Still no help? Is there any other place I can contact Avast for assistance?

Tonight my computer started to mess up again on the Yahoo page I saw it was trying to load an ad from vid-io.springserve.com. Not sure what that is, but I clicked to close the Yahoo tab, but it still bogged down my computer for a good 2 minutes before it finally closed the tab and came back to running normal.

Someone PLEASE help me with this problem.
