People notice an ezSP_Px.exe file running in the task manager and when it is checked it appears to be not related to any WIndows processes. There is a high risk for a virus, spyware, trojan, or worm infection since the lie is not an essential OS file, generally, so removing the piece is recommended.
ezSP_Px.exe is an application and it is from the company Easy Systems Japan Ltd. You should scan the machine with a security or antivirus tool to see if the system shows any signs of infection. This application is installed by the Easy Systems Drag’n Drop CD & DVD writing software, which is found on most Japanese computers, so not every machine needs it.
If you want to delete this application because of the all of a sudden appearing then do so, but make sure to check the purpose and security before that. If the file is located in the C:\Windows\System32 folder and the file size on Windows 10/8/7/XP is 40,960 bytes it should be safe and not malicious.
