Exactly what "TB" AND "ssuutb" said. It's a Win sys service or process or whatever the h-e-double toothpick *.exe files that come with Win OS'es do. dvpapi coordinates the windows "system security" center pphhh with whatever security suite (SMP, Norton) you have geezed from your buddy or ripped off. It's dangerous if you find it missing all of a sudden!
DVPAPI component is also used by IOLO antivirus program. Iolo antivirus program will not funcion without it
its a file that gets installed with certain antivirus, it doesnt come with Windows. also to those who think it may be malware check the spelling closely, along with caps,spaces, file extension name etc
Its essential for programs like iolo anti virus to run properly

Best practices for resolving dvpapi issues

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