Backdoor.Usinec.A

Backdoor.Usinec.A is a backdoor Trojan that has been created to steal private information and send it away to a remote server. It can connect to a remote server to receive instructions, and then later download other arbitrary files and install them onto your system. Backdoor.Usinec.A is a very cunning parasite because it enters your system in secret and it does not manifest its presence in any visible way. You can only determine the infection by the files that get installed in the Windows system folder.

The most obvious infection files are inusbw32.dll and ntusbw32.dll. These dynamic link library files can tell you a lot about what Backdoor.Usinec.A can do, especially as they are classified as backdoors that can allow other malicious software to enter your computer in no time. The most important thing is that Backdoor.Usinec.A can start working at once, because the moment it is installed in your computer it adds certain keys to the registry that allows the Trojan to load automatically every single time you turn on your computer.

It has been observed that Backdoor.Usinec.A is installed as a Winlogon notification package which means that this parasite is executed in the same address as “winlogon.exe”. Winlogon.exe is a legitimate Windows executable that runs all of the time, and thus it can be inferred that by using the same address space as a legitimate process Backdoor.Usinec.A tries to conceal its presence and avoid detection by security products.

After the installation Backdoor.Usinec.A connects to a remove server (69.162.111.211) and then receives instructions how to download other files and inject malicious programs into processes that are already running. Backdoor.Usinec.A collects such personal information as the IP address, computer name, logon name, CPU type and then sends it away to a remote server. The Trojan also modifies Internet Explorer’s settings and lowers its security level and your browser becomes exposed to various infections.

To put it simply, Backdoor.Usinec.A is a dangerous parasite that crushes your system’s security and allows other dangerous programs to enter your computer. It also collects various types of information about your system and sends it away to its creator. If your computer is acting weird, it might be infected with the parasite and you need to download a reliable antimalware application which will help you to perform a full system scan and remove Backdoor.Usinec.A for good. Do not hesitate to invest in your computer’s security.
