If you would have bothered to look at the properties of this file you would have seen that it is a "truevector device driver" from the company zonelabs inc.
This is the company that makes zonealarm and truevector is part of the firewall engine. So you might want to uninstall zonealarm and see if the problems go away or maybe try a newer version of the firewall (current version: 2.6.231)
