What is navapsvc.exe?
This is the Norton AntiVirus Auto-Protect Service. It is installed as a part of Symantec Norton AntiVirus. Its purpose is to reside in memory and ensure that viruses do not get installed on your system.

This process is not essential to the operation of the system; however, it should not be removed unless it is causing problems. Removing or disabling this program will at minimum disable your Norton AntiVirus auto-protect and possibly cause more serious problems, such as a complete loss of virus protection or an inability to boot.

Dangers of navapsvc
As this is a legitimate executable that is installed on most systems with Norton AntiVirus or Norton Internet Security, 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 as this process but be stored somewhere other than in %ProgramFiles%\Norton AntiVirus. 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 navapsvc.exe 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 a Symantec Norton product installed, the presence of this executable is a likely sign of a virus infection.

Common problems
  • "Windows cannot find %ProgramFiles%\Norton AntiVirus\navapsvc.exe"
    • It is possible that a virus disabled Norton AntiVirus. You will need to reinstall it.
  • This process uses 100% of the CPU
    • There are many possible causes for this. It is possible that you have a conflict with another anti-virus program. If you have any other anti-virus software installed, uninstall it.
    • There may be a conflict with another piece of security software. Try uninstalling any anti-spyware and firewall software you have installed.
    • If you are running any distributed computing software (such as SETI@home or Folding@home), try disabling it.
    • If the problem persists, reinstall Norton AntiVirus.
