Zlob.LH

Zlob.LH is a variant of a Trojan hailing from 2005 but is still a viable threat to your PC's security despite Zlob.LH's antiquated nature. The signature distribution methods for Zlob.LH and other Zlob-based Trojans are through fake codec downloads that pretend to be useful software updates. An infection by Zlob.LH is a serious compromise of your PC's security, since Zlob.LH can download and execute malicious files without your consent. Zlob.LH may also allow remote attackers to control your computer, with potential attacks varying from spying and keylogging to actively destroying the machine. Deleting Zlob.LH should be done through anti-malware software designed for the task since manual deletion can easily fail to remove the Trojan completely.

How Zlob.LH Got to You

The Zlob.LH variation on the basic Zlob Trojan was largely developed as a threat in 2006, with appropriate anti-malware software protections being developed in that same year. Although Zlob.LH hasn't seen any recent updates Zlob.LH may still circulate in some areas of the web, and new versions of the Zlob Trojan are also a threat.

The most well-known infection route for Zlob.LH is through fake codec updates. These fake updates are hosted on online video websites which instruct you to update your movie-viewing plugin to see the content. Downloading codecs and other updates through secure channels will prevent Zlob.LH and other malware from having an infection route to your PC.

Other versions of Zlob.LH-based Trojans may also infect your computer through fake JavaScript-enabled system scans, or be directly injected by malicious website code.

The major symptom of infection by Zlob.LH is the appearance of pop-up advertisements. These pop-ups contain links that enable the download and installation of rogue security applications. Rogue security programs will pretend to be useful applications while causing fake system alerts and other difficulties in an effort to snatch money from the user in a fraudulent registration process.

Putting a Stop to Zlob.LH

Even if one ignores Zlob.LH's pop-ups, there are other dangers that make removing Zlob.LH a good idea. Zlob.LH may download malware and install them on your computer without requesting permission or requiring that you click a pop-up, thus creating a complex multi-infection scenario.

Some versions of Zlob.LH may also have backdoor functions that allow remote attackers to snatch control of the PC right out of your grasp. Remote attackers can engage in virtually unlimited types of attacks, and may steal sensitive information, directly harm your operating system or force the PC to engage in DDoS attacks and other criminal activities.

All of these possibilities continue to make Zlob.LH a relevant threat in spite of Zlob.LH's age. Removing Zlob.LH should be done by a good-quality anti-malware scanner when possible, since Zlob.LH is known to hide in Windows system folders and use semi-randomized file names. Deleting the wrong file in a system folder can permanently damage your OS and should be considered only as a last resort if deleting Zlob.LH can't be accomplished in any other way.
