Microsoft Security Essentials 2.0 upgrade

by

Microsoft Security Essentials is the antivirus program that I use and recommend (announced back in this post on October 25, 2010).  In the past few days, a new version of Microsoft Security Essentials has been released – version 2.0.  While it’s not mandatory, I do recommend that you get the new version (and in reality, you will probably end up getting it in a Windows update at some point anyway).

Microsoft Security Essentials 2.0Upgrading to Microsoft Security Essentials 2.0 is pretty straightforward.  You go and download the programs here, run the downloaded file to complete the installation, and then check your configuration to make sure everything is set up correctly.

There is a great new feature in version 2 – you can tell the program to only use a certain percentage of the computer’s resources when it’s doing a scan.  This means that you can set it to scan even during a time when you will be using the computer, and it will have little or no effect on your work.

For full step-by-step instructions on how to upgrade to Microsoft Security Essentials 2.0, and how to make sure it is configured properly, I have created an instructional video.  Watch the video here.

Scott,

After reading your recommendation for MSE vs. AVG 2011 and since my wife’s subscription to Webroot’s Anti-virus/anti-spyware was expiring, I downloaded and installed MSE. Immediately, her computer (with Win XP Pro, SP3) began to run slower than dirt. I eventually got smart and checked Processes in Task Manager and found MSE to be using nearly all resources whenever she tried to do anything, from opening Control Panel to running an online game.

Since I’ve subsequently read that the lock up problem with AVG 2011 affected only 64 bit boxes, I uninstalled MSE and installed AVG 2011. (To do so, I had to keep using task manager to close MSE as it wouldn’t let me get to Add-Remove Programs.) All now seems well with AVG.

Have you heard of others experiencing the slow down problem with MSE?

Jim – you are the first report I have had of this.

Scott,
The McAfee program that came with my computer 1 year ago is due to expire next month, so I’m intrigued about your MS Security Essentials recommendation. I checked my Windows 7 and see that it has “Windows Defender” (which is turned off because of McAfee). Is that the same as Security Essentials? Or should I ignore it and proceed with downloading Security Essentials (plus, of course the Malwarebytes)?

Mitch – Defender is actually one of the components of Microsoft Security Essentials. It focuses on spyware rather than viruses. For the full protection, I recommend MSE and the paid version of Malwarebytes.

I downloaded MS Security Essentials 2.0 and it scanned fine. But I noticed that my McAfee program, as well as its desktop icon are still here in the computer. I thought it’d be uninstalled as part of the process. Should I manually uninstall it now?

Yes, any other antivirus program needs to be manually uninstalled.
