  • XP - cannot install Service Pack 2 and 3 in order to install anti-virus protection.

    I need to install Service Pack 2 and 3, in order to install a virus program.  I currently do not have one, as my Norton Antivirus program should be uninstalled.  I can't get the Windows Update page to download.  Is there another way to get to this download?  I want to get do it as fast as possible, as I am currently without any virus/spyware protection.

    Thank you!!

    If SP2 to SP3, is not installed, you could not possibly have a functional application of the antivirus installed and missing a value of more than four years of critical security updates! It is not a chance in h * that SP2 & SP3 will install with your computer in its current state, Erica.
