This is just "Free Multi Clipboard". This program replace your clipboard and add more options
So far the only way I have been able to remove this file is by booting in safe mode and deleting it. However, after I updated my cox cable security suite software it came back. I called cox and they said this file is not theirs. However, as usual they blamed everything from Ad Aware to Spy Bot, to XoftSpy (other software I have on my system) for the cox suite not working to catch these files.
Found by a squared as possible malware
It's part of DesaWare's spyworks suite.

Best practices for resolving dwspy32 issues

A clean and tidy computer is the key requirement for avoiding problems with dwspy32. 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.
