Q-27: My antivirus / antispyware program reports WinPcap as a virus /
trojan/ spyware! Are you hackers trying to infect my computer?

A: WinPcap is not a virus. WinPcap is an industry standard library used
by many tools, several of which commercial, and developed by a
respected team of people. However, since it's free and since it's an
easy and powerful way to receive and transmit low-level network
traffic, it seems that some virus writers used it too. As a result, at
least once a month we have somebody complaining its antivirus program
tells him that WinPcap is a virus. Your antivirus program should detect
the virus itself, not the libraries used by it. It's like saying the MS
Winsock is a virus because some trojans use sockets to send or receive
data on the network.
So, please contact your antivirus company and tell them to fix the
problem.
