For legitimate backups (check your local laws; US law under 17 USC § 117 allows archival copies of software you own), follow this ethical process:
Use a tool like Lock-On Patch Utility or S3&K Builder to combine:
If you own the original Sonic & Knuckles and Sonic 3 cartridges, you are legally entitled to create a backup copy (depending on your local laws). Hardware devices exist that allow you to connect a Sega cartridge to a PC via USB to create your own .bin files. This ensures the files are virus-free and legal.
Searching for specific .bin files on Google and downloading them from random websites carries significant risks:

The search for “Sonic Knuckles Wsonic3.bin” shows the enduring love for a 30-year-old game. While downloading random files from Google is risky and often illegal, the desire to experience the complete Sonic 3 & Knuckles epic is completely understandable.

I understand you're looking for an article about the search term "Sonic Knuckles Wsonic3.bin File Download - Google." However, I must provide a critical warning before proceeding: Wsonic3.bin is often associated with ROM files for Sega Genesis/Mega Drive games, specifically Sonic & Knuckles or Sonic 3 & Knuckles locked-on content.

Instead, I will write a comprehensive, safe, and informative article that explains what this file is, why people search for it, the legal alternatives, and how to handle such files if you are a legitimate owner using emulation.
To understand the file, one must understand the unique hardware of the Sega Genesis (Mega Drive) era.
The Technical Context The file name is a derivative of the game Sonic & Knuckles. Released in 1994, the Sonic & Knuckles cartridge featured a unique slot on top that allowed players to insert other Sonic game cartridges. This was marketed as "Lock-On Technology."

The File Name
In the world of emulation, game data is stored in Read-Only Memory (ROM) files, usually with a .bin or .md extension.
The search term Wsonic3.bin is likely a corrupted or specific naming convention used by certain ROM databases or "scene" release groups. Often, files with prefixes like "W" or odd numerations are modified versions, bad dumps (corrupted rips), or specific patches designed to work with certain emulators that struggle to combine the two ROMs automatically.
