Virus definitions are shared among all the key products Microsoft provides, including OneCare, Windows Defender, and Forefront. Under the hood, MSE uses the Malware Protection Engine, same as the Forefront Client Security product. (For larger organizations, Microsoft recommends the use of its Forefront products.) MSE provides real-time protection for home PCs, although Microsoft is promising that enterprise support for small business is on the way.

So far the tests have come back clean.īut by living on the edge, it will only be a matter of time before I pick something up - which is why I was interested in Microsoft's recent release of the second version of OneCare's successor, Microsoft Security Essentials (MSE).

But when it came to antivirus protection, I either went with no protection (which isn't a big deal because Windows 7 is so locked down that I don't see anything bypassing my superfast UAC prompt skills), AVG free antivirus protection, or - for those times when I thought that maybe, possibly, I picked something up - the online Trend Micro House Call scan. Windows Defender, however, as an antispyware tool has gained my trust over the years. Personally, I didn't like Microsoft's Live OneCare security software every time I worked with it on someone's computer, there was a problem of some sort.
