About DeepGuard

When a file or program is first launched, F-Secure's security programs verify its safety from the Security Cloud file reputation service. If it cannot be verified, DeepGuard starts to monitor its behavior. DeepGuard automatically blocks files or programs that try to make potentially harmful changes to the system.

A script is a small program or piece of code used to automate minor tasks in applications or on websites, and to add extra functions or behaviors.

While scripts are often used for legitimate and helpful tasks, they can also be used in a harmful context to automate the tasks involved in installing or running harmful programs such as trojans or exploits.

Scripts can be written in many languages; one of the most commonly used is JavaScript (JS). Many webpages include JS scripts to add interactivity or improve their usability.
