Sniffer, Spoofer (generic description).
A sniffer or a spoofer is usually a standalone program to intercept and analyse certain data. For example a sniffer can intercept and analyse network traffic and catch certain data, for example passwords. Trojans sometimes use sniffing capabilities to steal passwords and user information from infected computers.
There also exist a lot of commercial and free sniffers. They can be used to analyse network traffic for perfomance, security issues and faults.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
