There's really no question what the most popular, free antivirus program for Windows is here at Download Squad. You, our readers, make it pretty clear whenever we post about the topic that Microsoft Security Essentials is at the top of the heap -- and we tend to agree. With detection rates every bit as good as some competing paid products (and better than many), MSE might just be the best piece of free software Microsoft has ever released. And it's just gotten better, with the official arrival of Security Essentials 2. The upgrade adds several key improvements, not the least of which is a heuristic scanning engine. One of the big knocks against its predecessor was that MSE's protection relied too heavily upon definitions -- and in today's ever-changing threat landscape, definitions just aren't enough. Still, I never had a single machine at home become infected while running MSE 1, so now that version 2 includes heuristic kung-fu I'm even less concerned about the safety of my Windows PCs.
MSE 2 also offers improved defense by better integrating with existing Windows features. The updated app adds muscle to the Windows Firewall and Internet Explorer to offer increased protection against network and Web-based threats. There's also a new network inspection feature which uses the Windows Filtering Platform in Vista and Windows 7 -- XP users won't benefit from this feature, obviously.
If you're already running MSE, check your update tab for an upgrade notification -- your system tray icon may also be orange if the update is available. You can also download Security Essentials 2 manually from this page and install over the old version.

Mozilla doesn't support the proprietary H.264 video format in Firefox, but Microsoft does. While Mozilla has been pushing open-source WebM as the format of choice for HTML5 video tags (with Google's help), Microsoft has released a new plug-in that lets Firefox take advantage of Windows 7's native H.264 support. The plug-in looks for HTML5 video tags and passes the video to the Windows Media Player plug-in for playback.
The Mac App Store is coming next month, but Windows users have a similar store they can enjoy right now. AllMyApps has just launched in beta, and it's ready to help you find, install, and share loads of great free (and eventually paid) software. 
Over at ZDNet, Mary Jo Foley has been speculating about the future of Windows Phone 7. According to Foley, a major update is due around Jan/Feb 2011, adding copy/paste functionality and two major browsing enhancements: HTML 5 support and a Silverlight plug-in. Foley also wonders whether enterprise tweaks might be part of the game plan as well. Microsoft, of course, doesn't comment on rumors -- so we'll have to wait for someone to score some hands-on time with the WP7 update.
At long last, Microsoft has given plug-ins for Windows Live apps their own home. You'll now find enhancements for Photo Gallery, Movie Maker, and Live Writer at plugins.live.com -- rather than at gallery.live.com, where they were nestled in amongst the sidebar and sideshow gadgets.
If you weren't aware, it's impossible to take screenshots with Windows Phone 7. Perhaps once it's rooted we'll be able to -- but until then, screenshotting apps for reviews is laborious -- you have to take a photo of the screen -- and the quality is inevitably low.\ABS\Auto Blog Samurai\data\Getting older programs to run on Windows XP\microsoft\digg.gif)
