100% CPU HOG while on the net!
  Cliff  
It occasionally hogs 45% of my cpu, but when it uses this cpu %age, it is doing a complete scan, when scan is over, cpu resorts back to idle state

To restrict excessive CPU usage with a multiple CPU machine use Process Explore to Set Affinity to less than half the CPUs available. For best results do this when the computer starts before vsmon.exe uses too much of your CPU.

It is part of Zonealarm Security. It is not dangerous unless you don't use Zonealarm in which case it is dangerous malware and should be quarantined or deleted immediately. Eats up a large amounts of memory whenever using torrent engines or prolonged internet usage. To resolve just shut down ZA and restart it. Very annoying when one core is being completely used by its process and your computer turns into a slug and internet speed is at a crawl :/ Hopefully the bug is resolved in future releases of ZA. BTW I still love ZA and recommend it to everyone I meet and all my customers because it offers the best protection in the biz.

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.

Best practices for resolving vsmon issues

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