Comprehensive Guide to Detecting and Removing Trojan.Script.Obfus.Emsr Malware

Trojan horse malware, commonly known as “Trojans,” are deceptive threats designed to infiltrate computers by masquerading as legitimate programs or files. Named after the ancient Greek tale of the Trojan Horse, these threats sneak into systems under the guise of safe or useful applications. However, once inside, they wreak havoc on both system operations and user data, often compromising sensitive information or installing additional malware. Trojans typically enter a system via phishing emails, malicious downloads, or exploited software vulnerabilities. These threats pose significant risks not only to the infected system’s integrity but also to the privacy and security of individuals, often resulting in data theft, credential leakage, or unauthorized remote access.
