meanwhile 27 other antivirus companies caught it…weird :
I would test the links in the comments section to see if this infected by i dont have a virtual machine right now
came across similar term when i was submitting a possible hack tool

as you can see the community is undecided on this one almost 600 votes, the most ive seen on any submission 
well… the first VT link you posted is from feb 2013 so 10 months old
the second i would say is a False Positive. First submission 2007-06-22 15:46:06 UTC ( 6 years, 5 months ago )
Hacktool is NOT malware.This is something most people confuse themselves.
Even testers do.As soon as you see most AV’s calling it hacktool unless it is really bad avast will not add detection as far as I have tested.
