installed with netgear wireless network drivers
During installing the Planex's 54Mbps PCMCIA WLAN card's utility program under Windows XP, the installation program will copy this file from "c:\windows\"
This file can often end up propogating it's miniport service to other network adapters and preventing uninstallation of ghost hardware devices in the future. This causes system instability. I've seen this one 3 unrelated systems (2 2k, 1 XP).
Needed for Vodafone datacards and for some WiFi miniports
Associated with Motorola WU830G Wi-Fi Adapter - probably. Resides in x:\windows\system32\drivers\odysseyim3.sys .
An addition, have 2 inf files (mine are OEM0.inf and OEM1.inf). The installation in OEM1.inf (miniport) is described as: Characteristics = 0x29 ;NCF_NOT_USER_REMOVABLE NCF_VIRTUAL NCF_HIDDEN There is no uninstall possibility allowed. The driver is responsible for authentication. In this case uninstall is not recommended (and it's blocked!).

Best practices for resolving odysseyIM3 issues

A clean and tidy computer is the key requirement for avoiding problems with odysseyIM3. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the odysseyIM3.sys process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
