Disinfection & Removal
Obfuscated script is usually found in exploits embedded in malicious HTML and PDf files, which are commonly found in the wild; such files may have damaging payloads, such as downloading additional malicious files and executing it.
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.
