Fake Antivirus Android application discovered

AVAST virus lab analyst Filip Chytrý has discovered a fake Android Antivirus application impersonating avast! Free Mobile Security.  The malicious application called com.avastmenow has a user interface that looks very similar to the genuine one by AVAST Software. After the installation of the fake program, an icon with the text of PornHub is displayed to users.  The Trojan displays fake alert pop ups in an attempt to convince the user he is infected even when he is not. Users who download the fake application might end up with their Smartphone device blocked and be requested to pay 100$ to unlock the phone.

Our virus lab specialists are currently working on samples, so the AVAST virus database will be updated shortly. The goal is to protect all avast! Antivirus users and prevent them from downloading the malicious application. We will update our community on the progress here and on our social media channels.

Meanwhile we recommend all users to use trusted source and download avast! free Mobile Security only from here.

Lost or Stolen Smartphone: The Consequences are Bigger for Women Than for Men, Our Study Finds

shocked woman (1)Personal contacts, photos, videos, apps, emails, text messages — smartphones today contain a plethora of personal information, and the thought of losing or having a smartphone stolen is extremely worrisome to many people. Our security research team recently conducted a survey of 167,904 customers worldwide and found that consumers in the United States are among those most likely to lose or have their phone stolen. We then wondered, who is affected more by a stolen or lost cell phone in the US, men or women?

Men carry out more security sensitive transactions on their phones

Men in the US use their smartphones more often to take care of online banking, download apps, and believe it or not, shop more than women do. Women, on the other hand, use their smartphones more to text and to connect with friends on Facebook and other social networking platforms. Now, the logical conclusion would be that men are more at risk if they were to lose or get their cell phone stolen. You might think that online banking and credit card information stored in browsers and apps would be more appealing to smartphone thieves than personal information, status updates, and maybe even gossip.  But that is simply not the case.

avast! Mobile Premium: The Ultimate in Mobile Security

new AMSpost_img

More than 25 million Android smartphone and tablet users protect their precious devices with AVAST’s free security app. Today, we are happy to provide even more awesome features in our new premium version, avast! Mobile Premium.

The security of data on mobile devices is a growing concern. Over a quarter (26%) of mobile phone owners have lost their phone or had it stolen, and that means that photos, contacts, and personal information, and in a growing number of cases-  company data, is exposed to crooks. This data loss is exacerbated because nearly 50% of US smartphone owners do not back up their content.

avast! Mobile Premium can help you recover your lost phone and data with superior back-up and anti-theft technology.

Erect an invisible fence around your phone

Geo-Fencing is one of the clever anti-theft features of avast! Mobile Premium. You set up a perimeter, for example, around the coffee shop, and choose some actions like setting a loud alarm. If a sticky-fingered thief tries to take your phone outside of the perimeter when you are distracted by your mocha latte, the alarm goes off, or the phone is locked. Gotcha! Read more…

avast! Mobile Security gets Editors’ Choice Award from PC Magazine

pcmag_blogPC Magazine awarded avast! Mobile Security the Editors’ Choice Award for free Android security apps thanks to its “huge array of powerful tools and fine-grained controls.”

A major concern for smartphone owners is the increasing threat of malicious software targeting Android OS. Max Eddy, software analyst for PC Magazine, writes that, “avast! is well-positioned to guard against new threats that use novel attack vectors we’ve yet to imagine.”

Running quietly in the background, with no system slow-down or stuttering, “avast! will also keep an ever-vigilant eye on your device, warning you as soon as it detects something it doesn’t like,” he writes in his June 2013 review.

But these days, it’s more likely that you will fall victim to theft and loss instead of malware. Eddy explains, “In this department, avast! has an impressive slate of features and controls.”

In case your phone walks off somewhere, you can use the my.avast web portal where you can remotely locate, lock, or wipe your device, and set off the alarm. Eddy said, “I was particularly impressed that the alarm was not only loud, at 96 dB, but also highly illustrative. ‘This phone has been lost or stolen,’ said my S III, cycling between that phrase and what sounded like a Star Trek warning klaxon.”

Make sure you install avast! Mobile Security, the Editors’ Choice for free Android security suites, on your smartphone and tablet. It is available for free in the Google Play store.

Android:Obad – malware gets smarter – so does AVAST

det

If you had the privilege to meet Android:Obad, which Kaspersky earlier reported to be the “most sophisticated android malware,” you are in a real bad situation and this will probably be the moment to which you’ll be referring to in the future as “The time I learned the hard way what better-safe-than-sorry means.” A few days ago we identified a new variant of that threat. There is a chance you bumped into this bad guy before we started detecting it, because if our generic detections don’t catch the malware there is always a short delay before it gets to us. In most cases, it isn’t a problem to get rid of a malicious app – you just uninstall it after you find it. This time, that won’t work.

The problem we are facing here is called “Device administrator.” After you launch an app infected with Android:Obad, you will be asked to make the app the current device administrator, which will be only a few buttons away so it isn’t hard to do. After you do so, there is no way back because this piece of malware uses a previously unknown vulnerability which allows it to get deeper into the system and hide itself from the device administrator list – the only place you can manage device administrators. You won’t be also able to uninstall the app via Settings, because all the buttons will be grayed out and will not function.

Lucky for you, avast! Mobile Security will save you from doing a factory reset and losing your data, which certainly is one of the solutions. But don’t worry, you are safe with us. Read more…

Sneaky little bastard

It has been two or three months since I last blogged about Android malware. But that definitely doesn’t mean there aren’t any new threats. There are plenty! Here are two quick comparisons from the last two years: Growth of the malware problem of the platform in January 2012 compared with January 2013 is far from the ‘normal’ growth of other platforms. According to our statistics, it’s something around +850 percent! Add another year for an even more insane comparison – the growth from January 2011 to January 2013 gives us +3150 percent! The Android platform is definitely one of the most targeted malware platforms these days. But no worries, users of Avast! Free Mobile Security are safe. Read more…

Question of the week:  I just got a new Galaxy Note tablet for Christmas. I want to make sure it’s safe and secure before I use it for browsing the internet. Does avast! have protection for tablets?

Congratulations on your wonderful gift, and Merry Christmas! You are wise to think about security for your tablet, because cybercrooks are producing malware for these devices in increasing numbers.

You get Anti-theft protection, remote control and remote memory wipe, plus privacy reports, anti-spyware, network management, Web protection and a firewall. avast!

Is Google Protecting Me After All?

The latest version of Android 4.2, code-named “Jelly Bean” has been released some time ago. While being just an incremental update to the major 4.0 release “Ice Cream Sandwich”, Google introduced some major new features within that update. While offering multi-user support and improved notifications, a new feature which is being promoted heavily, is the built-in app scanner which should protect Android devices from being infected by malware.

The client side app scanner of Android 4.2 is the next step in Google’s attempts to protect their Android ecosystem from malware threats, after introducing Bouncer, a server-side malware scanner used by Google to analyze apps that are being uploaded to Google Play Store. Bouncer was announced in February 2012 and is Google’s approach to prevent malware from being uploaded to the Google Play store as a first line of defense.

Now, some authors claim that third party mobile security tools are most likely not needed anymore, because Google now already pre-checks all mobile apps. I’ve been closely monitoring all those changes and improvements because I wanted to make my own mind on how successful these attempts by Google would be and to find out how our Android antivirus scanner delivered within our free avast! Mobile Security suite (http://www.avast.com/free-mobile-security) would stack up to what the operating system vendor itself would be able to provide.

Since months before the release of avast! Mobile Security in December 2011, our virus lab was working on setting up the initial state of our Android malware database. The database contains signatures of all the malicious files our virus lab guys find over time and is being extended day-by-day to contain definitions of the newest threats in real-time. Currently, tens of millions of Android devices owned by our users download those definitions every day to their avast! client side scanners. So I just went to our virus lab and asked the guys there to provide me with some statistics on the growth of our Android malware database.

As I already stated, Bouncer was thought to be the first line of defense, and tries to protect the main source of app downloads from malicious offerings. Could it be that as a result of introducing Bouncer, our malware database stopped growing or started to decline in size when Bouncer was introduced? Has Google been successful? See for yourself:

Obviously, since February 2012, our Android malware growth has not started to decline; it has not even stalled its growth, but has been continuously growing since that point in time. Read more…
