  2. Help! Win 7 and old chipset.

    I'm trying to help out a friend and have loaded win 7 on their pc. But as it's a skt 939 board with the nForce4 chipset, the drivers are not compatable. Specifically for the audio chipset and ethernet.

    What solutions can you guys suggest? And no, can't reinstall xp as it was completely trashed by viruses and the guy who built the pc for her never gave her the license code.

    Q? Why would you scan with Real Time Protection turned off? If you had to do that to run the scan then MSE is evidently not working properly . I used MSE for years on XP, Vista and Win 7 and never turned RTP off.



    Have you uninstalled/reinstalled MSE?



    I usually scanned with a third party on demand scanner (Emsisoft, Kaspersky, Malwarebytes, etc) about once a month to see if MSE had missed anything.



    Presume you have scanned for malware? List
    of Malware Removal Tools




    Note that Windows Defender on Win 7 is an anti spyware program only. It is not a comprehensive antivirus program. It should have been disabled automatically upon the install of MSE. Suggest you disable it.



    Remnants of other AV products sometimes will cause the issue you are describing. Did you run the removal tools for any antivirus program that was ever installed on the computer? Avast? AVG, McAfee, Norton, Spybot, etc. See List of
    anti-malware product removal tools




    If you have not done so you may want to review Microsoft
    Security Essentials Installation Checklist
    and MSE
    Consolidated FAQ




    If the above suggestions do not help or are not applicable to your situation, you may need to uninstall/reinstall MSE.

    You should be able to remove MSE from Control Panel. Any problems uninstalling see Uninstalling
    Microsoft Security Essentials


    Recommend you restart the computer to ensure the uninstall is complete.

    You can download a new MSE Installation File from http://windows.microsoft.com/en-us/windows/security-essentials-all-versions



    If the issue continues recommend you uninstall MSE and install a different AV program. There are a number of viable free and paid programs available – take your pick.

    MS Security Essentials


    WInX comes with Defender, but I prefer Security Essentials. Is there a way to upgrade to MS Security Essentials?
