Trojan-Downloader.MSWord.Agent.jk is a Trojan that may install other threats onto your computer. A threat delivery system like Trojan-Downloader.MSWord.Agent.jk may disguise itself as a benign or harmless file, such as a document and may be distributed via both e-mail spam and corrupted websites. Since a Trojan-Downloader.MSWord.Agent.jk's payload is not necessarily readily visible, any process of deleting Trojan-Downloader.MSWord.Agent.jk should include broad anti-malware solutions that can identify any other threats that Trojan-Downloader.MSWord.Agent.jk may have installed.

The Hidden Content in a Word Doc

Trojan-Downloader.MSWord.Agent.jk, sometimes incorrectly identified as a variant of the BrowseFox adware, is a Trojan that downloads and installs other threats onto your system. Trojan-Downloader.MSWord.Agent.jk may be found as part of a Microsoft Word document, such as a .DOC file, with embedded, toxic content. PC users who open Trojan-Downloader.MSWord.Agent.jk without any additional protection may allow Trojan-Downloader.MSWord.Agent.jk to install other threats of variable types. In the past, malware experts have seen such attacks primarily responsible for delivering sophisticated, multiple-component threats, such as banking Trojans, other spyware, rootkits and backdoor Trojans.

As a part of its disguise, Trojan-Downloader.MSWord.Agent.jk (with aliases including W97M/Adnel, Trojan.Script.Agent.drhvbn, and W97M.Dropper.FE) may include some legitimate text or image content. However, VisualBasic macros, threatening scripts and other, hostile content are not necessarily loaded with any visible elements. The visual flexibility of this attack could allow Trojan-Downloader.MSWord.Agent.jk to launch attacks without alerting the PC's user, after which, the negative consequences are equally flexible.

Modern versions of Microsoft Office are designed to warn the user before enabling any exploitable, out-of-date content, such as the macros used by Trojan-Downloader.MSWord.Agent.jk. However, PC users with old versions of that software or lax security settings may be more vulnerable than usual to an automatically launched attack. Many, but not all anti-malware products also include features capable of identifying these threats in the act.

Cutting the Words of a Trojan Agent Short

Trojan-Downloader.MSWord.Agent.jk and Trojan downloaders like Trojan-Downloader.MSWord.Agent.jk may be circulated as e-mail attachments, with disguises ranging from invoice notifications to fictitious shopping transactions. Malware researchers have seen similar threats used against both the general public and against specific, targeted entities, such as NGOs, government agencies, and corporations. Accordingly, scanning a suspicious e-mail file before opening it is an essential step in maintaining your PC's security, no matter what the purpose of your machine might be.

If you've already opened a file that's identifiable as Trojan-Downloader.MSWord.Agent.jk, your PC is likely to be infected with other threats with greater capabilities than this specialized Trojan. When you're disinfecting a system after such an event, malware experts would particularly emphasize the need to block other infection vectors (such as shared USB devices) and protect any potentially collected information. Such simple steps can help keep Trojan-Downloader.MSWord.Agent.jk from being a gateway into long-term problems with your bank account, network servers or removable devices.
