First of all, what program AV.AM (s) do you use?  Some (actually several) disable Defender during installation and Defender should be left in the case, or it may cause conflicts, crashes, freezes and other problems.

If this is not the case, here is an article on how to enable Windows Defender when it will not start normally:http://support.microsoft.com/kb/555962.

    Hello

    Here are the different ways to reinstall vista

    Contact the computer manufacturer and ask them to send you to vista recovery disks to reinstall the operating system back as it was when you bought it

    they do it for a nominal cost of $

    also ask them if you have a recovery partition on your hard drive to get back to the way you bought

    you would normally press F8, F9, F10 or F11 or Alt + F10 or 0 to start to start the recovery process according to the manufacturer

    Ask them of the exact key sequence

    or borrow a vista microsoft dvd; not a HP, Acer recovery disk etc

    Make sure that you borrow the correct 32-bit or 64-bit microsoft dvd to your computer

    they contain all versions of vista

  • I can't update the Windows Defender definitions and get this message: the program can't check for definition updates. Error: Code 0xc8000408.

    Impossible to find info on what this means or what to do so I can again update in Windows Defender. This error message has begun to appear recently, or at least I think. I thought it was set to automatic update, but when I tried to do it manually because it says it's expired. Tried several times but get the same message every time.

    You are welcome. Your computer must NOT be connected to the internet or networks without a fully functional antivirus, completely update installed application. But first, let's take care of any Norton "leftovers"...

    1. download the Norton Removal Tool, save it to your desktop: ftp://ftp.symantec.com/public/english_us_canada/removal_tools/Norton_Removal_Tool.exe

    2. close all open applications (that is, anything with an icon on the taskbar).

    3. click right on the file saved in #1 above, and then select run as administrator to run the utility. DO TAP not your keyboard until the race ends, then restart.

    Now, you will need to download/install an antivirus application. While I do not recommend professionally AVG, you might find that AVG Free 9.0 more compatible if you choose a CUSTOM this time installation above and don't install NOT of Linkscanner Search-Shield, Active Surf-Shield, security or the email of crawl components toolbar.

    Why you don't need your anti-virus to scan your email
       http://thundercloud.NET/infoave/tutorials/email-scanning/index.htm

    Otherwise, I can recommend Microsoft Security Essentials*, Avira AntiVirand Avast (all free) and NOD32 and Kaspersky (not the suites 'internet security'). After you have installed your AV application selected, manually & repeatedly updated until you get one invites 'no more updates'.

    [Avoid Norton & McAfee IMHO applications.]

    =============================
    * Microsoft Security Essentials (MSE) includes components of antivirus and antispyware protection. The latter will replace (and must turn off automatically) Windows Defender in Vista.
