I am using ZoneAlarm Antivirus. Several times I have received a message alert that the Synaptics Touchpad Enhancement is trying to control something. That message freezes everything and I can't even get the mouse to move. I have had to buy an external USB mouse so I can turn the machine off. When I clicked on more info, the ZA website said this could be malicious. What do I do?

Operating System:Windows Vista Home Premium
Software Version:7.1 (Vista)
Product Name:ZoneAlarm Antivirus
