[What's this PUP.GamePlayLab thing? Is it dangerous?]

Hi,

Recently I found a strange ad program on firefox where it would highlight random words and if I mouse over it, it would give me an ad somewhat relating to that word. Anyways, I found the addon called vid-saver and removed it. Since I know I never installed it, I scanned my computer with MBAM and my Kaspersky Internet Security. Kasperksy came up clean but MBAM had some registry keys and PUP's linked to the vid-saver thing. Do you guys know if this is potentially dangerous or should I just delete it and act like nothing ever happened? I put the log down below.
