Rootkit.TDSS is a malware which spreads its infection through peer-to-peer sharing networks or through corrupt websites that carry malicious freeware. Known also as TDL3 and Alureon (Microsoft), this spyware is known to operate through stealth techniques, making its detection and removal highly difficult. Rootkit.TDSS is the third variant of the TDSS rootkit family that has compromised computers – specifically those running under Microsoft Windows – around the world. The workings of the TDSS malware are no different from its earlier TDSS variants as well as other rootkits such as MBR rootkit and Rustock.C. The rationale behind the creation of Rootkit.TDSS is for its creators to be able to exercise control of the infected PCs and to facilitate fraudulent online activities. These activities range from financial information and password theft to DOS or Denial of Service attacks.

Detecting a Rootkit.TDSS Infection


Cyber criminals are known to use rootkits in order to keep their Trojan activities covert. Since rootkits are designed to evade detection from computer users and even from anti-malware software, most victims are unaware on the real state of their PCs. There are several signs that point to an existing Rootkit.TDSS infection and these include browser redirections, blocking of security websites, slow-loading web pages and inability for the PC user to launch an anti-malware program. Essentially, Rootkit.TDSS behaves like any other malware, except that Rootkit.TDSS is written in such a manner that detection becomes almost next to impossible. The installation of a rootkit like Rootkit.TDSS is made easier through PC users that log into their computers casually, imposing no access restrictions whatsoever.

Rootkit.TDSS is also known to assist in the establishment of a botnet. By maintaining a botnet, which is a network of computers controlled by a host computer using a corrupt program, cybercriminals behind Rootkit.TDSS are able to carry out a host of activities related to online fraud. This allows them to spread the malware infection more conveniently and to intercept Internet traffic so as to steal passwords, user names and credit card numbers. Through the botnet, hackers are also able to carry out a DOS attack, which prevents a server or network resource from functioning optimally.

Rootkit.TDSS Removal


The spread of Rootkit.TDSS is prompted by peer-to-peer networks that allow for the downloading of corrupted shareware or software. Drive-by downloads, which contain this rootkit component, find their way into PCs without asking for user permission. Simply uninstalling Rootkit.TDSS is not likely to remove the infection completely, since this malware may reinstall itself even after Rootkit.TDSS has already been removed. Having spawned several versions such as TDL-4, which is a 4th generation variant of the TDL malware, it's likely that Rootkit.TDSS has already found its way into a high number of machines.

Nonetheless, eliminating Rootkit.TDSS should be done right away after its detection. The removal of Rootkit.TDSS depends on the use of legitimate anti-malware tools, while its prevention rests mainly on responsible web browsing and file-downloading practices. While complicated, the process of deleting Rootkit.TDSS should be a priority. Legitimate security software will eliminate the Rootkit.TDSS infection completely and restore computer settings, to ensure optimum PC function.
