Angry Birds write their own anti-virus. Call it BitDefender. Sell it in Windows Store. But beware…

At the start of July, Microsoft proudly announced that it had reached an important milestone. 100,000 Windows 8 apps are available through its online marketplace, imaginatively titled “Windows Store”.

Of course, that’s only really a reason to celebrate if the apps are of good quality, from legitimate developers, and aren’t actually designed to con unsuspecting Windows 8 users out of their hard earned cash.

Sadly, there’s increasing evidence that the Windows Store has a worrying number of apps inside it which are designed to fleece unsuspecting users.

Here’s one example I found: BitDefender AntiVirus 2013.

This is not BitDefender

It’s not the *real* BitDefender AntiVirus 2013, of course, which is written by the Romanian software company Softwin, a respected member of the computer security industry.

No. This is “BitDefender AntiVirus 2013” as published by… Angry Birds Pro? and Kaspersky??

Angry Birds sell BitDefender?

It looks like someone has definitely got their Eastern European anti-virus vendors mixed-up, but more than that they’re claiming that a bunch of cartooning catapulting birds have written this anti-virus software app.

If you read all the small print (which is only revealed if you click the “Read more” link) you discover that the enterprising birds are charging you $4.99 for the pleasure of receiving a tutorial of how to use BitDefender AntiVirus 2013. But it’s easy to see how many users would be entirely duped and click the purchase button without realising they weren’t going to get an anti-virus app.

Clearly, something appears to have gone seriously wrong with the app-vetting procedures one hopes that Microsoft has in place to protect the Windows Store from fraudsters and opportunists.

And BitDefender aren’t the only ones to have their brand tarnished in the Windows Store.

As WinBeta reports, there are many tutorial and “How to use” apps in the Windows Store which pilfer the icons of the real products they are spoofing in the hope of making some quick cash.

Fake apps in the Windows Store

  1. It’s amusing to see them have two goes at “Cut the Rope” and “Temple Run” because the first time you could still see “How” in the title.

    May I simply say what a relief to discover someone that really understands what they're talking about on the net. You definitely realize how to bring an issue to light and make it important. More people really need to look at this and understand this side of your story. It's surprising you're not more popular given that you certainly have the gift.

    I have found some dubious apps in the Windows Store as well. See:

    and so forth. It appears Microsoft can still do a better job of acting as a gatekeeper for useless apps to its store.
