My lad, Virustotal has one hit out of 71. You're good.
If Virustotal gives you less than five hits, it's almost certainly not a virus. That's the whole reason the site exists, because some virus scanners are WAY overtuned and hit on everything.
Yeah, it seems to just use tools that malware happens to abuse. Grindsoft isn't a specific detection, it's a heuristic one, which shows just how much of a false positive it is.
