Are these random UID applications spywares?

It's been a year since I am ignoring all these Applications using my data and battery. At first, I thought they could be apps that I uninstalled a while ago. But, no, every third day they were showing up in logs with the exact same UID, and if I restricted their data, then the next day they still showed up with another UID but used the same data and battery. No doubt these are spyware. If they're, then how should I get rid of these without a factory reset?
