I tried to download ComboFix from a forum thread that pointed to http://download.bleepingcomputer.com/sUBs/ComboFix.exe. My McAfee throw a flag on an Artemis trojan detected. Is this normal?

Please note the message text in blue at the top of the Am I infected? What do I do? forum.

No one should be using ComboFix unless specifically instructed to do so by a Malware Removal Expert who can interpret the logs. It is a powerful tool intended by its creator to be "used under the guidance and supervision of an expert", NOT for general public or personal use. Combofix was never meant to be used as a general purpose malware scanner like SuperAntispyware or Malwarebytes' Anti-Malware. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again. Please read Combofix's Disclaimer. That's the decision by the creator and we will abide by that decision.

With that said, Combofix is not malware. However, 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, malware strings it contains and the type of security engine that was used during the scan.

Such programs have legitimate uses in contexts where a Malware Removal Expert asked you to use the tool or when an authorized user/administrator has knowingly installed it. When flagged by an anti-virus or security scanner, it's because the program includes features, behavior or files that appear suspicious or which 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 or that it was simply detected as suspicious due to the security program's heuristic analysis engine which provides the ability to detect possible new variants of malware. 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".

Thanks for the reply QuietMan. Sorry I didn't say so sooner, but I lost my logon and had to recreate and sometimes my life runs slower than my computer. I will open a new topic on why I was told to get ComboFix in the first place. Thanks again. Later!

No need to open a new topic. You can continue here. If necessary, we can move this topic to a more appropriate forum.
