I clicked the thing at the bottom to go to the celtics talk forum from the around the nba forum and a file called dynamic_ytrack_sync automatically downloaded to my computer. Never happened before and I couldn't get it to happen again by doing the same thing again. No other windows or tabs were open so I think it must have came from here. Not sure if the owners here know about this or not. Just thought I'd give everyone a heads up as it looks to be malware.
