UpgradeSys virus threatens Android users with Trojan features

UpgradeSys virus example

UpgradeSys virus is a pre-installed Android application which is usually found on mobile phones manufactured by BLU. Experts also categorize these types of potentially unwanted programs as adups. Even though there is not much information about this relatively new infection, it is already known that this PUP possesses similar features to a Trojan Horse[1].

Multiple antivirus tools detected UpgradeSys malware under the following names:

  • com.adups.fota;
  • com.adups.fota.sysoper;
  • FWUpgradeProvider.apk.

Since UpgradeSys adup is usually installed before the user purchases the smartphone, it is provided with the administrative rights. They allow it to install new applications and upgrade the old ones without user's consent or notice. Root access is highly dangerous since the potentially unwanted program might be programmed to download other hazards.

Additionally, UpgradeSys is able to monitor your text messages and other content stored on the device. This Trojan horse might even connect to the command-and-control server and sent the copied information to the authors of the virus. Also, it can take over your device and send texts itself. 

Furthermore, there are several reports which state the UpgradeSys malware can generate excessive amounts of intrusive pop-ups on your frequently visited websites. Even though it might seem only annoying, it is dangerous as well. Sponsored ads can lead you to bogus pages where viruses are distributed[2]. Likewise, you are put at risk every time you start a new browsing session. 

Therefore, we strongly advise you to remove UpgradeSys as soon as possible. There not much reliable information about its other features which might be far worse than the ones mentioned above. Note that this pre-installed application cannot be eliminated from the device manually. 

Thus, you can find UpgradeSys removal guide below. It will explain to you how to get rid of this malicious program without rooting your smartphone. You should be aware that currently, this is the safest option to clean your device from adups. We recommend you to stay away from any unauthorized third-party tools which might be designed to damage your phone even more.

How adups are installed on your device

According to the experts from DieViren.de[3], more and more devices sold online are modified for the malevolent purposes. Usually, the manufacturers re-image the Read-Only Memory (ROM)  with customized ones and sell the products on e-shops such as Amazon.

This modification can completely change the default operating system of the smartphone and contain malicious applications which after re-image are classified as pre-installed and cannot be removed/uninstalled. Likewise, just like you must download software from authorized developers, you have to purchase devices from reliable sources as well.

Note that the price of the damaged good is significantly lower than the original one's. Thus, do not get tricked by “great” deals or other offers. This low-price tendency is merely an attempt to lure gullible people into getting a malware-laden device.
