ComboFix rootkit infection

I just fixed a malware problem (I think) using ComboFix and a script file that was posted here . I posted the problem and fix on another forum since I believe the malware was from the other site and others were probably infected.

I got this reply from one of the members:
***************
The creator of ComboFix, sUBs, has encountered a Rootkit that will cause ComboFix to recursively delete all files from SystemDrive.

This is what he had to say:

Pulling the tool till further notice.

Please inform your users not to use CF. Who knows if that rootkit is in there.

Please spread the word. Also have users delete their copies of CF
If you try to download ComobFix, you will only receive a text file saying:

The tool, ComboFix has been temporarily withdrawn.

The author discovered a rootkit infection that will intefere with ComboFix's running.

This will cause Combofix to be UNSAFE FOR USE on your machine.

Even if you manage to find a mirror for the tool, PLEASE DO NOT RUN THIS TOOL

Apologies for any inconvenience caused
If you have ComboFix present, please delete it from your computer immediately.

Is there anything to this. Trust me, I searched this site before I posted this thinking that if this is real, one of you guys must know about it since ComboFix is widely recommended here. I'm new to this site and hope I'm not re-hashing old news.

Thanks in advance...
