It mentioned that I downloaded the following on Dec 11th:
1. Office 2016 Pro
2. Assassin's Creed Unity
3. Watchdogs
Not only is it completely inaccurate, no one used my internet on Dec 11th (which meant my IP was probably shuffled by my ISP to someone else).
This is one of the reasons why you should probably take all those DMCA notices with a pinch of salt...it's almost impossible to argue that you pirated in the first place.
