What is vsmon.exe?
Vsmon.exe is ZoneAlarm True Vector Monitor. It is an essential component of the third-party ZoneAlarm firewall software.

This is an nonessential process. If you wish to disable it, you should uninstall ZoneAlarm. If you need to disable it temporarily, you should exit ZoneAlarm properly. Killing the process may leave you without a network connection until your next reboot occurs.

Dangers of vsmon
As this is a relatively common process in that it is part of a popular third-party firewall software, it is common for virus writers and spyware vendors to disguise their malware as the genuine one.

Some malicious files may have the same name but be stored somewhere other than in %SystemRoot%\System32\zonelabs. Other malware may use a name that appears similar to it but with slight differences in spelling or with appended digits. The following malware is known to disguise itself as vsmon.exe:
  • W32/Rbot-FB (%SystemRoot%\System32)
    • This is a backdoor Trojan that can spread over network shares. It allows a remote attacker to take full control over an infected system.
There is typically only one instance of this process running at a given time on a system. The presence of multiple instances may be an indicator of a malware infection. Furthermore, if you do not have the ZoneAlarm firewall installed, an instance of this process is almost certainly an indication of a piece of malware on your system.

Common problems
  • This process is using 100% CPU time
    • If you have anti-virus software installed, be sure that MailSafe is disabled. MailSafe conflicts with the mail scanning features of most anti-virus programs.
  • This process uses excessive memory
    • If you have anti-virus software installed, be sure that MailSafe is disabled. If this does not resolve the problem, try turning off the ZoneAlarm virus engine. There are known memory leaks in it.
