Detected Using Cheating Software?!?!

I logged in to the game today to be met with a message that I have been detected using cheating software such as maphacks or bots.

The only software I am guilty of using is the Sidekick app and the Overwolf Overlay, are these against the TOS?

I'm afraid to continue to play the game being accused of cheating, which could result in the banning of my account.

Provide some evidence?
