In this case, you should remove it and run a full system scan with a reliable antivirus software.

vnc server is a remote acces program. Server is the host. Viewer has remtoe acces to you PC. Access can be protected with a password.
If you see this file on your system, and YOU didn't install it, (You'd know.), You are in TROUBLE! Someone who had access to your system likely set it up to allow them FULL ACCESS to your computer, even the ability to watch you work without your knowledge! Serious potential for misuse!!! PD
I don't find it dangerous. Very useful remote desktop program Acillatem (further information)
Like PD said, this is dangerous if it shouldn't be on your computer. Otherwise it's a very useful tool. I guess it might come under 'advanced use' for this reason. FlameBoy

vnc is hacked and some virus use it to install msconfig2 on your system... only use vnc inside your home network or on vpn/hamachi networks... just be sure your firewall/router blocks incomming ports from ip adresses from the internet... vpn/hamachi vnc control still works because data is transported trough a tunnel...

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 executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
