Should be. Don't forget to scrub out free space too, in case the file moved around before you wiped it.

My little advice for anyone in the future. If should you inadvertently downloaded one of the mislabeled files which turned to be a child pornography material - please immediately report it to the Cybertipline and law enforcements.

The computer crime investigator at my local police department (He is also part of my local county's procuestor office's computer crime unit) strongly recommend it to anyone. It happened to me once before in the past and I did what they recommended. Not reporting it is very worse thing that anyone could do in that situation, so please do the right thing. They will know what to do when you report to it and you wouldn't have to worry about get in the trouble because you reported.

Please report it or contact the proper authorities so you could get these sick scums off the P2P networks and internet.

Recommendations by many organizations including FBI which I posted in another thread awhile ago -
