I worked with Malwarebytes on this problem and at the time Malwarebytes wasn't detecting it, but I knew that I had Adups because of the browser hijack. If you look at your apps list you should see a green icon with a yellow center with an arrow or something called "Wireless Update" and within it is another app called "Hidden Menu" I tried to remove it by following the "How to remove adups" above, but it didn't work. They figured out the "real names" of the app. When I first went through the removal, I think the browser hijack came back, but I reset my phone to factory settings and immediately went through the procedure and the past few days I haven't seen any sign of it.
You need to use a pc, mac or linux computer to execute the commands over USB to your phone after setting it all up in developer mode as described in the memo above. But the important thing was knowing what to target. So if you have ADB on your computer and your phone all ready to go, these are the commands that I entered:
Okay, I got:
com.dtinfo.tools Wireless Update
To remove, you would use this command:
adb shell pm uninstall -k --user 0 com.dtinfo.tools
As far as HiddenMenu, use this:
adb shell pm uninstall -k --user 0 com.teleepoch.hiddenmenu
Apparently if you reset your phone, it will all come back since they are system apps so if you ever factory reset your phone you will have to do this again. Once you uninstall it, it will still appear in your apps list but it will say uninstalled for this user.
