Trojan-Downloader.JS.JScript.k

By Sumo3000 in Trojans

Trojan-Downloader.JS.JScript.k is considered a high risk and should be removed immediately, unless you want some hacker quietly stealing data and using your system to harm others.
 
Trojan-Downloader.JS.JScript.k executes Java Script to carry out its evil mission. The Trojan-Downloader.JS.JScript.k might be housed on malicious or compromised websites, in hopes of a visit from its new victim. All this infection requires is a visit so Trojan-Downloader.JS.JScript.k can 'drop down' and infect a computer system.
 
If your computer system is not well guarded, meaning you are not using stealth anti-malware protection, your data and PC will remain at risk and your identity amongst other valuable data could be stolen. Cybercriminals study social engineering to learn new ways to deceive humans and get them to 'click' and download programs. In the case of Trojan-Downloader.JS.JScript.k, you may have fallen victim to a dubious link on a Google or other search engine results page that delivered or directed you to the malicious web page housing Trojan-Downloader.JS.JScript.k.
 
Security experts who track malware and malicious activity in the wild (i.e. on the Internet) noted the Trojan seeks the name of the browser and OS, so Trojan-Downloader.JS.JScript.k can execute the malicious code in the browser. Notes indicate all browsers are vulnerable except 'WebKit.' Once Trojan-Downloader.JS.JScript.k verifies a suitable match, Trojan-Downloader.JS.JScript.k seeks cookies identified as 'UrlInfoCookie' and if unfound, Trojan-Downloader.JS.JScript.k creates such a browser file with value of 'OK' and expiration of 7 days. Next, Trojan-Downloader.JS.JScript.k makes contact with an external server at hxxp://urlsinfo(dot)com/in.cgi?9 (or other URL) to execute malicious Java Script.

Other than a stealth scanning tool, you may not notice your system has been infiltrated.  If confronted by a scanning engine or a fake interface selling some rogue security program, do not purchase anything you did not load yourself. Rogue security programs are intended to scare you into believing your data and system are at risk and that you need to buy a fraudulent program to combat the fake problems.
 
At the first hint of an intrusion, you need to act swiftly to find and remove all viruses. Infections travel in packs and can overload your system resources and cause an undue system crash. Furthermore, if your system is suddenly running slow, a hacker may be secretly using your resources to launch a DNS attack or mass email spam campaign. Either way, you don't want to part of some illegal act by some greedy cybercriminal.
 
Not all infections are easy to find and remove. Infections fortified by a rootkit can be masked as system, registry or .dll directory files. Deleting the wrong files could shut down your OS and system and could erase your valuable data. This is why security experts suggest using a reputable anti-malware tool to find and safely remove viruses hiding out deep in your system.
 
Until your system is free of Trojan-Downloader.JS.JScript.k or any other malware Trojan-Downloader.
