The well known TDL4 Rootkit has been deemed indestructible by Kaspersky Labs researcher Sergey Golovanov. He goes on to say that it is “the most sophisticated threat today”

It attaches itself to the MBR or boot portion of the hard drive at sector 0 and remains hidden until it is called upon with instructions on what to do. It is not detectable by any of the store bought anti-virus software’s that are in use by most PC’s today.  You won’t even know you have it installed other than you may notice a slow down in your connection if the botnet decides to take action on a target.  When it does take action, your computer will be a part of the army of about four million PCs that have been infected.

TDL-4 itself downloads and installs other malware as well as gets rid of malware it doesn’t want on the computer. The most popular one that it installs is “Fake Anti-virus” scareware.

Here comes the good part though. We offer FREE detection to make sure you don’t have it on your system. Computer Whisperer also has special software to get rid of the TDL-4 Rootkit as well as anything it added to your computer.  We are the only repair shop to have this ability in the area.
