MS Security Essentials. Why is it free?

Hi.
While I can't answer your question about why they give it away, I can tell you I prefer it to Norton or AVG, and will never use anything else from now on.

There are several free AV programs out there. I prefer MSE to Norton; however, I don't use either of those.

Norton/Symantec AV is crap, and this is known by most computer hobbyists. Personally, I prefer Avira, since it's lightweight, thorough, and takes advantage of multiple cores. I switched after a suggestion from a friend after AVG totally overlooked 6 trojans on my old XP rig.

Why is this AV program free and how does it compare with Norton? I am looking for a catch here somewhere.

Why MSE?

Microsoft created MSE to address a very simple problem: Far too many PCs are unprotected with out-of-date anti-malware products. The company tells me there are a number of reasons for this. First, because many new PCs come with only time-limited security solutions, some users believe they're protected even though the initial subscription period may have ended. Some don't even activate the free, bundled solutions at all. Some--especially those in emerging markets--can't or won't pay for security suites, most of which need to be renewed every year.

Meanwhile, the security landscape is evolving. The impact and severity of security threats is increasing and is becoming more professional, with many malware outbreaks aimed specifically at financial fraud. Security software vendors are constantly adapting their products to meet these evolving needs, but these products are often complex and increasingly address a number of non-security tasks.

So MSE comes into this world and is designed to address the needs of users who are often not protected, for one reason or another. From a broad perspective, MSE works side-by-side with Microsoft's other security technologies, including those built into Windows and accessory products like the Malicious Software Removal Tool, but adding the crucial element of real time protection. It is based on the same trusted and well-regarded security engine that is used by Microsoft's Forefront line of products. It is incredibly easy to install and use. And, perhaps best of all, it is almost completely innocuous: Unlike the OneCare product it replaces, MSE is small and light and runs quietly in the background with a nary a chatty pop-up to be found. Finally, Microsoft has gotten client security right.

Oh, and it's absolutely free. As long as you have an activated, known-good (i.e. "Genuine") copy of Windows XP, Vista, or 7, you're good to go. Microsoft Security Essentials is just part of the package, a perk for users of Microsoft's modern Windows versions. And unlike other free solutions, Microsoft won't use MSE as a vehicle for up-sell. It just does what it does, and it will never prompt you to purchase a Pro version or whatever. There's no registration, no information collection, no annual worry. You install it and forget it, and it keeps you safe.
