My phone keeps installing apps by it self, what to do?

i had the same problem earlier and found the solution finally. this issue is there in most of the cheep chinese phones and tablets. these phones have pre installed trojan program which cannot be removed from the phone. i tried many applications including trojan remover and so on. No use... but finally i downloaded No root firewall application from google play store(https://play.google.com/store/apps/detai...). this application blocks all the events and unwanted programs including download manager which downloads unwanted programs without your concern. now i dont have issue. i allow the download manager whenever i want and other time i block download manager and other trojan suspected programs. this solution might help you.

I had the same problem of random apps getting installed without my permission on my samsung s7. Tried factory reset, changing google password, mcafee and malawarebytes. None helped. Then i installed noroot firewall app as Mr. Kesavan suggested here - and mercilessly denied all android and samsung apps. Only chrome, clock, outlook, google maps, wordament and a few more safe apps are allowed thru firewall. This solution is working.

Every little app seems to be trying to do connections unnecessarily.

Thank you Kesavan!

Hmm. I'm wondering if you have an apple phone. Is it redownloading apps you've already purchased. Even free apps?

By the way, the reason why some viruses are cannot be uninstalled is because they have placed themselves in the system directory and for you to remove them you either need to remove them with an application which has root access or another way. I have my phone rooted as it was the only way to remove some issues I had back in March/April.

I have a similar problem, using any malware software does not detect any problem, I uninstall the 3 applications on my phone 'go security, ace cleaner and superb cleaner' these three application no matter what I do keep re-installing after rebooting my phone.

I have uninstalled them successfully . I had this issue either after uninstalling Go Security or 360 security. I cannot remove them, I have tried removing the directories but something is hidden on my phone and I cannot find the source for it which keeps installing them, my mobile boots up saying optimising app 1 of 3.... then after the three it loads up with the 3 that i removed back on the phone.

It is something that advertisers have probably secretly put on the applications which the software developers cannot trace so the applications end up being placed deep into the phone. But I am not sure of the source

I had the same problem apps install themselves on android I found out it was The update of googleplay installing them So when I reinstall OS I dont update GP I get the warning apps wont run but I just back out of the warning an they still run (no installs since)

If on android and your getting the system_protect.apk downloading go to settings> apps and scroll all the way down, there an app with now name about 29Mb , this is the malware, malware bytes doesn't see a file without a name so it skips over it !
