Mousetrapping

Mousetrapping is a technique that prevents users from exiting a website through standard means. It is frequently used by malicious websites, and is often seen on tech support scam sites.

Mousetrapping can be executed through various means. A website may launch an endless series of pop-up ads or redirects; it may re-launch the website in a window that cannot be easily closed. Sometimes these windows run like stand-alone applications and cause the taskbar and browser menu to become inaccessible. Some websites also employ browser hijackers to reset the user's homepage.
