its a part of ca trust security center not dangerous at all
It is apparently a part of Computer Associates EZ Antivirus - part of Zone Alarm's Internet Security Suite. Even though I chose not to install the Anti Virus, VET Message installed and is running on its own. Also see CAISafe - another component of EZ Antivirus which also installed on its own and is now running on my system. I am going to disable them both and see if I really dont need them as I am already running AV software (that i paid for).
Is a part of the EZ Antivirus software
This is part of CA EZ Trust Antivirus software
ca epired on my laptop and ichoose not to renew it but the notice to renew constantly pops up on my screen and nothing I have tried will get rid of it so I call it a virus
I never installed any anti-virus software or have even heard of CA AV, so I don't know where this came from. It also consistently opened windows alerting me to a path that doesn't exist being a virus. I may have gotten a Trojan, but until I can prove that, I'm going to classify this process as a virus.

Best practices for resolving vetmsg issues

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