Microsoft has finally released its Security Essentials Antivirus software onto the world, and man, let there be rejoicing. I’m always a fan of free software, especially if it can handle an essential task well (and make no mistake, antivirus is absolutely essential) without being too intrusive. Microsoft Security Essentials is exactly this kind of software, surpassing most other freeware options while using only a fraction of the system resources others like Comodo and AVG do. As a bonus, MSSE is legal to use on any legitimate copy of Windows (therefore you should expect to have Window Genuine Advantage validate your PC’s OS).

So what exactly is Security Essentials? Well, to put it succinctly, MSSE is Microsoft’s former “Windows Live OneCare” software, minus the feature bloat. Gone are such things as online photo backup, central management of multiple copies on different computers (some people may miss this feature), preventing other programs from adding system tray icons and so on. What it does do, though, is provide a robust anti-malware package that’s very small (about an 8MB download, less than a third of alternatives such as AVG and Comodo), very light and very fast, with a small memory footprint. MSSE makes use of a derivative of the antimalware engine in MS’s Forefront security product (marketed at Enterprises…no, not the ones from Star Trek) and like you would imagine (yet dare not actually hope for) it never nags you for, well, anything. I suppose if you get a virus it’ll pop up an alert to tell you, but luckily enough I have yet to actually encounter anything malicious.

So if you’re using one of the bloated freeware packages out there or just wish you had something less intrusive on your system, I highly recommend you get your free copy of Microsoft Security Essentials. Just be sure to uninstall your other package right away!
