External information from Paul Collins:
There are different files with the same name:

  • "TrueVector" must run at start up. Even if you don't have ZoneAlarm or ZoneAlarm Pro run at start-up you do need this
  • "Zone Alarm" definitely not required. Added by the RBOT.BO WORM! If this was the ZoneAlarm firewall the name column would be TrueVector

Important: Some malware camouflages itself as vsmon.exe, particularly when located in the c:\windows or c:\windows\system32 folder. Therefore, you should check the vsmon.exe process on your PC to see if it is a threat. We recommend Security Task Manager for verifying your computer's security.

I would confirm with sevrin, same cpu usage on mine, especially when i play online

If you're using Zone Alarm, it's a core element. Start-up CPU use depends on the size and amount of ZA and system updates.

VSMON, for me, tends to eat CPU when I use VUZE client, I'm not sure if that's to be expected or not. It also gets into a fail loop if I use the 'TOR Project' software. Otherwise it seems to play well with my machine

vsmon.exe is causing serious problems with my computer. If I kill the process using control alt delete then sure vsmon comes back but it stops causing freeze-up's and other problems.

Takes at least 33% of CPU. Need further investigation.
  Sevrin  
As of December 2011 this hogging of CPU is most certainly NOT fixed. I cannot watch streamed video, downloads which should take around 2 minutes are taking 45+. After 10 years using ZA I shall be looking for an alternative.

It's a buggy piece of crap that on the newest software update late Nov 2011 caused my system to crawl again like last time I decided zone alarm wasn't worth it. Time to find another firewall.

Like thomas said there is a worm masquerading as this file, however, playing back huge video files such as 1080 dpi on a older machine can cause problems, since vsmon has to look at everything BEFORE its actually executed. Also another reason could be that you are already infected and vsmon is attempting to fight off this infection. I've had this problem for around 4 or 5 years... it usually goes away after about 10 minutes of allowing it to run. Post related to this problem on za site forum. http://forums.zonealarm.com/showthread.php?t=77067 Also the file should NEVER ask for outbound communication. The poster never said anything about inbound(non-server comm.) but if something asks to accept connections(which is TOTALLY different from just receiving info regular incoming data) coming from the internet. The safest thing to do is to block it and see if the Internet or application works normally without it. Also please don't rely on others to set your firewall setting for you. It may take a while to critique your firewall settings, but you can't be sure the millions of people who use this know anything about computer security. Obviously, from reading a lot of these postings... barely anyone knows anything. more info related to this worm below. However you should already be protected since the patch came out in 2004. ***one last note... blocking this from running will disable your Internet connection***
