If any infections are found in TDSSKiller, please follow the instructions and reboot when asked. I will go over removal methods of the rootkits commonly associated with this infection in other posts.
Last step is to use your favorite malware scanner to ensure all traces have been removed. MalwareBytes' Anti-Malware is my favorite. Make sure that you run a full scan to ensure that you have removed items from all user accounts and system restore.
Some of these have a worm infection called Parite. You will find the infection in the log file of the MalwareBytes' scan that you just ran if it is present. This can be removed by using the BitDefender Parite Removal Tool.
Finally, do yourself a favor and create a restore point ;)
