The IPS has signatures matching patterns for various viruses and malicious codes.

IPS analyzes the packet/stream and if it matches any of the signatures that are enabled, it will take predefined actions like block/ alert, etc.

You can get more details on the Cisco ips signatures here.

You are right. IPS is not an anti virus appliance, ie: it will not be able to clean the host which is infected by virus, however, it can help to prevent the spread of network virus. IPS can detect that there is anomaly of the traffic from normal traffic pattern, and will be able to detect and prevent the outbreak of the virus.

Hope that answers your question.
