“Attempting to close IE window (IE 8), got a fake Windows message – your computer is infected. I went to Task Manager, ended the IE and Message programs and immediately shut the PC down…”—- A victim describes how he get infected Trojan:Win32/Sirefef.K Virus. People often don’t know how to start to clean such Trojan virus. Here, a practical solution is stated as follows.

Nature of Trojan:Win32/Sirefef.K

If have to give a classification of such Trojan as Trojan:Win32/Sirefef.K, it belongs to rootkit that is bundled with Trojan:Win32/Sirefef.AG. A rootkit is a collection of one or more tools designed to covertly gain control authority of a computer. Trojan:Win32/Sirefef.K is a component of Win32/Sirefef – a multi-component family of malware Trojan.Win32.Sirefef (Ikarus); Mal/Sirefef-K (Sophos); TROJ_SIREFEF.CL (Trend Micro) that moderates an affected user’s computer performance and picked up by Microsoft Security essentials(MSE).  Initially rootkits appeared on the UNIX operating systems (including Linux) and were a collection of one or more tools which allowed an attacker to gain and keep access to the most privileged user on the computer (on UNIX systems this user is called ‘root’ – hence the name) On Windows based systems, rookits have more commonly been associated with tools used for hiding programs or processes from the users. Trojan:Win32/Sirefef.K also belongs to a Trojan dropper. A dropper Trojan contains malicious or potentially unwanted software which it ‘drops’ and installs on the affected system. Commonly, the dropper installs a backdoor which allows remote, surreptitious access to infected systems. This Trojan:Win32/Sirefef.K backdoor may then be used by remote attackers to upload and install further malicious or potentially unwanted software on the system. This threat is detected by the Microsoft antivirus engine. Technical details are not currently available.When installed a Windows rootkit uses functions in the operating system to hide itself, so as not to be detected, and is often used to hide other malicious programs such as keystroke loggers. The use of rootkits is not necessarily malicious, but they have come to be increasingly associated with undesirable behavior and malicious software. All bundled malware and these malicious dropping codes can hide in your system, processes, program files, dll files and folders to damage your PC system seriously. In such cases, it is very difficult for antivirus tools to detect all infected items and eliminate them from your PC completely. If your PC has been infected Trojan:Win32/Sirefef.K virus, please spare no effort in seeking solutions to delete is forever! Read the rest of this post »
