Hi Tech,
It is considered as a so-called risktool. That means that if you have installed it yourself it is no risk, but if it comes from third parties or with malcode it is (or could be used as) a hacktool. What more it is a heuristic find and packed with UPs - that why it is flagged by the major av solutions as "not-a-Virus.Hacktool.NirCmd".
Some av solutions to-day are strict here (those with small business anti-malware solutions), because risktools are being frowned upon by system admins and the like (especially if they haven't installed them themselves and they would be run by the user of the work computer). With a hammer one can sculpt and one could ruin alike, with a tool one could protect and one could hack.
I think a good av solution should have a special category for these tools to be used by advanced users and qualified uninstallers and create an easy way to exclude them from getting flagged as those users that knows what they are doing may authorize it,
