It is a part of blackice, if you dont have blackice installed then it is malware
Along with other BlackIce/Proventia pieces, this program continually scans every file, every executable, everything all the time. On a dual Xeon engineering workstation, it continually slows this powerhous down so that I get frustrated every day. It's installed by my company so I can not disable it. More annoying than helpful in my opinion.

As noted, it's part of Proventia Desktop Protction and as such is an integral part of that tool. If you don't want the protection then why did you buy the software?

Best practices for resolving RapApp issues

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