Microsoft Security Essentials Picks Up Market Share

Microsoft Security Essentials Picks Up Market Share

Microsoft did its Windows customers a solid when it released its Microsoft Security Essentials (MSE) antivirus software as a free download. That in and of itself is nothing to write home about, but the program is actually good -- very good -- at detecting and neutralizing security threats, both in real-time and after they've already occurred. Reviews of MSE are typically positive, and that's not lost on Windows users.

According to a report published by OPSWAT, a software development company based in San Francisco, MSE is fast becoming one of the most popular antivirus programs out there. In terms of worldwide market share, MSE is the third most popular antivirus program with a 10.08 percent share, trailing AVG (10.96 percent), Avira (11.65 percent), and Avast (16.26 percent). MSE sits ahead of heavy hitting AV programs like ESET (10.06 percent), Symantec (9.97 percent), Kaspersky (7.75 percent), McAfee (4.74 percent), and several others, and also recorded the biggest market share gain of the bunch in the past year.


In North America, MSE is the second most preferred antivirus program with a 14.92 percent, a little more than a percentage point behind Symantec (16.09 percent).

"Symantec continues to lead the North American antivirus market at the beginning of 2012 with 16.09%, a slight decrease from their 16.65% in 2011," OPSWAT notes. "Microsoft leaped from fourth to second place in this year’s ranking with an increase from 9.94 to 14.92% over the last year."

Which antivirus program do you use?

I have been using MSE for about a year now. Works great from what I have seen and it has a fairly small footprint.

I've been using the free version of Avast, but after reading this article I'm thinking I might give MSE a spin.

Been using it for a year too and I really like it. It has a very small foot print and is so damn easy to use. I used to have Bitdefender and it go so bloated that navigating the menus just became a chore.

I use AVG and MSE, the two dont seem to have any conflict issues. I perfer MSE just because its lighter and seems to cause fewer slowdowns, but it has found and removed virus's just fine.

MSE and MalwareBytes Anti-Malware (paid version w/ real-time protection) is my go-to solution for me and my clients. Pretty lightweight in total and great overall protection.

I use Avast and MSE on different machines and I am very happy with both.

I have avast on all three computers and it's been great. When I first installed it on my sister's laptop it found a few trojans that were there while the free version of avg did nothing!!

I have been using MSE for over a year now and have had no problems at all.  Switched from NIS and glad I did, no more bloat.

I use AVAST and MSE on all of my PC's. No conflicts between them at all and they provide good overall protection for me for a great price. I also use Malwarebytes free version.

I like that these solutions are free and that they outclass paid solutions too.

I use MSE. I did use AVG before but I found it bloated and switched to MSE; glad to see it picking up market share.

I use ESET Smart Security 5 and really like it. But for friends who don't want to deal with configuration and monitoring their software, I usually put MSE or Avast on.

I love MSE!

By Microsoft, For Microsoft.

Totally free of the crap, bloatware and annoying buy/upgrade now notifications that come with other free (or trial) versions of Anti-Virus'

I've loaded MSE on every friends machine I've come across and those I've been asked to clean or repair in need of an Anti-Virus. A majority of my school district uses it on all its computers as well

The best anti-virus is still common sense and good web habits. I know people who do not use any antivirus of any sort and have done so for years (no I'm not that brave...)

These days there isn't much difference between free antivirus programs (in the premium suite market it may be a different story), but I agree with everyone who does not use AVG. Just pick one antivirus, and something like malwarebytes or spybot and you're fine.
