Internet Explorer blocks 99% malware attacks; 5X more than other browsers!

With one third of internet users in Asia-Pacific alone becoming victims of threats like malware, the need for online security is more relevant than ever. To address these online concerns, Microsoft created their latest browser Internet Explorer 9, which provides a safe, secure yet beautiful and speedy browsing experience.

Today, NSS Labs released two reports which show that SmartScreen feature in Internet Explorer continues to offer industry leading protection against socially engineered malware.

As per the report “Internet Explorer 9 blocks an exceptional 99% malware. 96% of the live threats were caught with SmartScreen URL reputation in IE9, and an additional 3.2% with Application Reputation.”

What’s more, since the October 2010 NSS report, the average time taken by SmartScreen filter to block a threat has gotten 28% faster, if Application Reputation is considered, then the average time has improved by 85%. The graph below compares the test results from various browsers and shows that Internet Explorer blocks 5X more malware than competitive browsers.

The other reports looked at socially engineered malware targeted towards people living in Asia Pacific region and in Europe.

As you can see below, in each region the results remained consistent – Internet Explorer 9 maintains a lead in protecting users from live threats.

It is no surprise that a browser is the first line of defense against attacks from the web and it plays an important role to help keep you safe online. Internet Explorer is designed with your security and privacy in mind. The new browser has a robust set of built-in security, privacy, and reliability technologies that helps keep consumers safe and their browsing experience virtually uninterrupted. With IE9, Microsoft has introduced new features and functionalities like Tracking Protection, Tracking Protection Lists, ActiveX Filtering to name a few.

IE9 makes browsing the web even safer & protected experience from here on!

Internet Explorer 9 is in my opinion truly fast and secure, but suffers from an image problem. It is no longer ‘in’ to use it, especially among the younger netizens. All the problems being attributed to it belong to the IE6 era and are no longer applicable to IE9. Yet IE9 carries the baggage.

    It needs an ad blocker like AdBlockPlus. That’s why people use other browsers.

  2. Hi, Maybe you missed it but IE9 has Tracking protection Lists.

    not the same thing

    I’d be curious to see how Firefox 6 (and 7, when it releases in a few weeks) compare to IE 9.

    Maybe so, but IE9 is 10 times more agravating aggravating to use than Firefox or Chrome. Every time I am forced to use IE on another person’s PC I get totally turned off by all the hoops I have to jump through to do simple surfing.
    I have added my own protection in the form of add-ons, A-V software, and a firewall. None of these get in the way of usage.

    Did you do your comparison with a PC outfitted with good A-V and firewall and with browser add-ons that offer personal protection? NO! So comparing just plain browsers is misleading and you should be ashamed for putting out your information this way just for sensation sake.

    IE SUCKS and always will.

  6. I have installed and use all browsers. This includes IE9, FF6, Chrome13, Opera11 on my Windows 7 x64 with NOD32, and I enjoy browsing on all. I used to use Maxthon as my default browser earlier, but now I actually enjoy using IE9 because of its speed in loading and rendering web pages.

    The ‘IE sux – XYZ browser rulz’ statement may be a bit worn-out these days. As I said IE9 does carry the IE6 baggage. Nevertheless, it is always a good idea that one should use the browser which you are comfortable with.

    This study is a fact (and not sensationalism) – it is carried out by NSS Labs. Feel free to reject its findings if you find it unpalatable. 🙂

    The Tracking Protection list is a joke as an option for ad blocking. I suggest you try it along side FF w/Adblock Plus on a ad heavy site…I promise you will change your opinion.

    Are you really posting this BS again? NSS Labs results are inherently unreliable because their testing methods are flawed AND they can be bought.

    Their testing methods were designed to favor IE and MS provides NSS several million for the funding of these so-called “test”…so, naturally, they are going to declare IE the most secure browser. It’s what they were paid to do!

    Hell, if MS wants to pay me a few hundred thousand…I’ll start singing their praises too!

    …or, the dumb users, with no understanding of the connection between internet navigation and malware, are using Internet Explorer, meaning that they have a higher rate of trying to access really obviously threatening websites.

    The time has come for all IE bashers to get their head out of the sand and acknowledge that IE now is a far superior browsers. I know it is hard to accept this – but the faster you guys acknowledge it, the better it is for you. For the record, I was a Firefox user, but after IE9, I switched to IE and there has been no looking back!
