Microsoft Security Essentials 2.0 Review
Low on options, high on protection
Microsoft didn’t even bother to announce a version upgrade from 1.0 to 2.0, and at a glance, you wouldn’t be able to tell the difference. But make no mistake, Microsoft’s team of mechanics tweaked the scan engine and made some other changes underneath the hood.

MSE provides a handful of options for scheduled scans, but doesn’t include the ability to set up two different types (Full and Quick) on different days.
Let’s talk performance. Last year’s version plodded through our files without any sense of urgency, and the speed didn’t pick up during subsequent scans. This time around, the scan engine didn’t waste time investigating clean files that hadn’t been altered. The result is that a laborious 27-minute scan was reduced to less than eight and a half minutes the second time around. Still not great, but MSE’s at least headed in the right direction.
MSE leaves a smaller footprint than an Oompa-Loompa. We recorded a boot penalty of just 10 seconds, and things only improved from there. Copying a 3GB collection of files to our local drive took the same amount of time with or without MSE installed, and memory usage increased only a few percentage points.
Version 2.0 manhandled our updated collection of malware and sailed through another round of testing from Virus Bulletin, earning its second consecutive VB100 award on the Windows 7 platform. And unlike before, version 2.0 keeps the Windows Firewall in check and alerts you if it’s turned off. We just wish there were more to play with. You won’t find nearly the same level of customization as a paid security suite. MSE lets you configure a scheduled scan, for example, but you can’t schedule a Quick scan one day and a Full scan on another. It’s also frustrating that you’re unable to pause scans, only cancel them outright.
With an improved scan engine and the same stellar protection as before, Microsoft Security Essentials is still the freebie AV app to beat.

First of all I would like to say that I really enjoy reading the Maximum PC magazine, and have subscribed to it for years now, and I’ve always found the articles to be insightful and helpful. So when your review of Microsoft Security Essentials was published in Maximum PC, I read it and thought it would be a good idea to install it on my machines, specifically Windows 7 PCs, which I did.
I first installed Microsoft Security Essentials on my wife’s machine. The install went well, with no issues, then about 3 months later some strange things started happening – there were more virus alerts and the situation finally culminated in Microsoft Security Essentials indicating that my machine was no longer running a genuine Windows Operating System, but a counterfeit OS. I tried, several times, to apply the key that I have with my Windows software that I bought separately, and it would not allow me to put the key in, but repeatedly asked me to buy a new copy of Windows. After a while the machine’s background went black and it kept giving me error messages, after which it started killing all the applications, and nothing could be started because Microsoft Security Essentials killed every application on the system. At this point, in sheer frustration, I wiped out the system and reloaded it from scratch, after which it seems to be working all right, but still not as well as before I installed Microsoft Security Essentials.
Before these problems began, I had also installed Microsoft Security Essentials on my daughter’s laptop, which is running on Windows 7 Professional, and has been with no problems until 3 days ago, when exact same thing began to happen to her machine. At this point, since this was an eMachines laptop, it had the original software installed on a separate partition, which I managed to wipe out out and reinstall the original configuration.
I am an IT professional, and I have never come across a situation like this, where a product actually runs amok and corrupts the OS key, and I strongly suggest that you investigate this software further before recommending it in a review. As a result of this, I am very disappointed in your magazine’s recommendation, and don’t intend to follow them again.
