What is Malware DLL File?
A DLL (Dynamic Link Library) file is an executable file that allows applications to share code to perform one or more predetermined functions. One of the biggest advantages is that a DLL isn't loaded into RAM, saving memory and enabling multiple programs to function efficiently. Most DLL files are very useful and aid in the process of running your applications. However, others are malicious, acting as browser hijackers or Trojan horses. These programs can alter your system and allow intruders to gain remote access to your system.
Dangerous DLL Files
Spyaxe is one such program that makes use of malware DLL files. It is a member of the Smitfraud Trojan family and their known lineup of rogue anti-spyware products. These products often work in conjunction to trap their victims. One displays the fake spyware alert and offers the solution. The other installs the Spyaxe application consisting of an infected media codec. The media codec supposedly allows you to view multi-media content. However, the application is not a useful plugin, but actually a Zlob Trojan horse.
The Zlob Trojan poses a serious threat because it has the ability to download various malware DLL files onto your system. Like most Trojans, the impact of this program varies, depending on what else it installs on your computer. It may run executions from the rogue spyware application and display pop-up ads or completely take over your entire system. This program is very dangerous and should be avoided due to the great potential for abuse.
Spyaxe and other Trojans like it are well known for installing other malware DLL files. They use random file names and secretly drop them into the Windows system folder. From there, entries are made in the registry to enable the automated execution of malware DLL files upon each system startup. They can also register themselves as BHOs (Browser Helper Objects) to ensure an automatic execution each time the Internet Explorer browser is run.
Removing Malware DLL Files
You should proceed with caution when attempting to remove malware DLL files. You can begin with the "Add/Remove" utility in windows. Many applications come with an uninstall function that may remove unwanted DLL files. Keep in mind that the utility may assume that some files are shared and will not have a way of knowing the other programs that use them. This often results in DLL files being left on your system, recreating the malicious program upon a reboot.
One effective way to remove specific malware DLL files is to use the Regsvr32 utility. This tool is built into the Windows operating system and is designed to register and unregister DLL files already on the computer. There are numerous programs available for this task, but Regsvr32 is one of the most common.
Although Regsvr is a useful tool, it's not the recommended method for removing malware DLL files. The best solution involves using a reliable anti-malware product. This type of software has the ability to surf deep within the system folders and registry of your computer.
