I use official roms.
I tried all kind of messy and useless apps a few days ago when I planned a factory reset under privacy.I doubt those apps' safety.
I afraid that a virus or malware affected the system, can a factory reset completely clear all of them including internal SD(no external)?
I'm wondering if they could enter the system restore partition. I updated to GB after the factory reset.
Thanks
Y use official roms?

If I have virus or malware in my infuse ,can a factory reset compeletely clear all of them including internal SD(I do not use external)?
I heard it might not be. source: http://forum.xda-developers.com/showthread.php?t=1197167
Now I updated my infuse to gingerbread, which means that OS is updated. Coming back to my normal life, I installed those Apps that I'm sure there would not be virus or malware. I think the whole ROM was replaced during the update.
I accidentally turned on Google Back up service, is it possible bring "those stuff" back?
Thanks

Do you have a virus or malware running on your phone or are you just asking in case something happens? I'm lost, your paragraph above is confusing as hell.

Lookout. It look out for me? Maybe? lol.
OP is saying that a few days ago, he or she installed some untrustworthy apps. Subsequently, OP did a factory reset and installed GB. Then OP put only trusted apps on the phone. The question now is whether the untrustworthy apps from a few days ago could have some residual effects that still pose a threat (via Google Backup or otherwise), despite the subsequent factory reset and GB installation.

Thank you sir.. Umm.. I doubt it. I think that should be sufficient. Reactor, do you mind sharing the app with malicious intent?
ill just say with computers almost anything is possible. a virus surviving the update as well as a factory reset through settings>privacy is not likely though. that would only be plausible if you had root and the virus made backups on the system partition and data partition or sdcard one to survive the update and one to survive a reset. but if you want secure you could reset through settings>privacy then Odin the update again without reboot selected, then power down and boot into recovery and wipe data from there then install apps. also don't root the phone and don't install apps from pdanet or other illegitimate sources of apps.
but when it comes down to it malware on phones is kinda rare and most of it wont be able to get root permissions on the new update. just download apps with a degree of discretion and stay away from alternative sources for apps.
If you didn't have any malware or viruses before you started installing apps, then it may just be an app that may be spamming out junk and crap into your notification bar and etc. Best thing you can do is track and delete the app causing you problems. I was using an app called Speed Booster Lite, I found out it was spamming ads in my notification bar, I deleted the app and the crap was gone for good. If you Factory Reset your entire phone, Your virus or malware is likely to be gone for good since you erase all files and cache from the internal hard drive on the phone. Your phone is like your computer, If you reinstall windows after you have had viruses, there completely gone!
Edit: As far as Prevention against malware and viruses, I find a lot of these apps to be complete BS and a lot of them do absolutely nothing for you but hog up resources on your phone.

Well, not quite, but saved me a lot of aggravation! I know most people know this, but I thought I'd share. I had serious issues with a certain app from the market. After a few attempts and a reboot all my apps and system services were FC'ing. I rebooted several times, and the same happened. I could do nothing.
I researched, and others said you need a factory reset, so I girded my loins and did the deed.
By great fortune I had only recently cleared a couple of GB on my external SD and backed up the entire system with Titanium Backup. I could then easily not only restore the apps, but all the data, relieving me from the need to reconfigure several dozen critical apps. I even had my bluetooth and wireless settings restored.
Cannot praise it enough, just coughed up for the pro version to back up using dropbox too. That way, if my Note should ever get purloined, I can buy another one and restore at will.

Completely agree! Ever since I converted from Symbian to Android, I could not resist myself with the amount of "playing around" that is possible, and hence the need to wipe all your data.
Over the weekend I used the TB at least 5-6 times and every time it worked flawlessly.
Other uses include- Market application which is a sore point for many custom ROMS, I could solve the issue by just toggling it to user app, uninstalling, installing the newer version and making it a sys app again. As simple as that!

TB was the first ever app i paid for. Pro version was not even avaible through android market for my country by that time so i had to donate to his paypal account. It is one of the essential apps on android and it is the biggest reason i root my phone even tho i prefer to use stock roms.
I am trying and getting absolutely nowhere disabling the OTA update nag screen. Even though my phone is rooted I can not disable the OTA update service nor rename the otacerts.zip file (as it still says access is denied.)
Motorola is refusing to help me aswell.
Surely there is a way of doing this?
Any help would be much appriciated.
I disabled the OTA and a whole bunch of other services using Greenify. There is a thread in this forum, with a comprehensive list of services that can be disabled (far more than I disabled). I also disabled some apps from multi tasking. I typically get 3 days of moderate usage. So its a win win situation.
Can u tell me the apps that i can disable to save battery life.

I understand to do this I have to install the xposed framework? Something that does worry me after seeing the dreaded boot loop recently.
I am under the impression from some thread in here, renaming otacerts.zip in the system folder to otacerts.bak can disable the function, but likewise I am a bit worried about bricking my phone. Motorola have informed me that updates are mandatory now and they will not tell me how to disable OTA updates.
The lack of working apps for things like this is also putting me off playing around too.

I got rid of the nag screen by disabling an app called "motorolaOTA" and erasing the cache in recovery to delete the OTA file. I really wouldn't recommend upgrading to 4.4.4 as I eventually did anyway about a week after disabling the nag screen (wanted to test it out lol) and in the process hard bricked my phone.
So, disable "motorolaOTA" and whatever you do DO NOT upgrade!

Sorry, I dont have access to the phone right now so cannot list the services. But I think I fed some miss-information, I now realize that I used Titanium backup to freeze the unwanted apps. This being all Motorola services. I then used Greenify on my messaging apps, like Facebook, Whatsapp and others.
But I do agree with another comment in this thread that rooting does mess up the upgrade process, it becomes a real pain! So its worth considering to not do it. Like others I have not upgraded to 4.4.4

This helped me with the upgrade (Phone is unlocked, rooted and had xposed modules on it before the upgrade)
For me to succesfully update the OTA i had to do follow the steps in the OP of this Post. I tried a lot of flashing, but in the end only this worked:
http://forum.xda-developers.com/moto-g/general/ota-file-indian-dual-sim-4-4-4-t2810166
Just follow the steps below the text:
REVERT TO STOCK WITHOUT LOSING DATA OR ANYTHING ELSE
After this, you have to root it again with superboot. It's worth the effort to have 4.4.4. The phone feels more responsive for me.
Problem Solved!
I installed "System app remover (ROOT) by Jumobile". Its a free app in the google play store. This allowed me to uninstall Motorola OTA service.
The upgrade nag screen has yet to re-appear, and my phone is otherwise functioning perfectly.
Well done! I had never heard of this app, it looks neat. I use Titanium primarily for backups, the ability to freeze apps is just a nice bonus. I wonder if Titanium and "System app remover" work using the same method? With Titanium its easy to restore a frozen app. I read that "System app remover" puts removed apps in the recycle bin. I'm wondering what the chances are of this storage getting erased by accident, making it harder to restore?

So frustrated there will be no decent normal sized Nexus 6 and the Z3 loses camera features when unlocked ?

There is no "usual" number. Some phones got root before they were even out officially. Some took a few days. Some took over a month. And some end up retired without a safe root option.

Never thought of using adblockers like AdAway, preventing a total waste of mobile data for loading unwanted ads which easily consume ten times the data needed ?
Never thought of kicking out bloatware also wasting your ressources ?
Would love to see root but for now I can manage quite fine without it... There is less bloatware then with certain other brands and you can uninstall or disable quite a bit.
The few things I WOULD like:
* Completely remove unused system apps
* Change LCD Density (it's all soooo big now)
* Full SDCard read/write access for all apps. (I love quickpic as a gallery, but because I save my pics/vids to sdcard it can not remove anything now)
* Titanium backup. Have never ever had issues with this (only user apps+data for me most of the time) and that's with switching between different roms, brands, aosp/stock, etc... Never failed me

ABP (please call it "Adblock Plus" so every readers knows what's meant) does not require root, but it's not too capable running under Android. It does a brilliant job with FireFox and Windows, but the Android implementation only captures a fracture of annoying ads. And: No plugin for defining your own black lists under Android.
AdAway additionally removes annoying ads from a wealth of apps. Just doesn't work without root.
Ok, I can hear you: "If everybody uses that means, app developers won't get paid."
Yes, that's correct.
But:
a) If I really like an app, I'll buy it. Example: Poweramp. NO ads, no annoyance. It just stops working after some time. I regard that as ok. I do NOT like apps getting on my nerves all the time.
My formula is simple: Annoying ads = deinstall, no purchase.
b) A majority of free app developers uses that "evil" ads, appearing at places previously occupied by regular buttons - so you tap on them although you just don't want to.
If that bad behavior gets to a stop, I'll think about disabling AdAway again. Fair play - but on BOTH sides.

Last night i got some pesky malwares. For now i think i removed them. Get Avast and see what it can find. After that try to remove the files from file explorer and the most important thing - go to Settings-Security-Device Administrators. From there remove everything and now from Avast you should be able to remove the infected apps. Hope i helped
Tried cm's stubborn Trojan remover from play store and it did the trick- as in disabled the infected processes but at end took my mail ID with followup request if raised to get the device cleaned from malware. Cross checked from Malwarebytes and kaspersky, and looks seemingly clean with no active culprits. Though not checked with WiFi or data connection through sim.

Did it root your phone first? Else I can't see how it would be able to get to those apps installed as system. If so, if it was me, I'd unroot my phone at the very least & uninstall the CM apps since they do not have a good reputation so far as data snooping goes and excessive app permissions etc goes.
eg (from The Capitol Forum)
The apps require extensive access to the devices on which they run, and they are able to harvest a great deal of data about users’ interests, demographics and location. Cheetah Mobile’s business model is not significantly different from the way in which some major American tech companies such as Facebook monetise their free products. However, Cheetah Mobile is different from American tech companies in that its headquarters are located in China and its data servers are primarily located there as well, and its main business partners are major Chinese tech firms. The Chinese government, according to sources, accesses its companies’ data for internal security, economic competitiveness or other purposes. Cheetah Mobile, and similar companies, represents a major point of entry for China to access American app marketplaces and their users to gather information. However, U.S. government officials in national security and intelligence agencies are highly aware of surveillance and hacking both inside and outside China, presumably coming from actors affiliated with the Chinese state.

Now I haven't used the app you quote but if it didn't root your phone then it can't have removed the malware and they are likely up to their old tricks ie the app doesn't really work, they have just been blocked or something. (Ask yourself why aren't there other apps from well known companies that can remove trojans in system on play store?) ANd with their dodgy reputation for ads, & selling user data if it did root your phone you may only be slightly better off!!?? But at least it should only be your user data they are gathering and not your bank account number to try and get ya money like the malware guys!
Anyhow happy for you if you really are free of malware and don't forget to change all your passwords for all accounts, your routers etc else you could be reinfected by the time you read this!
I would reflash the stock ROM to be sure (backup ALL your pics, txts address, whatsapp etc etc)
I would also be interested to know how the app worked, if you can explain it. Did it say it would ROOT your phone? (there is nothing in their write up to say it will, Google would not allow an app that can root on play store, as far as I know) Do you have an app that can read what system apps are installed, like Link2sd? Does that show any of the malicious apk?
Thanks, No I did not root my phone but judging by the way removal came (easy) I too was bit surprised with outcome. No sooner I decided to remove the cm app Trojans and malware again became evident meaning it was just being suppressed in a way not removed and now again came back (when removed).

Sorry to hear this. However I think it is possible that the CM app did its job as those malicious apps have probably already rooted your phone, so CM may have just used that root access without informing you, though whether or not other apps like CM app can still use that root, I'm not sure, it depends if its been left "on". I did watch a video on youtube for CM Stubborn Trojan app and the guy had to root his phone first. (You could try some/several of the root checker apps, if you want to know). So lets assume the CM app worked properly and removed trojan as it could get root without giving you a root request notification.
It's entirely possible that your reinfection is from your external SD card or via some other means eg. your router has had some ports opened or some other means. (Sorry I should have said reset router when I said change router password [do this for all routers you use & update firmware & ensure remote access is off (ref. dirty cow) while you are about it too!]
So I would reinstall CM Stubborn Trojan (lets assume it removes malware as it has root, even if it just blocks them it helps us) so you can then reflash official stock ROM for your country (& update to newest version if available), you must flash the FULL stock ROM so all partitions are reflashed. partial stock or custom ROM will not do this & potentially leave you open to reinfection! Reflash the FULL STOCK ROM is the only way to "easily" be sure you have cleaned the malware from your phone. NOTE: just doing a factory reset will NOT remove the malicious apps if they are in operating system folders, this only works for malicious apps in user data areas! Then you must make sure all possible ways you can be reinfected eg via sync, external SD cards or storage, your PC, router etc are cleaned/blocked/reset/updated
If you are not getting updates for your ROM you might want to consider installing a custom ROM (AFTER you have flashed the stock ROM!) from a reliable & trustworthy source, if available for your model, so that you get security patch updates. But you need to research and consider the risks of things like bricks, security etc for yourself first.
Hope this helps you clean your phone
Sometimes, it's times, it's the firmware itself that is infected

In my case, I have a similar issue - however, it's an infected SYSTEM file - which Malwarebytes spotted (but is unable to remove), and is NOT related to the KingRoot dodgy file. It's actually two different Trojans - both in /system/priv-app (settings.apk and smsservices.apk) - the first is the more problematical. (It's problematical because it's a critical system file/app/service - killing it without a replacement is NOT an option.) How the heck do you replace such a critical system file when it got itself hijacked?
In this case, I would agree with just a complete factory reset or ROM reflash. Like it is simply too much of an issue to try removing and recovering everything. Especially, once it's deep within your system....

This was what I did finally, I went to service centre and spent bucks. They reloaded the firmware I suppose ( not flashing it) and instantaneously it was as good as new. I think, malware was itself part of original installation like uc browser- it was there. It just activated after some time or may be I clicked on some advertisement while running app and then the hell happened.
Any ways, its working fine, added an adblocker, restricted usage to few apps and keeping my fingers crossed for future.

Yeah, the bloatware that you get with some phones nowadays is unbearable. If there is an option, go with a rooted phone, custom ROM, some couple custom solutions for protection and you will be good to go. And they work better than defaults most of the time. Good luck! Hopefully, we will only be hearing good news from you

Depends on where the application come from. Most apps from the Play Store are okay and if you want to uninstall something it's probably okay. Just don't go using adb and uninstall any system apps.

It can potentially cause undesirable changes especially if the app is poorly written.
Avoid doing so when possible by not uploading an app for no good reason.
Read reviews about an app first.
Even a Playstore app can cost you a hard reset... did 2 back to back recently caused by a launcher.
If an app is running poorly, uninstall it. Clear the storage for the app first.
Keep an eye on what your apps are doing in the background with data/memory/battery usage.
Don't side load apps unless you -really- trust the source. If so -always- scan it with an online scanner like Virus Total before you install it!!!
Use SD Maid to pick off the remnants of uninstalled apps.

As I said apps from the Play Store are mostly safe as they are constantly being checked by Google. Every once in a while something will slip by but mostly safe. If you are worried activate device security in settings under device care.

Just because an app is "safe" doesn't mean it isn't poorly coded. Bad uninstalls is more a PC issue but Androids aren't completely immune to it.
Just one change hidden (inaccessible) setting change can really screw up your machine. Saw that happen on an e-reader; it globally changed the screen tint and when uninstalled it remained. Had to reload it, toggle that off, uninstall. The was a bloody Goggle apk.
Be it a trojan or bad coding a hard reset is a hard reset.
It's rare for a Playstore Android app to crash and burn the OS but it definitely does happen
As do buggy uninstalls... best not do too many installs or uninstalls together so if there is an issue you can spot it and know where it came from.
This may be the only way to easily correct it...
thank you
