A Hack Tool is typically a program, crack, or keygen used by hackers for activating/installing pirated software or to gain access to a computer without authorization.
However, some administrative tools may be detected as Risk Tool, or Hacking tool because they have the potential of being misued 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. Since these detections do not necessarily mean the file is malicious or a bad program, in some cases the detection may be a "false positive". If you installed or recognize the program, then you can ignore the detection. If not, then you need to investigate further.
Without knowing the specific file(s) name associated with possible malware threat(s) and where it was located (full file path) on the system, it's difficult to determine exactly what it was or what the scanning engine detected.
Each security vendor uses their own naming conventions to identify various types of malware so it's difficult to determine exactly what has been detected or the nature of the threat without knowing more information about the actually file(s) involved and where they are located (full file path).
These types of detections are not an infection in the typical sense...meaning they are not in the same category as infectious malware which includes viruses, worms, Trojans, rootkis and bots.
