Hi & :welcome: to Bleeping Computer Forums!

It's a false positive.

Note:

 

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 Emsisoft Anti-Malware or Malwarebytes Anti-Malware which scan individual drives or different folders on a computer for malware...nor was it designed to be a remote support toolUsing this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again. When issues arise due to complex malware infections, possible false detections, problems running ComboFix or with other security tools causing conflicts, experts are usually aware of them and can advise what should or should not be done while providing individual assistance. Those attempting to use ComboFix on their own do not have such information and are at risk when running the tool in an unsupervised environment. Please read Combofix's Disclaimer.

Expanding on deeprybka's comments.

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 suspicious, a Risk Tool, Hacking Tool, Potentially Unwanted Program, a possible threat 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, whether files are compressed or packed, what behavior (routines, scripts, etc) it performs, any registry strings it may contain and the type of security engine that was used during the scan. Other legitimate files which may be obfuscated, encrypted or password protected in order to conceal itself so they do not allow access for scanning but often trigger alerts by anti-virus software.

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. Compressed and packed files in particular are often flagged as suspicious by security software because they have difficulty reading what is inside them. These detections do not necessarily mean the file is malicious or a bad program. It means it has the potential for being misused by others or that it was simply detected as suspicious or a threat 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" and can be ignored. Either have your anti-virus ignore the detection or temporarily disable it until you download and run the tool.

Artemis technology is the "Active Protection" component of McAfee's Security Center which uses a combination of signature and behavior analysis to check with McAfee servers in real-time to identify possible new malware threats. This is accomplished by adding heuristics to the virus database. McAfee then uses this heuristic detection to analyze the cataloged behaviors and assess the likelihood of possible new variants of malware before the vendor can get samples and update the program's definitions for detection. This process is similar to Symantec's Bloodhound Technology. Artemis is not the name of an actual virus, but an alert displayed by McAfee when it thinks it may have found a new virus. Artemis is included in the detection name for any file that is quarantined or blocked by McAfee's Global Threat Intelligence (GTI) technology for enhanced detection of unknown threats based on the file's behavior. Thus, Artemis detections may or may not be malicious.

The problem is really with the anti-virus vendors who keep targeting these embedded files and NOT with ComboFix. We can inform the developer but he has encountered this issue many times before and in most cases there isn't much he can do about it. Once the detection is reported to the anti-virus vendor, they are usually quick to fix it by releasing an updated definition database.
