There is not a virus in the program but you should not use ComboFix unless directed to by somoene here trained in its use. Using it on your own could lead to problems resulting in your compter being rendered useless. If you think you are infected and in need of that program, make a post in the "Am I Infected" forum and let them guide you in cleaning up your machine.

Again, do NOT use ComboFix on your own

Combofix is available for those getting assistance by experts in the HijackThis Logs and Malware Removal forum.

Why for only those members?

It is a powerful tool intended by its creator to be "used under the guidance and supervision of an expert", NOT for private use. As such, no one should be using Combofix unless instructed to do so by a Malware Removal Expert who can interpret the logs. Please read Combofix's Disclaimer.

That's the decision by the creator and we will abide by that decision.

To add to the warning above:

ComboFix is an extremely powerful tool which should only be used when instructed to do so by someone who has been properly trained. ComboFix is intended by its creator to be "used under the guidance and supervision of an expert." It is NOT for private use. Please read Combofix's Disclaimer. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again.

Running ComboFix by yourself is like performing open heart surgery on yourself--the scalpel and other surgical tools that is ComboFix is meant to be wielded by a highly trained surgeon only in emergencies or dire circumstances. When the surgeon is thru s/he leaves the room. So combofix should be removed from a system once it has accomplished its job, unlike an AV that is there to protect you from future infections.

. . . CF does make some alterations to your system if you run it. Even if you had no malware removed and run the uninstall command, some things may be different now on your system. I can tell you that one thing is that all your restore points will be flushed out and a new one created. There is a good reason to do that when you have a severe infection--but if you aren't infected you might need those restore points.

Read and abide by the disclaimer people. It's there for a reason. Stick to running and protecting yourself with a good AV and firewall and an anti-malware scanner or two. If you feel you need a second opinion, try running online scans. If you feel you might need surgery, come here to BC and ask for help--that is what we're here for.

As for your question: the following quote explains why you are getting that message:

Certain embedded files that are part of legitimate programs or specialized fix tools such as Combofix may at times be detected by some anti-virus and anti-malware scanners as a "Risk Tool", "Hacking Tool", "Potentially Unwanted Program", or even "Malware" (virus/trojan) when that is not the case. This occurs for a variety of reasons to include the tool's compiler, the files it uses, registry fixes and malware strings it contains.

Such programs have legitimate uses in contexts where an authorized user or administrator has knowingly installed it. When flagged by an anti-virus or security scanner, it's because the program includes some features or additional files that can potentially be used for malicious purposes. These detections do not necessarily mean the file is malware or a bad program. It means it has the potential for being misused by others. Anti-virus scanners cannot distinguish between "good" and "malicious" use of such programs, therefore they may alert you or even automatically remove them. In these cases the detection is a "False Positive".

The first rule of ComboFix is: you do not talk about ComboFix.

...wait a minute, maybe I'm thinking of something else :thumbsup:.
