Description: WinVNC.exe is not essential for Windows and will often cause problems. The file WinVNC.exe is located in a subfolder of "C:\Program Files" or sometimes in a subfolder of "C:\Documents and Settings" (generally C:\Program Files\RealVNC\WinVNC\ or C:\Program Files\ORL\VNC\). Known file sizes on Windows 8/7/XP are 712,704 bytes (19% of all occurrences), 474,624 bytes and 44 more variants. http://www.file.net/process/winvnc.exe.html 
It is not a Windows core file. The application listens for or sends data on open ports to a LAN or the Internet. You can uninstall this program in the Control Panel. The program has no visible window. WinVNC.exe is able to record keyboard and mouse inputs, hide itself and monitor applications. Therefore the technical security rating is 40% dangerous; however you should also read the user reviews.
In case you experience problems using WinVNC.exe, you can uninstall the associated program (Start > Control Panel > Add/Remove programs > UltraVNC or TightVNC), look for help [1][2] from the software company Ultravnc or update [1][2] to a possibly bug-fixed version.

opensource remote control utility (possibly dangerous, if not installed by yourself)

Virtual Network Computing, a remote control application, and if you did not install this yourself then it should be removed.

See other comment. If you self haven't installed it... your pc could be remote controlled, otherwise, you problably know what this is.

This program gives you remote access to your computer. I highly doubt anyone who knows how to install a remote desktop service would wonder what it is.

remote computing, pc 2 pc desktop access - quick - can be spyware - can be dangerous if you don't know what you're doing as the world can access the computers it's installed on, if they guess the password. Block the ports with a router on local lan and it's safe.

Remote desktop control program with file transfer capabilities.

It can be dangerous if you allow it to. I use it at times to get into several other computers in my home office, mainly just movie collections from my mce 2005 in living room. Always keep yourself behind a good firewall type router, hardwire still my choice. and use a good firewall within your OS as well, check your ports and settings...then you should be able to use safely. or I should say within our current technoligy...there is always tomorrow.
   
WinVNC is used to either remote view or control a windows machine (there is also VNC software for Linux and Mac machines). In and of itself the software is not dangerous; however because it allows remote access you should either disable it or remove it if you don't use it (pity you can't do that with Windows own remote access software). Make sure that if you do use it that you set a password (the documentation on this is included with the software). I use this software on both a professional and personal basis to assist users with their machines.

Remote desktop access program.
   
It can be a part of TipCam Screen Recorder, ending the process messes up TipCam.
  HellJustFroze  
I think that is is a safe application. So, use it

Have been using RealVNC 10+ years for telecommuting

Avast hit on this filename as a possible rootkit infection. Either Avast's deep-scan repair or the removal of Dell Remote Access fixed this problem for me.

Best practices for resolving WinVNC issues

A clean and tidy computer is the key requirement for avoiding problems with WinVNC. 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 doing a repair of your installation, or in the case of Windows 8, 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 WinVNC.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. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
