I checked the result of the cleaning tool (CS_DevEvil.zip). The virus is completely gone and even the hosts file was fixed.

Another thing, it's easy to see if the virus is still active on a PC by running Ad-Aware and then looking in the log file. If it's still active you will find some lines similar to this in the running processes list:
