opvapp is from Hewlett-Packard's SimplePass program and runs in the background. Dunno what it does but it takes nil CPU power and no suspicious connections (only connections it made were to the HP servers)
It's go to do with HP Simplepass so it is not even dangerous. HP would be sewed if opvapp.exe was dangerous or malicious
I was having a problem with BrowseFox. The McAfee anti-virus software couldn't get rid of it and, while on the internet, McAfee alerts were happening about 3 times per minute. One of the online solutions that I found for tracing down this particularly stubborn bit of malware said that I should look in the task manager (Windows 8.1) to see what looked out of place. I opened the task manager and when I tried to scroll down to look at the processes to see what might look out of place, it was difficult to scroll down. The scroll kept resetting itself to the top of the queue. I persisted and found opvapp in the third page down. I looked up opvapp.exe and came to this site. The site told me where to find oppvapp.exe. Rather than look in c:\Program Files\Softex\OmniPass\ , I searched my hard drive for it and found it at c:\Program Files\Hewlett-Packard\Simple Pass rather than the location specified on this site. That is when alarm bells went off in my head. The first thing I did was go to c:\Program Files\Hewlett-Packard\Simple Pass to verify that it was there. Then I went to the task manager, clicked on opvapp.exe and ended the process. Then I returned to c:\Program Files\Hewlett-Packard\Simple Pass and deleted opvapp.exe, then went to the recycle bin and emptied it. I restarted the computer. That was almost an hour ago. I have had not McAfee pop-ups alerting me to BrowseFox malware. I am pretty certain that was the source of the malware.

This is part of a HP laptop program, located under the SimplePass folder in the HewlettPackard program file
Ok so I do some pretty hard gaming on my laptop. For some odd reason, whenever I end the opvapp task in task manager, my games either don't startup, or say that they are missing key components. I really don't understand why though. Because I'll close a bunch of other tasks leaving opvapp, and my games will work fine. But when I close opvapp, my games won't even startup let alone crash.
It is normally needed as it is the system program. Most viruses try to disguise themselves as opvapp.exe so it is very hard to be found.

Best practices for resolving opvapp issues

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