Is Mdm.exe a virus?

Although the true Mdm.exe file is a safe file, many spyware and virus programs disguise themselves by adopting similar file names. Some such malware programs that disguise themselves as mdm.exe are listed below, along with the corresponding file location:

If your PC is infected with any malicious files, you should immediately scan your system using efficient AntiVirus and AntiSpyware tools. Furthermore, these malicious programs embed harmful entries or keys within the system registry, so we recommend you use a robust registry cleaning tool, such as PC Health Boost to scan and weed out malicious entries from the registry.
