It's a good anti virus app. I noticed that with the recent updates, the password keypad kept changing in sizes and design. The most recent update has the number much smaller than the last one. It is a big black screen with very small numbers. Why can't you have bigger numbers instead of empty black space?? After 3 updates still no improvement on the keyboard size!?!?!?

I have just upgraded phones and logged into my account. My current subscription is valid till October 2018. How do I activate my licence on my new phone? I would expect it to pick it up and not ask me to upgrade. It is not picking up my device. Can you please help? This is annoying and not useful

R70%
by R####:

Paid version displayed as free version since last update. When logged into Avast account it is showing licence valid till 2046. Correct this ASAP on 1st priority basis. Why you need a day or two to fix a bug. Its been more than a week now problem still exists. If takes so long to solve a bug how could I rely upon Avast providing realtime security?

After update it to ver.6.1.3, Avast anti-theft feature is combined in this app. Here after doing all successful configuration. And after set pin for theft setting. It's stucked after some 2-3 days. I uninstalled it , then configured all settings again. But still same issue occurred..!! I am getting blank black screen when I go to anti-theft section.

H70%
by H####:

I really lile Avast. Not too much junk. AVG has lost their minds with recommended apps that seem misrepresented, like your phone is infected, down load phone cleaner. It is just what "may" happen but it looks like you should do it right away. Avast is a great app with none of the misleading ad-ons.

U70%
by U####:

Do NOT LIKE how the Clear Clipboard button was eliminated in the new update. In addition, in the new update I know I have items in the Clipboard and I've only been notified 1 time that the Clipboard needed to be cleaned. DON'T ELIMINATE GOOD FEATURES IN FUTURE UPDATES!

N70%
by N####:

Well guilt finally won as I've been using Avast for years for free but at $5.49 for the year they deserve it. It has caught plenty and saved my ass. As soon as I downloaded it found it a couple things, 3 other similar apps missed it, that I was testing.Plus the goodies that like to attach to your clipboard with music. Impressed works very well.Also have "Lookout " that came with T-Mobile so it's the perfect balance..Hats off! True peace of mind.Thanks for letting me freeload,great job!

For at least the last 3 weeks the call blocker feature isn't working at all and I've contacted customer care 3 times. It would be great to get some help with this since I've paid for the pro version. Otherwise I'll have to find another app and cancel my subscription.

I can't uninstall Avast Anti theft app! Tells me it is not supported and suggests I uninstall it, but the uninstall option is greyed out in settings. Great, now I have this piece of junk just eating up space. And yes, I did attempt to remove the program as a device administrator and Settings crashes. I tried "deactivating" from the Play store as well, and despite the button saying "Deactivate" (i.e. and not "Uninstall"), it just pops up a box saying it has to be removed as a device administrator first...which just brings me right back to it causing the Settings to crash.

My phone randomly starts beeping at max volume very shrilly. Cannot find a source. Have tried killing one app at a time. Kill all seems to be only thing that works. Could that be a result of this app and its security features?

J70%
by J####:

Seems to be okay, but I think they should be more selective in advertisers. Having run a scan - clean - it's disconcerting to see an ad that says "you're infected!" immediately below. Also, have ads from an unidentified source that are not getting caught, but nothing else finds the source either.

Z70%
by Z####:

It's a very good security app and all. However, ever since installing it, I've been having problems with Avast running in the background, Spotify playing and using Facebook all at the same time. Before installing Avast, Spotify would never turn off without me turning it off. I'm not sure if this is because I've installed Avast or it's a problem in the new Spotify update.

Avast mobile security is a great little app that does everything you really to do ,to keep your phone and tablet secure. I've used this app for many years and never had a problem. The only issue I ever had is the ads that keep asking to go pro. Otherwise, it's a great little security program and I just love it.

I did create a webapp converted to apk , and that stupid avast showing me the app contains virus.

U70%
by U####:

(Avast has left the competition stranded in its wake! A great way to protect your privacy!) That was my review before the developer took my money and Ads returned, support is non existent. Bulls*it service. Stay AWAY.

U70%
by U####:

Constant notifications are annoying, but it appears to do the job. The latest update demanded lots of new permissions like my mic and calendar... for "minor bug fixes and stability improvements"?

W70%
by W####:

I'm using the paid version, use it on everything I own. It's not as good as the PC version but at least it better than McAfee! You do need to clean cache and run virus scans to keep your phone running great! Learn how to use this App and be safer on the Internet!

U70%
by U####:

I generally love all things Avast, but the direction of this mobile app is horrendous! The entire app is basically an obnoxious advertisement for other Avast products or for for a subscription service to eliminate ads. This app could be more streamlined if it just did what it was supposed to do.

Chrome browser support wont work on SS galaxy S6 Android 7. Turned on Chrome support in Accessibility already but when return Avast screen, it still dont enable. It keep posting notification on thia issue. Please fix it.

U70%
by U####:

Works fine for me it the chrome support button won't turn on and I keep getting notification that there is one issue when I scan. I've gone to my accessibility settings and enabled chrome web support but it won't recognise that. It's annoying. I have an s7 btw. Never had this issue before. I've also given every permission and admin. Privilege.

B70%
by B####:

This is an excellent app. While I have purchased the Pro (just don't like the ads), the free version is truly amazing, and I highly recommend it. Avast is a "can't go wrong" app -- try it for yourself!!

U70%
by U####:

I understand that the free version contains ads. But I expect to see the ads when the app is open and not running in the background. My charging screen is NOT part of the app and it should not be affected by it. Please revert to a less intrusive ad system or illuminate me on how to deactivate such "features" or I will be moving on to some competitor's product.

U70%
by U####:

Last update replaced Pro version with basic free version. I have a current subscription and cannot download Pro as there is a connection error every time, regardless of various Wi-Fi or 4G, and I am running Android 5 so not the OS fault. Nothing else has a connection problem, only Avast. Help ticket raised 9 days ago, no human response, only automatic reply. Not impressed.

A70%
by A####:

Was servicable enough but now registers multipe errors per day and insists that I uninstal it as the app detects itself as the single most notable problem with my phone. I listened to it so I've just uninstalled and cancelled the subscription!

J70%
by J####:

Lost my pro version with latest update. Their website still shows my devices properly but the app does not! My phone seems to be working but my tablet is still broken. Both are Samsung products.

U70%
by U####:

Paid for app. Worked for 6 months. Paid app has quite working now. Back to ads and non paid features. Avast has yet to respond to my emails sent 7 days ago. Very upset user. When it works, it works well. I WANT MY PAID APP BACK AVAST!!!

Thank you so much i had a virus where innapropriat adds popped up on every day use of my phone so i decided to try ur app (as recommended by freinds and family) your app found the threats and sorted them thank you so much you dont know how much i apprecuate this anyone looking for a good antivirus app stop because YOU are looking at it!!!!

by U####:

I like the SMS feature that allows you to text commands to your phone in the unfortunate situations where you either have lost or had your phone stolen.

U70%
by U####:

Avast is pushing the boundaries between functional and a platform for ads. The app scans, says tap to see what was found. I do that and come to the conclusion that the avast just scanned up a bunch of ads for me..

U70%
by U####:

Almost every time I click a button in the app an add will pop up immediately after me doing so and take me to that adds website like i clicked on it. this is absolutely unacceptabale!

Doing great apart from the fact its not able to scan my wifi. Constantly fails on every try. Have uninstalled/reinstalled... No difference. Other than that its good.

Thanks for listening to your loyal & longtime customers. You have regained my trust by making major improvements to the new UI. I have installed again on all my devices as a paid suscriber & can gladly say that I'm a very satisfied customer again!!!

Now locked apps request pin everytime I get out of them, while in the previous update you could choose if make locked apps to request the pin only after switching off the screen. Editor: after 2 updates problem not solved yet

E70%
by E####:

But got a virus and it didn't see it or find it would be good if it scaned your internet files too that's where the virus hide. Since last update it done do the Wi-Fi security check just fail..

U70%
by U####:

Great functions - minor quirks & 1 minor but annoying bug (clock on boost screen does not update) plus latest version shrunk text in boost screen so it is very difficult to read

U70%
by U####:

It was great, now with the current update all you see is pop ups. I want to see my virus scanner not 2-3 pop ups before i can get to the scan button

R70%
by R####:

I installed and after my battery go down for half day. Before my battery worked all day long. I not really recommend this app. May be good but for the battery defenetly not.

S70%
by S####:

After latest update my App Locking feature has ads, even though I have a Premium/Pro license. When I try to fix it I get an error message to check my Internet connection and try again, even after I've tried to uninstall and reinstall a couple of times. Very frustrated. If I can't get rid of the ads I'll change mobile security providers Thanks for the note Tereza. However, even after the latest update I still cannot the app lock on all the apps I was previously using it on. Still not happy

G70%
by G####:

Theres an advertisement titled, "warning your phone is infected." The typical message trying to trick someone into clicking it and recieving a virus. Why is that an advertisement on an antivirus.

U70%
by U####:
