Hi True Indian and Steven Winderlich,
You have to give room to avast! shields detection with a much more prominent role to play since the 2014 version.
I have found that the avast! Web Shield for instance now also flags mal-defacements.
So when the avast shields were being "phased in" the detection patterns for avast may differ.
So there could be room for a discrepancy as I do not know if VT results also will include the avast! shields detection results?
