TDL3 rootkit still large issue for anti virus programs

Occasionally a new virus appears that is clever enough to completely deceive anti virus programs. TDL3, a variant of the TDSS rootkit (also known as Alureon) is such a sophisticated virus and it is causing sleepless nights for anti virus researchers.

The first variant, TDL1, appeared in the summer of 2008 and is still capable to prevent detection by many anti virus programs. In the summer we saw the 2nd variant TDL2.

TDL3 shows clearly how the malware industry has grown into a money driven industry. The writers of other viruses like the so called Google Redirect Virus can pay the authors of TDL3 to upload their virus to TDL3 infected users.
