avast! Free Mobile Security – The best anti-theft solution on the market


Application Manager

This one is more of a cool extra feature than it is helpful. It pretty much serves the same purpose as the “Manage Applications” under your Settings. It allows the user to see all the applications installed in the device, force close them and read their system resources (size, CPU usage, etc), as well as Privacy Info (permissions and what they mean).

It is possible to order the app list by name, size, memory, CPU and running apps. There’s also a “System Info” button, which pretty much directs you to your system settings (Manage Applications).

Web Shield

This is much like Lookout’s web phishing protection, which is included with their paid premium services. It basically searches every site you access for potential threats beforehand.

The internet is a very wild place, and even if you know your cellphone’s apps and files are secure, the web may not be. There are websites that attempt to get private information for fraudulent activities. With phishing protection accessing, surfing the web and clicking random links will be much safer.

After using this for weeks, I have not noticed any lag in the browser. Other services that offer this feature show a slight delay every time you access a website. It may not bother many, but it is nice to see that avast! has made the process rather smooth.

SMS & Call Filter

This is one of the most helpful features that the avast! app offers. The user can block incoming text messages and calls, as well as outgoing calls to/from specific phone numbers. For some reason it cannot block outgoing texts, though. Regardless, this is a very helpful feature.

The filter can be set by groups, and you can choose what time and days you want the phone number(s) to be blocked. It is also possible to toggle on/off outgoing calls and incoming texts and calls separately. If you happen to miss any important calls/texts, there’s also a log that informs you of all the times a call or text was blocked.

This turns out to be very convenient. Not only is it good for avoiding stalkers, or to prevent your parents or wife/husband from calling you during working/school hours, but it also works as a parental control tool. Yes, you can stop your kids from calling you (or anyone else) during school hours. Simply block the numbers you don’t want your kids sending or receiving texts and calls from, and you’re set.

The avast! app can be password protected, so it wouldn’t be possible for anyone else to change the settings. Unless, of course, the user uninstalls the avast! app. This loophole can be fixed if avast! were to include password protection for other apps (or if you use the firewall, which we will talk about in a bit). It would be a great addition in the future, but avast! currently focuses on security more than parental controls.

I have tested this feature and use it frequently. It works like a charm, and it has never failed me.

Firewall (Root Feature)

Everything mentioned above is great, but root features are what really makes avast! stand out from the crowd. The Firewall is only available for rooted devices, but it can be of great use if you have rooted your device.

The Firewall’s purpose is to let you block apps (of your choice) from being launched. It allows you to choose whether you want them to be blocked while in WiFi reach, 3G or roaming.

There are countless reason why you might want to use this feature. The most notable include saving battery life and data consumption. Certain apps are battery/data hogs, and you may not want them running all the time. This Firewall allows you to stop these apps from running, whether it be through direct interaction or in the background.

This also helps as a parental control tool. It is definitely a good idea to stop your kids from accessing certain apps.

It would be amazing to see this feature work in non-rooted devices. This may be much more complicated to achieve, though. Wouldn’t it be nice to block all that bloatware? In my experience it worked very well, and I highly recommend it for root users.

    Mine keeps saying the definitions are out of date, but won’t let me update! Gerrrr

    • aranea

      I have the same problem. If I go through the app itself and check for updates then it says it’s up to date.

    • vid500

      Yes mine to, i had to restart the device to update. But now it looks like it works just fine.

      • aranea

        Hmm I haven’t tried restarting. I’ll try it next time. Do you guys have the password protection to open the app too? And I run this on my Atrix. I’m trying to find some common ground that may help them solve the problem.

  • staryoshi

    I dabbled with the app and it was solid – I’ve had great experiences with Avast! on the PC in the past, too. I will consider using it again if I root my phone.

    This article reads more like a paid advertisement than an overview, though… (Even though it’s for a free product) – Just my two cents.

  • Donald Williams

    Downloaded and giving it a try. I am sure I dont need it but ya never know when it may come in handy especially since i have some shady workers.

  • spazby

    I have lookout and am very happy with it…

  • http://youtube.com/user/jawckamoe Marcus

    I downloaded this app when you guys mentioned it a couple of weeks ago. I used Lookout before and when I downloaded avast!, I fell in love. It was really the root features that made me stay with avast!. I highly recommend this app. The anti-theft settings are great, and everything about it is nice and smooth.

  • David Hughes

    Great app, I like the enhancments when rooted too, Galaxy Nexus

  • http://www.facebook.com/home.php?#!/profile.php?id=583695634&ref=profile Rahul Singh

    I have been using this app for about 2-3 weeks and it’s the best mobile security.. and if your phone is rooted you can access the firewall feature.. great app!

  • Ivan Samuelson

    What about recovery mode and preventing flashing a rom or doing an sbf? That would wipe out the app.

    • Probiewankenobi

      One of the features that you get if your phone is rooted, is the ability to install the app deep into the phone so that it won’t get erased from a hard-reset.

  • McLovin

    I also downloaded this a few weeks ago and was very impressed. I’ve had Lookout Mobile Security installed since the beginning. I got a bit concerned a while back with the reports that all these apps were not very good at detection.


    So I went crazy and downloaded several. But then the Google guys came out and said it was all scare tactics.


    I noticed my phone becoming very sluggish and have since uninstalled most all of them. My phone runs much faster now. LOL

  • cristian cristiandonose

    Coming from Bitdefender and im very happy i did because this free and much better app.

  • Lightning7

    Features (especially stealth mode) are all very essential just for added protection. Prevention is better than cure.

  • romy134

    Got it, works good. Now just need to get root..

  • http://alxrock.deviantart.com alxrock

    I used to have Lookout, and stuck with it for about a year and a half (One year with Lookout Premium thanks to winning a free 1-year subscription). I just switched to Avast a few weeks ago and have been really impressed with all the features.
    I’m not worried about viruses and just keep an eye out for sketchy apps and permissions, but I like the lock, wipe, and tracking abilities. Plus if I decide to root again, there are even more great features I can tap into.

    • R.S

      Like mentioned last time Avast was written about here on Android and Me, I too had a subscription to Lookout premium. It worked great but since I never lost my phone, I didn’t really use the premium features.

      Obviously you can’t put a price on peace of mind but if Avast offers the same, if not more than Lookout, for free, why would I or anyone else pay for the premium services of Lookout that we might never need.

      • http://alxrock.deviantart.com alxrock

        Exactly. I didn’t want to pay annually for a subscription, so I almost bought Cerberus. Luckily I started seeing a lot of good reviews for Avast and realized they offered everything I wanted and more for free.

  • Ps3y3Ops

    I find that in most cases it is better to have it and not need it than to need it and not have it. Like insurance, for instance.

  • T1beriu

    This clearly is a paid for review.

    • raptor

      A&m should disclose when this is paid ad.

    • Jennifer

      How does it look like a paid review? It looks like all their reviews, talks about the features and what he thinks of them. Just because it is a good review does not mean its paid. I am using the app and it works exactly like they said with the only thing I noticed is that it keeps telling me the defintions are out of date even though it says its up to date. Other then that no problems.

  • 666

    3 page article of a app? Hmmm… I wonder how much Androidandme got paid to post this up.

  • T1beriu

    Another example of Avast paying another website to advertise their products: http://android.modaco.com/page/news/_/android/avast-mobile-security-brings-fanastic-fre-r161

  • sylar

    Yea I like this app, I downloaded it when it was still in beta and was impressed with it then and even more now that is it out of beta. It seems to work well and has never reported me having a virus but then its hard to really know isn’t it. Still it has plenty of nice functions.

  • ArticulateFool

    One of the best apps out there!

    I would like to see some NFC security measures put into place.

  • _Diego

    I had lookout but uninstalled it since I used the free version up to now. I am very pleased to see them go moblie. As you already mentioned, they have a lot of features, serious anti-theft protection and all of that for free. Combination of success!

  • Prime

    Love avast! I’ve been using it for years on my pc, and never ran into any problems!

  • Scott

    I tried this app and I loved the breadth of features, but it unfortunately isn’t as intuitive as Lookout. I really like Lookout’s web interface for locating/wiping the device so I think I’ll stick with that. As far as the premium features, I haven’t signed up for them and probably won’t unless I actually lose-lose my phone and need to lock/wipe it. No sense in me paying for those features “in case” I lose my phone when you can simply sign up for them on a whim if needed. I’d like to use Avast as that’s what I use on my computers at home, but it offered more than I feel I need.

  • raptor

    Every novice hack will say u thank you for rooting when u will catch his virus or keylogger via app, email or website

    • TheCraiggers

      Are you a shill for Motorola, or just not very smart in general? You have to give permission to an app for it to use root.

  • Rodd Clarkson

    Windows wasn’t the most targeted because it was the most popular, it was targeted because it was the most insecure. For example when Linux and Apache had 70% of the Web server market compared to windows and IIS, it was the Windows product that was attacked because it was vastly more insecure. Keep in mind that both Linux and Apache are open source so source code availability has little to do with security.

    • TheCraiggers

      Are you seriously comparing the desktop PC market to the server market?

  • JustaCriticalThinker

    I know Android and Me writers can clearly understand the difference between “lose” and “loose” and their respective conjugations. Therefore, this must not have been written by this site and is instead clearly a paid advertisement.

    Either way, shame trying to pass this off as an article OR shame on your grasp of writing.

    • gpmillerjax

      This same article is on 32 other websites so it is safe to say that Androidandme did not write it.

      • gpmillerjax

        Also you don’t need this app on your Android device….listen to Google, they know what they are talking about.

  • lokidokie

    I really don’t see the point of virus protection on android.
    I’ve never used any and never had a problem.
    Though I do use avast for my PC.

    • Gordon

      i use Lookout. i like it for the -

      1. “Find My Phone” feature.
      2. App Scan for Spyware. i purposely installed “SMS Replicator” on my EVO and then scanned it with Lookout. Lookout detected it. i like that.

  • Chad

    This is the best mobile security app available for your phone if you don’t get this your undermining your security, I got this the day it hit the app market, especially since it’s free with all the features it packs. I went to T-Mo to get my sim card updated on saturday i changed the sim and turn my phone back on, I was with my girlfriend as soon as I turned the phone back on with the new sim it sent my girlfriend a GPS map of where my phone was, the IMEI number and the telephone number of the sim that was just placed inside. I was just going through a routine sim card upgrade but if my phone was stolen this would have been great protection. It also asked me for my pin once i restarted if it’s stolen and the thief doesn’t know the pin, it’ll lock your phone and you can control your phone remotely from the numbers you have listed on file, for me it’s my gf and brother. great security. get this app because it’s the best security app available in the market, it’s better than Lookout, especially if you have a high end, expensive phone or have valuable data on your phone.

  • Tom

    I have a great app. What does Android & Me charges for a “review” for page?

  • http://www.openintro.com OpenIntro

    What’s the battery life footprint like when using a mobile security application like this? Is it not always running?

  • Gordon

    i’ve read that Lookout uses about the same energy of an average email sent/received over data a day.

  • Voliam

    While the need for this may be minimal for those that aren’t rooted, don’t sideload apps, and practice safe surfing, an ounce of prevention is worth a pound of cure, as they say.
    A recent article warned of the increase, in 2012, of hackers concentrating more on attacking mobile OSs, due to the rapid proliferation of mobile technology. That presents a whole new world of possibilities and challenges to hackers.
    After all, isn’t that what they live for?

  • Khayman

    I’ve used Avast, think its a great app, but really is a battery hog on my HTC Sensation. Getting half the battery life I did before. Have gone back to Lookout until it gets sorted!!

  • vid500

    I’m using it sience it came out and I’m very satisfied. I do not see a dramatic decrease of the battery power. But I still doubt the need of antivirus protection for android devices. But it can’t hurt.

  • Ngosia

    Good article,
    I am a blogger in Kenya and my phone McFee which I have been hesitant to activate since I do not have a second line for notification.
    I will give this a try coz I hate having more than one phone. I am also looking to have guest writers on my blog tech101kenya.blogspot.com. Anyone willing to be heard in this part of the world?

  • FormerYooper

    So … I have bought my first tablet (Lenovo Ideapad K1) and have installed Avast Mobile Security on it. Now, please don’t think I’m dumb … but here is my question. To have the Avast protection working, I have to have the Avast Mobile Security app running right? I know it’s a dumb question, but like I said, this is my first tablet & first experience with Android …. so I just don’t know.

    Just having Avast installed on my windows system, it’s running all the time. I just need to know how I know it is protecting my Android tablet.

    Thank you in advance for your help.

    Has anyone used Avast Locate function? It works perfectly for every time I test it but I find out within a week my husband has been an unknown but the same house a few times. He denies he has been away from home and even has her mother(I don’t trust her) as witness. However, I can’t tell the truth that I have installed the Avast apps in his phone. Will the function really screw up sometime? Every time when he appears in the house Avast is not using GPS, once it was on WIFI(accuracy 39m), twice on network(75m). The house is at least 10 km away. What should I trust?
