Google Will Start Notifying Users with Malware

By Daniel Scocco

A couple of days ago Google announced that it will start notifying users of its search engines about possible infections of malware or trojans on their machines. Initially the effort will be focused on the DNSChanger trojan, but hopefully it will be extended to other malware.

DNSChanger is a Windows-based trojan which changes the registry containing the nameservers your computer uses to find websites. As a result you’ll type something on the browser and will be redirect to another website, possibly containing further malware.

In order to be notified about a possible infection all you need to do is to search on Google.com. Here’s how the warnings looks like:

If you are wondering why they don’t this more often, here’s why, according to a Google security engineer:

“In general we want to notify users [of malware infections] anytime we are capable of doing so, but the fact that we don’t do this more often is really just because it’s hard to come across cases where we can do it this accurately. In many cases we only have maybe a 90 percent confidence that someone is infected, and the false positive rate of 10 percent is simply too high to be feasible. But in this case we can be essentially certain that someone is infected.”

The site KrebsOnSecurity has a detailed piece on the matter. Here’s the link to the full article: Google to Warn 500,000+ of DNS Changer Infections.

    With malware, or of malware? Would seem a bit silly if they were warning uses of malware with their own malware.

    Heh, Google should be worried about their compromised search results first!

    I always track the spammiest keywords to see what people are up to, just last week a site about STARCRAFT was ranking in the top 10 for “buy cialis”… c’mon Google!

    Hi Daniel,

    Great share, I’ve been navigating the site.. you’ve got some really great blog tips.. & I think it’s a good idea that Google Notifies Users about Malware, the FBI should have done something as they control the DNS Servers but Thnx to Google for doing this.

    Thnx for sharing this info, much appreciated.

    Peace!

    It’s good if google can help prevent people from falling victim of this malwares.

    I suggest that they should overlook the 10% unsurelty and include an apology notification if someone does not inventually locate any malware .

    It could be like this
    “sorry but we thought we’ve just detected a malicious software that can be hazardous to you. We’re concerned about your safety,you may kindly progress safely and carefully”

    This is just my own example though.

    Any thing that helps keep computers safe from these horrible infections is good in my book. The only question in my mind is will people believe the alerts?

    A healthy ecosystem of different browsers and OS’s will go a long way to keep the infection rate down

    I think its a good initiative by Google. Atleast they’ll now not ban users without illustrating any proper cause of its.

  • Chris @ NPI

    I have my own “online protector”, Avast. And it’s better than Google.
    I totally agree with Gregory – Google should give us better search results, nad not unrelated, spammy results.
    BR, Chris

    Many of the malware and Trojans(backdoor) are loaded up through those false ” Your PC has been infected by!@#$%^” messages, where people panic and hit the ” Use our Antivirus now to remove threat” message….

    There are(have been) some real nasty ones out there….and yes, they screw up your Computers Registry which creates the redirects….

    From there, every time you do a Google(search) no matter what you type in(due to the redirects) you will end up on their dodgy sites…

    The question is that “Is Google as fast as antivirus to detect malware or viruses?”. I think Google should focus more on producing better search engine results which is pointed out by some comments here.
