[Silence]

As the title says, my girlfriend apparently got RATed. She's not sure if it's on her phone or PC, but several people sent her things that she sent me to her on Snapchat, saying she messaged them. Coming home to your girlfriend crying over this isn't exactly grand, so can anyone gives tips on the following:
- How can I find said pictures and see if they were uploaded online, she isn't sure if they were or not.
- How can the RAT(s) be removed from Win10 (Microsoft's Official Virus) as well as Android.
- Possibly find out the person who did this, whether by finding info from the RAT or any other possible way. Clueless as to who. 
- Also, do you think I would face charges should I find the person who did it and physically harm them. They distributed child pornography as well as infected a PC.
