Microsoft Security Essentials is a much better choice among freeware AV packages. You would have noticed, that it updates its virus definitions on first launch and it could be a bit problem on a PC, which is not connected to Internet. But you can download its offline updates appropriate for your version of Windows.

You can download the Microsoft Security Essentials from here. Microsoft Security Essentials v2.1

How To:

1. Download the latest virus and anti-malware definition update files.

2. The update files are executable files and can be installed easily without much interaction.

To verify the status MSE: Open Microsoft Security Essentials, click Update, and then see the virus and anti-malware definitions status.

    that’s weird.. you said you have a 64bit OS but the error message looks for a valid 32bit app? hmmn.. is it possible to install a 32bit mse in a 64bit OS, then running it under compatibility options?

    for me, i’ll download the latest mse 64bit installer, uninstall the one presently installed, then install the one that’s just downloaded earlier..

    then: <<<64 bit manual update
