ComboFix is one of the most powerful tools one can ever use to combat persistent virii and malware but at the same time is also a very dangerous tool to use as it can mess up a system rendering it unusable if used by an inexperienced user.Unfortunately it was discovered on January 29, 2013 that a compromised version of ComboFix laced with the Sality virus got uploaded on bleepingcomputer as well as other system recovery community sites that mirror the tools for helping out people who have pesky computer virus and/or malware issues.It is a bit alarming that people who create virii are actually able to crack sites like bleepingcomputer now and inject nasty stuff on tools designed to remove their handy work.Source ---> http://www.bleepingcomputer.com/forums/topic483431.html
Unfortunately it has come to light that the program ComboFix had a file in it that is infected with the Sality virus. The minute we heard about this, we pulled the executable so that it is no longer available from BleepingComputer.com. Unfortunately we have no control over other sites that may have mirrored ComboFix without permission, so please do not attempt to download it elsewhere.The developer, sUBs, is currently looking into what happened and when I have a full update, I will be sure to let you know. From the limited information that I have, it appears that the affected version has been available since approximately 2am EST on January 29th, but it may have been earlier. If this timeframe changes, I will update this topic to let you know. If you have used ComboFix in the last day or so, then you should examine your system for possible infection. If you have used a copy of ComboFix prior to this version, then you should be ok.SHA256 Hashes of known affected versions are:4524611a78ddd40afa7e13238da230302786c546d1f824e6e7dea480a5d55333

As the Sality infection has been around for a while, almost all antivirus vendors will have detected it and blocked it when you ran ComboFix. Unfortunately, not everyone has up-to-date virus definitions or uses an AV program, so it is important to examine your system if you have used CF since 2am EST.The steps we suggest you take to make sure your computer is not infected are: Scan your computer with ESET's Online Scanner. [Temp Locally Hosted Version] Download and scan your computer with the Kaspersky Rescue Disk [Temp Locally Hosted Version] Use SalityKiller if you are unable to use the above tools for some reason. When using this tool, you should disconnect from your network first. [Temp Locally Hosted Version]All of these tools should be able to detect and remove Sality from your computer. Sality is also able to spread through mapped network drives and shares. If you share any folders on your network, you should perform the above steps on those computers as well.If you need help with any of these steps, or would like us to check your computer, please feel free to ask us in the forums. You can either post in the Am I infected? forum or create a virus removal assistance topic in the Virus, Trojan, Spyware, and Malware Removal Logs forum using these steps.We are here to help you, so please do not hesitate to ask.I sincerely apologize for any issues this may have caused and assure you that we will do our utmost to help anyone who may have been affected by this situation.Lawrence Abrams

Reason for edit: Added Hashes
EDIT: Addendum:But there is good news....On the second page of that thread an Admin of BleepingComputer has notified the community that the creator of ComboFix has finally done fixing up the tool so boo~yah~!EDIT: Addendum yet again:And... it seems Subs (the creator of ComboFix) was the one at fault, or rather his defective mouse (as he states on the very same thread) so yeah... major oopsie moment there.

Shucks, I understand how guilty that might have been for him.
