Microsoft Security Essentials is most used anti-virus

According to the latest reports, Microsoft Security Essentials is the most popular anti-virus application worldwide. Microsoft’s solution, which is free to all genuine Windows users, has taken the top spot in the second quarter of 2011, as reported by OPSWAT’s study (via Softpedia).

Microsoft Security Essentials was found running on 10.66% of the 43,000 computers that were tested by OPSWAT worldwide. This beats the second place getter by a small margin, which was Avira Antivir Personal with a 10.18% share; AVAST! Free Antivirus came third with 8.66%.

However, when looking at worldwide vendor market share, Microsoft comes in fourth with 11.24%, getting beaten by Avira (12.29%), AVAST Software (12.37%) and AVG Technologies (also 12.37%). This difference is due to other anti-virus distributors having more than one AV product available, allowing their multiple products to combine to achieve the highest vendor market share. It is still great to see Microsoft so high on this list despite having only one major security offering.

OPSWAT noted in their study that the market share gain of MSE “could be attributed to the distribution advantage that Microsoft Security Essentials holds due to the convenient installation through Windows Update and its smooth integration with the popular IE browser.” It is also no doubt due to the fact that Microsoft Security Essentials is a free anti-virus solution, and while other free solutions do take the top spots, it certainly helps in the rankings.

Microsoft Security Essentials is currently at version 2.0, and has been available as a basic/entry-level anti-virus software since its launch in 2009. Since the launch, Microsoft stated that it has passed the 30 million download mark in late 2010.

As a free "just consider it part of the OS" solution, MSE is great. But I'm just glad stupid Comcast offers Norton 360 5.0 for free, it's amazing as far as features (AND yes performance!) go.

MSE had issues on a few computers I installed it on so I went to Avast which is still running great for me. But yes MSE is pretty much set in optional for windows updates if you don't have a AV installed which shouldn't be.

MSE is part of my standard clean install routine nowadays. People can accuse it of being thrust on users all they want, but people say a lot of stupid things. The reality is simple: on Vista/7, MSE is one of the (if not the one and only) lightest AV solutions available to users. It installs cleanly, it runs cleanly, it doesn't pop up at you constantly, and it feels like it just plain belongs in the OS.

It's not the end-all-be-all malware solution, but as a foundation for system security, Microsoft has accomplished something great, and the only reason I can think of for people to hate on it is some weird, childish desire to hate on anything Microsoft does.

Works for me...

Of course only a fool would not run a second scanner once a fornight. I use Malwarebytes. For added security I run a hosts file.

And it is free from the makers of the OS as it should be since the malware problems are inherently theirs


Folks just remember, MSE is an ENTRY LEVEL, again an ENTRY LEVEL AV. However, for such an ENTRY LEVEL AV. The most important thing is that it can detect the threats , and it works for most people.

In addtion, you have to question how you surf the Internet because once you start going to shady sites, that is when you usually get all of the infections from malware and viruses.

Should have said "However, for such an ENTRY LEVEL AV, it does it job fairly well.

Sentence Fragment is a sentence fragment...... <loop>

AV Test provides a good report on many AV software programs and MSE is 'average' at what it does. Nor more no less. In this day-and-age I don't need an 'average' performer. I have Norton 360 free via Comcast and its amazing with a very small footprint.

I use MSE for several reasons.

* It's free
* Updated easily (click "update"... wait... done)
* And it's lightweight.
* No idiotic functions and/or settings.

I'll stick to Kaspersky Internet Security which is by far a superior product to MSE, and free to all Barclays account holders.

I find it hard to believe that AVAST Software lost around 4 points of market share since the last OPSWAT study... which would equate to losing around 5 million active users (currently at around 130 million)... which has not happened, at least from where I sit at AVAST HQ in Prague.

A user base can be counted in two main ways: number of registrations (people who have both downloaded AND registered the product), and number of active users (people who receive virus database updates at least 1x every few weeks).

AVAST lists both user counts here, updated automatically (daily, I think): http://www.avast.com/about#tab4

No one here thinks it's ironic that Microsoft had to form a new team to write a AV application to protect the OS they can't seem secure from threats?

This is the case of the Fox guarding the hen house.

Just curious how much faith you would put into them if you were a major decision maker and if your ass was on the line, would you select the ISA Firewall to protect your corporate assets and all your people from threats?

Ahh another person under the assumption that every OS out there is secure except for Windows. How refreshing.

And the only person making any assumptions is you my friend. I didn't say anything about other OS's.

Anyone who say MS forces you to use it. You must be those people who click without reading. Besides this is the best free antivirus out there currently. Not once did it ever ask you to buy a pro version to get a certain feature. Besides I'm a student. Pay for an antivirus is not an option for the moment

LOL certain sites rated/currently rate Norton and Kaspersky as the best AV out there .. Avast is highly rated, and at the same time NOD32 and MSE being rated the lowest ... in my 7 years of experience with Windows, i've faced gazillion problems with the 'best' rated av's and enjoyed/currently enjoying the best 'tension-free' time with the so called 'worst' rated av's .. i trust my own usage .. not some rating done by some standards which hardly reflect a daily users os usage.

More proof the average user is a moron. MSE is the pits. Simple principle of economics that no one can quite comprehend - There is no such thing as a free lunch. You always pay somewhere - whether it be the antivirus itself or in the cleanup because you opted to use the free crap that did nothing.
