I have just found WDBackupEngine running on my PC and writing to disk, even though I have no WD drives attached. I do have a WD external HD, but the only WD software I want is the password protection for that drive. Where does WDBackupEngine store its backup? I don't want copies of sensitive data files witten in locations I don't know about.

Best practices for resolving WDBackupEngine issues

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