The TDSS Rootkit has become extremely widespread since TDSS Rootkit's beginnings in 2008. PC security analysts indicate that this rootkit presents exceptional difficulties for TDSS Rootkit's study and treatment because of TDSS Rootkit's very nature. The TDSS Rootkit infects drivers, meaning that TDSS Rootkit is loaded before the operating system itself. This implies an infection that is very deep and very challenging to remove. Usually, specialized tools are needed to detect and remove the TDSS Rootkit from an infected computer system.

The History of the TDSS Rootkit
The first versions of the TDSS Rootkit are known as TDL-1 or Rootkit.Win32.Clbd.a, because of TDSS Rootkit's ability to infect the driver clbdriver-sys and the clbdll.dll DLL file. Some parts of the original TDSS Rootkit remain in today's newest versions of this extremely dangerous infection. TDL-1 has the capability of hiding itself and other files, executing high-level functions, and injecting malicious code. The TDSS Rootkit also protects itself by displaying an error message reading "STATUS_TOO_MANY_SECRETS" when trying to open the directories needed to remove this rootkit.
The next version of the TDSS Rootkit, TDL-2 made its appearance in spring of 2009. Its main feature is that the rootkit was encrypted to make it much harder for security researchers to analyze TDSS Rootkit. The hackers behind the TDSS Rootkit also included random segments from Shakespeare's Hamlet to confuse researchers further.
In the autumn of 2009, the next generation of the TDSS Rootkit started appearing. Security researchers indicate that the TDL-3 generation of the TDSS Rootkit is particularly malignant and especially hard to remove. The main trouble with TDL-3 is the fact the hackers behind it update TDSS Rootkit constantly. There is a constant arms race between the PC security experts and the hackers; with each advancement in anti-rootkit technology, the hackers release a new update to undo it.
The TDSS Rootkit and Online Scams
Hackers use the TDSS Rootkit to make money through affiliate marketing. While affiliate marketing can be a completely legal activity, the hackers' version of affiliate marketing involves attracting visitors and unwary victims to infected websites associated with various kinds of malware. The TDSS Rootkit is also strongly related to large botnets, typically with a number close to twenty thousand infected computers, which are sold or rented out to criminal organizations. The creators of the TDSS Rootkit are thought to be from the Russian Federation. The TDSS Rootkit botnets have been used for a wide range of criminal activities, from DDoS attacks to sending massive amounts of spam emails.
