That's probably "HP Virus Throttle" for RHEL4. It's effectively a network connection rate limiter. The idea is that it slows down the spread of both known & unknown viruses by slowing down outgoing connections to "unfamiliar" destinations.

This is *NOT* a true anti-virus product, just a "damage limiter". If your systems are running in a network that has a high probability to get infected by malware, it might be somewhat useful... but to me, that feels like giving up instead of protecting your systems properly.

I think vtd stands for "Intel Virtualization Technology for Directed I/O"

On the other hand, here is what vtd means.

To stop or ignore the message:
# chkconfig hp-vt off
# service hp-vt stop

Hope this info helps you.
