click All Programs (or right-click Windows Update if
it is available).
Right-click Windows Update.
Click Run as on the menu that appears.
Do one of the following:
Enter the password for the administrator.
Enter the user name, domain name, and password of a different user account
that has administrative permissions on this computer.

To run as the local administrator in Windows 2000:


Click Start, right-click Windows Update, and then click Run As on the menu
that appears.
Do one of the following:
Enter the password for the administrator.
Enter the user name, domain name, and password of a different user account
that has administrative permissions on this computer.

If the option to run as the local administrator is not available:


Click Start, right-click Windows Update, and then click Properties.
Click the Shortcut tab, and then select the Run as different user check box.
