How an abuser can discover your internet activities

Email: If an abuser sends you threatening or harassing email messages, they may be printed and saved as evidence of this abuse. Additionally, the messages may constitute a federal offense. For more information on this issue, contact your local United States Attorney's Office.

History / Cache file: If an abuser knows how to read your computer's history or cache file (automatically saved web pages and graphics), he or she may be able to see information you have viewed recently on the internet. You can clear your history or empty your cache file in your browser's settings.
