Computer threats can do a lot of things on your computer. They can damage files, slow your PC down, show messages you don’t really care about, create problems connecting to the network, and can take control of the whole system. Some viruses are designed to harm your computer by damaging initially functional programs, deleting important and unimportant files, and reformatting the hard drive. Most of these threats are viruses, but there’s another threat that everyone seems to know but nobody finds easy to combat—Trojan horses.
A Trojan is a form of malicious software or malware that looks legitimate but can take control of your entire computer system. It is created to damage, disrupt, steal, or inflict harmful action on your data or network.
One of the most common types of Trojan horses is Nmon.exe.

Is Nmon.exe a Virus?
No, it is not. It is a Trojan, another form of malicious software. Should Nmon.exe be removed? Not necessarily.
Here’s an indicator of whether or not you should remove Nmon.exe.
Nmon.exe is linked with OnMark 2000 Survey. If the file you have is actually related to this program, then its location path should be C:\Program Files\Viasoft\OnMark 2000 Survey\NMON.EXE. If you find your file having the same path, then it is safe to say that it is related to the program and not malicious. But if it is found in any other folder or location or simply cannot be located, then you should consider it a potentially undesirable and harmful element and you should look out for any malware traces or virus damage.
