It's annoying and produces an error message on startup. I've clicked debug and I've clicked close neither have made a difference to my computer or the error.

In my case it is in \Program files\epson software\event manager. Size is 953 KB (976,320 bytes). Datre 12\3\2009. I got a Windows Firewall message at the end of bootup: "Windows Firewall has blocked this program from accepting inncoming netwrok connections. If you unblock this program, it will be unblocked on all private networks that you connect to. Etc." Because of date and llocation I decided it was OK but this does contradict the idea that it does not use the Network so this made me cautious. I am cleaning up a friend's computer and set my network as "Work" in Vista Home edition
I don't know why I may need it. The Firewall blocked it and I wonder if that is OK to keep it blocked. Then I wanted to know if I need it at all or should unistall... or if I should create a permission for this application
Not much, first time it popped up as using too much room.
This is the application that allows a user to scan documents/images directly to their PC via the buttons on an Epson All-In-One printer.

It was taking up 40+% CPU usage on my computer. It did not seem to be essential in any way and possibly malware. I deleted it completely and my computer works faster now that it's gone.
This thing is using 25% of the CPU. Need to turn it off
Made internet connection slower and then prevented internet access entirely. Removed and internet is ok now. But printer still doesn't work. Not malware, specifically checked with Norton. I hate this thing. Epson support is unintelligible, not addressing the issue, asking what ink I used. The problem is not the ink. And I don't need it to scan from remote locations. It takes too much room, slows other processes.
Part of the Epson suite installed when using Epson printer software. Causes games to minimize from fullscreen. Used MSCONFIG to prevent this and status monitor from starting on boot.

Best practices for resolving EEventManager issues

A clean and tidy computer is the key requirement for avoiding problems with EEventManager. 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 EEventManager.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.
