Trojan.Shylock is a hazardous Trojan that hijacks network traffic and tries to add malicious code to it. Trojan.Shylock involves rootkit capabilities to conceal its occurrence on the infected machine. When activated, Trojan.Shylock copies itself to a random folder with a random name. Trojan.Shylock then gathers data from the computer and creates a certain registry entry so that it could run every time you start your machine. Trojan.Shylock then uploads PC system information about the targeted host and downloads configuration data from one of certain web pages. Delete Trojan.Shylock before it destroys your computer system.
