<p>I second what franglish said about the LoJack for Laptops. It’s simple-to-install software that runs in the background so theives can’t uninstall it without the installation code. If your laptop is ever stolen, simply alert the police and LoJack, and their technicians will send a code to the computer the next time the thief accesses the internet. This will give them the location where it is being used, allowing the police to retrieve it.</p>
