It's an Immunet 3.0 Agent
Caused my other computer to seize up and now it is working on my current computer. I think it was installed with Roxio Creator DVD Edition version 7. Since I can't figure out how to stop it from starting on its own I will attempt to rename the agent.exe to bad_agent.exe and see if that helps. Agent.exe is a problem and it has done this to me twice. I am not sure if it was installed with Roxio or Dragon Naturally speaking, I will need to research this.

Why have a virus resident in your pc where it can be detected? Agent exe runs all the time, regenerates upon a process kill, does nothing if not connected to internet. After internet connection, pulls in remotely resident virus as svchost.exe and that sucks up 100% of CPU, is not detected by usual antivirus or anti malware. Nasty. Watch for it to be benign when not connected to internet.

Several instances are found in Program Files (X86)EasEUS ToDo back-up and have been there since I installed this programme several years ago. They do no harm as far as I know.
Installshield, Macrovision. Was maxing out my physical memory, crashing whatever was running. Searched in Windows Explorer for ISUSPM as recommended above; found it was trying to update a FedEx printing program I had already uninstalled (finished deleting/shredding remaining components of FedEx with SlimCleaner) and a Roxio program I don't use (changed to manual update).

Best practices for resolving agent issues

A clean and tidy computer is the key requirement for avoiding problems with agent. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the agent.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
