PUA-P2P -- Snort has detected a Potentially Unwanted Application (PUA). This Is a program which installs adware or toolbars, collects information, runs unwanted processes that consume computing resources, or has otherwise unclear objectives. These are usually additional programs bundled with legitimate programs. Some users consider the benefit of the main application to outweigh the risks of the PUA; you are paying for a free product by contributing with advertising or data. These alerts are often assigned a lower risk, as they are not directly malicious or as fast-spreading as worms or trojans. This alert concerns Peer-to-peer (P2P) transfers in open and unregulated systems (such as Napster, Filezilla, etc.), where files and data may be shared freely. Corporate policy usually discourages this, as users could circumvent access permissions, share sensitive data, or corrupt and distribute malicious files.
