no it doesn't. since KillZA is obsolete now, guess it doesn't matter if I post the tricks of the trade. it only removes whatever directory/files are found referenced in one of two reg locations where those variants plant themselves. The directory is usually inside the recycle bin and the files are (I think) always the same, like there's one just named 'n' and a few others.
(both keys are legitimate in HKLM but neither are legit if found in HKCU...)
I think if you use Bitdefender's tool or that other one I forget but one or both of them will remove the files and maybe other reg entries, but not these particular reg entry points so this is why KillZA may 'find' the infection after it has been removed by another tool.
