What is pccntmon.exe?
This is the Trend Micro OfficeScan Antivirus Real-Time Scan Monitor. It is the part of Trend Micro OfficeScan that is responsible for staying resident in memory to protect against viruses as they enter your system.

This process is not essential to the operation of the system; however, it should not be disabled or removed unless absolutely necessary. If you wish to disable this process, you should do so by uninstalling Trend Micro OfficeScan. If you wish to simply disable background scanning, you should change the respective setting in OfficeScan. Note that disabling this process in any way will disable your background virus protection.

Dangers of pccntmon
As this is a legitimate process that is installed on any system with Trend Micro OfficeScan, it is possible for virus writers and spyware vendors to disguise their malware as the genuine one.

Some malicious files may have the same name as this process but be stored somewhere other than in %ProgramFiles%\Trend Micro\OfficeScan Client. Other malware may use a name that appears similar to that of the legitimate one but with slight differences in spelling or with appended digits. While there are currently no known viruses, Trojans, or adware applications that disguise themselves as this process, you should look out for the presence of this file in an incorrect location or with a slightly different name.

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. If you do not have Trend Micro OfficeScan installed, the presence of this process is a strong indicator of a malware infection.

Common problems
  • "pccntmon.exe is not a valid Win32 application"
    • This often occurs when a virus tries to disable all anti-virus programs. You should reboot into safe mode to perform a virus scan and then reinstall the software.
