Hello!
This thread is for problems on an Android tablet.
I have had free AVG products on several PC:s over many years, and these products have worked fine, so I installed the free mobile version of AVG on my tablet and on my smartphone, and have now got big problems on my tablet.

Can you please tip which programs there is that get rid of virus and malware on mobile android devices that already are infected, and how to install these tools on an already infected device.
The problem can be to install anti virus tools after the device already has been infected.

I have an Asus TF300 with WiFi (no 3g) tablet with Android 4.0.3 that has some kind of virus or malware which has overtaken the device. The evil program tries to log on to my device when I start the device. I can see that I tries to get thru my logon start page where I normally type my password, and it takes control of the device, goes thru all menus and programs, tries to start wifi if I have stopped it, tries to exchange networks to one that is near, starts games and other programs, and so on…..

My device has worked fine for months. I installed AVG Free Antivirus directly when I bought the device, have updated it, but after months of good functionality the device finally got infected anyway…..
Because the evil program, what ever it is, is so quick an evil, I can't control the device at all, the program has taken over, so I can´t do anything with my device.

I have a lot of free games installed from Google Play, and the problems occurred after installing the latest two games, two days ago:
Where’s My Perry? Freehttps://play.google.com/store/apps/details?id=com.disney.WMPLite&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5kaXNuZXkuV01QTGl0ZSJd

Maybe the problems came with the above, but it could have come from earlier installations, or from other internet sites….

Some sites on the Internet tell us to uninstall the latest programs you installed, to try to locate and get rid of evil programs, malware and virus. The problem is how to do that when the device is so badly infected that you cant do anything with it but looking at how it is taken over by an evil program…..

There must be some program/s that I could boot the device from, or which could be run from Internet, and which detect the evil program/s and destroys it/them, without destroying other good installations on the device.

The problem is to know which programs or functions there is to use, how to use them when the device already is infected so bad that the device is overtaken of an evil program, so you can’t do anything your self.

Hmmmm, what is there to do to get the device to work again?

You print a lot of good tips, but can you please tip which programs there is that get rid of virus and malware on mobile android devices that already are infected, and how to install these tools on an already infected device. The problem can be to install anti virus tools after the device already has been infected.

My tablet is not rooted, and I have no advanced task killer installed.

More info:
Mobile Phone
I normally use my mobile phone, Ericson Neo with Android 4.0.3, as a mobile wifi hotspot to reach Internet. The mobile phone is not rooted, has the free version of Avast installed since yesterday, and earlier I had the free version of AVG, but I changed because the problems with my tablet. Since I bought my tablet, I normally don't use my mobile phone any more for downloading and playing games directly to/on the mobile phone, even though I've still have 20 odd games still on the mobile phone. I have a 8Gb SD-card installed in the mobile phone, and I normally move everything to the SD-card using Android Assistant, leaving the built in memory in the mobile phone almost clean.
I use Android Assistant continuously to clean cash and system memory.
I continuously update the mobile phone, OS and applications.

Tablet
The tablet has 32Gb built in memory, and I normally don´t have SD-card installed in the tablet. I use Android Assistant continuously to clean cash and system memory.
I continuously update the tablet, OS and applications, and Asus had not the latest Android-version 4.0., fore distribution to my device a couple days ago when my tablet still worked fine. I therefore still use Android 4.0.3.

My own test
The AVG mobile antivirus program for Android, don't work for me in this case, because of that my Android-device got infected, so I tried Avast! but that didn't work either.
Last night, I successfully installed the free Avast! Mobile Security onto the device, as a test to get rid of the problem. It was a struggle and war against the evil program, that has taken control of my device.
My way to install Avast was to use my desktop computer with fully updated Win 7 Ultimate, updated free versions of ZoneAlarm and AVG, logging on to Google Play with the account I use only with my tablet, and downloading Avast, which Google Play than automatically forced down to my tablet, which normally use the account.
The download to my tablet worked. Avast installed itself onto the device, and after a long struggle against the evil program I want to get rid of, I could secure a password to the Avast-program, so the evil program couldn't change or uninstall it.
However the Avast did not locate any problems using the scanner, so the evil program is still on my tablet, and still causing damage and frustration.

I still don't know what the evil program is, what it is called, and how to get rid of it. I still haven’t found a look alike problem on the Internet????!!!
I can buy full versions of all tools for malware and antivirus, but I have no guarantee that any of the programs will work, so I won’t do that.

I will now try to install other anti virus and anti malware tools the same way, to see if any other program will kill the evil program. Every tool I try, will take me some hours to try, because that the evil program on my tablet has nearly total control of the device, giving me very little room to work…….

AVG and Avast don't work in this case. Do You have any tips?

Please continue to tip me whenever you have got more info about how I can get rid of the evil program.

Hi Baltazaar,

I have an Asus TF300 with WiFi (no 3g) tablet with Android 4.0.3 that has some kind of virus or malware which has overtaken the device. The evil program tries to log on to my device when I start the device. I can see that I tries to get thru my logon start page where I normaly type my password, and it takes control of the device, goes thru all menus and programs, tries to start wifi if I have stopped it, tries to exchange networks to one that is near, starts games and other programs, and so on…..

We are not aware of any similar Android virus. It seems like there are random inputs provided in the system (maybe the touch layer is damaged).

There must be some program/s that I could boot the device from, or which could be run from Internet, and which detect the evil program/s and destroys it/them, without destroying other good installations on the device.

We know no such custom ROM. Moreover, such ROM could not be used most likely, because the bootloader will be probably still locked as your tablet is not rooted.

My tablet is not rooted...

It is unlikely for the tablet to be infected in such extent when it is not rooted - the infection would have almost no rights. Try remembering if you have allowed some strange actions for particular apps.

I recommend either going through all recently installed apps and uninstalling the suspicious ones or perform hard reset of the device (remember to back up your data first).

Maybe other Android users will share their experience with a similar infection in this thread...

Hello TechBuddy,
Thank you for your answer, maybe you are right about problem with the touch layer. I have had that thought before, but sorted it out of my mind earlier, because I thought that I could see that the evil program (if there is any) used different characters and numbers trying to login (after I had struggled against the evil program to alter so characters can be seen). The evil program also checked and unchecked many checkboxes, trying it’s way threw the system and every program and functions. It could still be random, but I think it’s an evil one! The evil program even activates and deactivates wifi networks the tablet can reach. However, before I will go back to my store, and try to make them understand that this can be the hardware problem, as you suggest, and maybe get it fixed on the guarantee, I have contacted Asus support by e-mail, and is waiting for a response. Maybe they agree with your diagnose, and want me to visit my store with the faulty or damaged tablet, we will see. In my thoughts, this still is an evil program, and I don’t think I will be alone with this problem – It will be a pandemic problem, if it’s an evil program. I hope you are right, and that I am wrong.
Have my thread open, and please be alert on likewise problems.
I’ll be back soon, after contact with Asus.

Hello again.
I have just been in contact with Asus and done a factory reset, but the persistent, evil, annoying and frustrating problem is still active, taking over the device. I can’t even begin to configure and install the tablet, choosing country and keyboard, before the evil problem takes over again…..!!??

The factory reset didn’t work, so I will now go back to the store, to get my tablet fixed or exchanged on the guarantee, regardless of malware, virus or hardware related problem, because no one seams to really know what this really is....??!!

…..evil thing….but thanks…

Hi Baltazaar,

If the factory reset didn't help, I think it is really a hardware problem. As mentioned before, we met no such Android malware in past.

Thanks for coming in the AVG Forums. After ASUS acknowledges it is a hardware problem, please let us know what component was actually faulty. The issue is really strange and the information may help someone in future.
