Android.Umeng is a known form of adware, a type of malicious software that runs on your computer to display unwanted ads without your consent. Android.Umeng is considered a web browser add-on - it is installed without your knowledge as a plugin or extension in your browser.
After installation, Android.Umeng starts displaying unwanted ads when you browse the Internet with your browser. This type of adware is not limited to displaying ads, but can also redirect you to other malicious websites and constantly display annoying popup ads.
The most common methods by which Android.Umeng can enter your browser are by accidentally clicking on "sponsored links", installing legitimate software provided with this type of adware, or installing an infected browser plugin or extension. Android.Umeng can also infect your computer if you open an email attachment or download a program already infected by Android.Umeng.
Once your computer is infected by Android.Umeng, it will immediately start behaving maliciously. In addition to displaying unsolicited advertisements, Android.Umeng may ask you to install false software updates or submit your personal and sensitive information for collection.
In addition, adware programs such as Android.Umeng can also change your browser settings. It is common for browsers infected by Android.Umeng to change their default settings in an undesirable way. In extreme cases, Android.Umeng can cause very serious damage to your system by manipulating the Windows registry and security settings on your computer.
Adware is a software application that displays banner ads during the execution of a program. Announcements are provided through popup windows or bars that appear within the program's user interface. Adware is often created for computers, but can also be found on mobile devices. The rationale for adware is that it helps to cover the development costs of the program for the software developer and to reduce or eliminate costs for the user.
Adware software generates revenue for its developer by automatically displaying advertising in the software's user interface or on a screen that appears on the user's face during the installation process. You can also open new tabs, see a change on your home page, see the results of a search engine you've never heard of, or even be redirected to a NSFW website.
Android.Umeng is sometimes integrated into freeware (free software) that a user has downloaded from somewhere. After installation, the user has the choice of continuing to use the software as is with advertising or purchasing an advertising-free version of the software.
Software manufacturers pay for ads to appear when you search for certain software. These ads will lead you to download software that may not even install the software you are looking for, but you will still receive adware. So, while you think that all you get is decent free software, what you actually get is a lot of ads.
In addition to replacing ads with yours and withdrawing money from search engines, adware will also appear with even more questionable offers, such as asking you to install an "update" for Adobe Flash. All this for something that the customer could download for free from the right site. No part of the revenue goes to the free software developer; in fact, their reputation has probably been damaged.
If you suspect that your computer is infected with adware, look for any of the following signs:
Disconnect from the Internet
Close all open browser windows and applications (including email), then disconnect your computer from the Internet. If you are connected to the Internet via an Ethernet cable, the easiest way to disconnect is to simply remove the cable from your computer. If you are connected via Wi-Fi

In this step, we will try to identify and remove any malware that may be installed on your computer.
In the following message box, confirm the uninstallation process by clicking Yes, then follow the instructions to uninstall the program.
Even if the above step worked for you, chances are that the adware has already infected your browser and the uninstallation of the program does not get rid of ads. To clean the browser, simply reset its search engine (if it has changed) and search for extensions or add-ons that you do not recognize.
To reset the search engine:
To search for an adware extension or add-on, I recommend that you use a third-party tool that displays all extensions and plug-ins of all your browsers in a single window, including those that are hidden.
There was a similar duplicate with the same timestamp in the following directory - Internal storage/Android/data/.um/sysid.dat
I did a google search, and a Dr. Web page as well as a Hybrid analysis page came up, both flagging a similar directory as a SMS spy app. The files were same, but the directory was a little different, as they were located on the sd card in the pages, while in my phone they are located in Internal storage and no such files on sd card. Here is the link - https://vms.drweb.com/virus/?i=15272609&lng=en
I don't know how these files got in, as I haven't installed any new apps in like forever, and also I'm very cautious while browsing, and when these files got created, I was browsing perfectly safe websites. Anyway, since the Dr. Web page had the spyware sample and said it was able to flag the file, I figured the antivirus could at least detect the malware, if not remove it (in case it was rooted in the system), and hence downloaded the Dr. Web Light app from playstore and ran both full and quick scans with it, twice. Did not detect a thing, despite having these file directories explicitly listed on their website analysis of the spyware. I would understand if it did not remove it, but since it has already analysed this malware sample, I would expect it to at least flag the file.
Also ran full scans with Norton, Kaspersky, Sophos, Zelmana and F-secure (all free versions except Norton and Zelamana which gave Premium trial versions), none of them even detected anything.
Apart from the Dr. Web and Hybrid Analysis pages, there is no more information about this on the Internet, except a lonely reddit thread which point back to the same aforementioned pages.
Can anyone guide me in the right direction here? Anyone happen to know about this particular incident? What should I do? Factory reset? Firmware flashing? It will probably take me a couple days to do either because I have to back up personal documents, till then, should I refrain from using the phone? Turn off data connection? Or shut the phone off altogether? Not make any calls or send any sms? I only have this one phone, I'm signed into every which thing from this, and I receive and make calls and messages daily.
