Microsoft raced to fix an anti-virus program that targeted Google's Chrome browsing software as a malicious threat and kicked it off computers.

Microsoft said the case of mistaken coding identity lasted about three hours and affected about 3,000 users.

"An incorrect detection for PWS:Win32/Zbot was identified and as a result, Chrome was inadvertently blocked and in some cases removed from customers' PCs" (personal computers), Microsoft said at a malware protection Facebook page.

An update to free Microsoft Security Essentials anti-virus software had mistakenly targeted Chrome as a troublesome computer virus tailored to steal online banking information. Microsoft apologized for the error.

I guess Google is more gracious than me because I'd be calling in the lawyers. Restraint of trade, slander, compensation for damage to reputation etc. I must be in a bad mood and being petty but anything to bloody Microsoft's nose makes me happy.

Microsoft can't compete with other browsers so it resorts to less than ethical mean to stay in the race. I think they should get out of the browser business this year, and operating systems next year as a gift to humanity.

Yeah they backed out after 3 hours and 3,000 users affected. Sure looks intentional to me. Now let's get back to patenting touch screens and copywriting fruit, oh wait the Beatles beat us to the latter? Fuck it, we don't care. We'll steal from them just like we did from Xerox!

and for our next trick, watch as our antivirus software removes any trace of open office!

Crikey, Frank, and I thought I was in a bad mood. I don't give a rats arse if was intentional or not. You can bet if your fruity favorite Apple got a scratch the lawyers would briefed immediately. Huh .. maybe Google really do believe in the motto .. Do no evil. Shame the same can't be said of Microsoft and the poisonous fruit company.

So the courts are just an arena for making bank then? Of course intention, the response, and the damage (virtually none) matter. And yes, would Google be following your advice, they would be doing "evil" in the sense of their motto. Google is a good company. Microsoft has a spotted history. The rub with Apple is their deliberate cultivation of an anti-microsoft image while mimicking their business practices. It's quite hypocritical.

All big companies converge to the same approach with no mercy. For example, Google browser gets too hardwired into operating system via its Google updater service in the same way, like the MS IE browser. Once you install it, it's virtually impossible to get rid of it in standard uninstall way.

No wonder, MS handles it like the malware, especially when it comes from its biggest competition.

Microsoft can't compete with other browsers

It indeed can, but MS browers are accused and fined for tied sales (although MS provides it for free) and for "monopolistic behavior" - so that MS has been forced to retreat from the active development of his browser - every new feature is considered as a violation of "open" internet standards. We shouldn't forget, most of hypermodern HTML 5 features existed in MS IE 5.0 version before ten years already as a proprietary technologies (DirectAnimation and VML canvas).

Oh, that's what it means. Seriously, does anyone not know this?

The Democrats started the process. The Republicans under Bush immediately put a stop to it.
Of course, it's socialistic and egalitarian politics. When some company becomes successful at market, we will divide it. What such approach should be good for?

The operating system market is incomparable to the automobile market, because the individual cars don't need to share any data or components between them. The market of operating systems is characteristic with the fact, the computers need to share their data freely. With increasing of number of operating systems at the market the cost of their maintenance and development of mutual conversion bridges increases geometrically. Therefore it's a much cheaper to maintain only one operating system at the market and free market economy always converges the minimization of the production costs. This is why we have still just one operation system dominating at the PC and why this result is actually in good agreement with laissez-faire.

In addition, the time required for learning of some car doesn't depend on the type of car too much. Once you will learn the driving of some car, the learning of the usage of another car is way faster.

At the case of operation system market the things aren't so simple. The time required for effective learning of operational system is considerable part of TCO (total cost of ownership). But the learning of one operational system will not help you in learning of the another system too much - on the contrary. Many people have substantial problems just with switching of keyboard and mouse habits between Windows and Mac-OS. For many people the learning of more than single operation system is simply too time demanding and ineffective. This is another reason, why most of people don't want the another dominating operational system at the market too much.

Operating systems have much more in common than you think. Ubuntu is pretty easy to learn for people who have used windows.

Holy crap this site is flooded with insanity and conspiracy theorists...

Lets do a little math okay?

30 MILLION chrome browser users...
3,000 affected computers.

Less than 0.01% of the Chrome user's browsers were affected.

I can see how it could happen, Chrome is a BROWSER. Browsers are capable of opening network connections, downloading, installing, checking remote servers and a lot more. It could have happened to any company that deals in anti-virus software.

Also, the end user chose to use M$ tools to scan their computers, it wasn't forced upon them.

Glad we can all use a little rationality now and again to draw logical conclusions. If Microsoft WANTED to damage Chrome users, don't you think they could be a little more... damaging?...

Not to mention outright attacking Google on purpose would be detrimental for their stock.

All this M$ bashing is in poor taste, Bill Gates does amazing things for people (go look where he gives away his money to and what it helps.)
