Computers create records in hundreds of ways of everything you do on the computer and on the internet.
If you are in danger, please try to use a safer computer where someone abusive does not have direct access or remote (hacking) access.
It might be safer to use a computer in a public library at a community technology center (CTC) www.ctnet.org for a national directory, at a trusted friends house, or at an Internet Cafe.
If you think your activities are being monitored, you are probably right. Abusive people are often controlling and want to know your every move. You don't need to be a computer programmer or have special skills to monitor someone's computer activities-- anyone can do it and there are many ways to monitor.
Computers can provide a lot of information about what you look at on the Internet, the emails you send, and other activities. It is not possible to delete or clear all computer "footprints".
If you think you may be monitored on your home computer, consider no home internet use or "safer" Internet surfing. Example: If you are planning to flee to another state, don't look at classified ads for jobs and apartments or bus tickets for that state on a home computer or any computer an abuser has physical or remote access to. Use a safer computer to research an escape plan.
