How to Remove Hidden Spy Apps from Smartphones?

Greetings!

Recently, I noticed unusual activity on my Android phone. The battery was draining earlier, data consumption increased, and my phone was very slow. When I talked with IT expert of or department, he just referred me this blog to quickly detect the hidden spying apps on my phone.

I don't have a backup of all necessary files that's why I avoid factory reset. Can you refer any quick way to remove all hidden spy apps from my phone?

Your possible suggestions would be appreciated.
