There are several blacklist reporting sites to help you discover if you're a zombie.
Through a virus or worm, a criminal takes over your PC, which behaves normally until it receives instructions over the Internet to mass mail spam, take down a company's network as part of a DDoS attack or log your keystrokes to gain access to your bank account. When it's done, your system reverts to acting like a normal PC.
You can't easily tell if your PC has been zombified. The usual malware warning signs -- computer slowdowns, odd behavior -- apply to zombies, though they could easily be signs of lesser problems. Watch your firewall software for strange outgoing traffic.
