Your 1st is only detected by 2 scanners, one suspicious and the other a variant of, both of which are of a higher potential for FP.
Your 2nd one is missed by every one of 43 scanners and seems like some copycat comments at the bottom of the page.
However, all this is a moot point as links to VT alone are pointless as members of the avast virus labs have said on a number of occasions, they need the samples. So it is more important to submit samples to avast.
