Looks like they were FPs as I suspected, though those two VT results were from 2011-04-08 21:35:02 (UTC) and 2011-04-08 21:36:29 (UTC).
Can you rescan these two files in the avast chest, hopefully avast will no longer detect them, based on these VT results ?
If they come up clean then you can leave them.
