I will do some research tomorrow & probably submit a feedback-or-two to Microsoft about the subject, then update this item with the reference/s. Either Microsoft needs to make a major change to the previously-mentioned URLs or needs to add the MSE definition updates to the Microsoft Download Center at. In the past, when Microsoft Update site was down, I have gone to the previously-identified site and downloaded an update as an alternative.

It also means the people without an internet connection do not have any source for an update, current MSE definition file…Microsoft has made a change and caused a problem. Signature File (Update Only) for 64-bit Windows system (about 13.7MB)įor the signature update links to be only the last base signature set of MSE definitions, and not the latest, daily MSE definitions is a problem for anyone going to that site as an alternate source. Signature File (Update Only) for 32-bit Windows system (about 13.4MB): However, if desired, MSE can be totally reloaded each time, but the definition file shall be the same until the applicable update file has been downloaded and applied. Rather than having to download the nearly 53MB installation file/s listed above, it should be easier and faster, in my opinion, to load only the definition files after MSE has been installed. The defintion files are normally updated a few times each day. The info below lists the URLs for the MSE definition (update) files.

The performance has been great…highly recommended, although the CPU load is a little heavy and the file size a little large, it is absolutely free for home use. Was a Beta Tester for Microsoft Security Essentials (MSEs), and, since issuance, have been using it on my XP computer and my Vista computer as a malware detector and alternate virus detector.
