VeraCrypt

• VeraCrypt: Eraser and DBAN need time to erase but usually there is no time when the police got search and seizure warrants. So you should encrypt your computer using an encryption software such as VeraCrypt. When you use Windows, you must encrypt your C: drive also because of cash and temporary files. And you can use hidden volume if you want to avoid the police's threat and torture to reveal the encryption password from you. https://www.veracrypt.fr/en/Home.html
