Dubbed xHelper, this malware isn’t so much about stealing your phone’s information or sensitive details, but rather, it is designed to continuously serve up popup ads, in which presumably that is how its creators are making money off it. There is one particularly dangerous feature of the malware, which according to ZDNet, would see the malware download and install apps on your behalf.
As if that wasn’t bad enough, as we said, the malware cannot be uninstalled or removed even if you factory reset your phone. According to security companies like Symantec and Malwarebytes, they believe that the reason why this app is so persistent is because of a system app that might have been compromised.
Given that system apps are usually reinstalled upon a factory reset, it means that even if the malware has been removed, the system app would redownload it again. There doesn’t seem to be any particular way of preventing the malware from being installed, so your best bet would be to avoid suspicious downloads and websites until a solution has been found.
