Legitimate Office 2010 Process, This BHO is Unnecessary bloat.
Essential to open URL's to Word documents with custom template on Sharepoint. If this IE add-on is not enabled, Word will 'stop working' after clicking on the URL.

Best practices for resolving urlredir issues

The following programs have also been shown useful for a deeper analysis: ASecurity Task Manager examines the active urlredir process on your computer and clearly tells you what it is doing. Malwarebytes' well-known Banti-malware tool tells you if the urlredir.dll on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
