About Scripts

In computing, ascript is a small program or section of code which is 'read' and executed by another, primary application. Scripts can be written in one of a large number of programming languages (e.g., Bash, Delphi, JavaScript, etc), and may be used to perform a wide variety of actions, making them versatile tools in legitimate circumstances. Unfortunately, this versatility may also be put to use with malicious intent.

Malicious scripts are usually (but not always) detected as trojans. Examples of malicious scripts include:

About Generic Detections

Unlike more traditional detections (also known as signatures or single-file detections) a Generic Detection does not identify a unique or individual malicious program. Instead, a Generic Detection looks for broadly applicable code or behavior characteristics that indicate a file as potentially malicious, so that a single Generic Detection can efficiently identify dozens, or even hundreds of malware.
