no one like it
Little but popped up by itself after going to an EBay dealer page
ACtually I really don't know what it does-But I do know that its not really important unless you use Team Speak overlay I guess
  K. R.   (further information)
My first experience with it was today, after starting ( then aborting) a free .xls template
It provides vulnerabilty I think
  Old Gringo  
Its the program that runs that stupid little animated paper clip guy, the office assistant, that comes down and stares at you while you are trying to type. Ah! Here he comes!

It's associated with the little paperclip guy (or other cartoon character) who pops up giving you word processing/spread sheet, etc. "advice" using Microsoft Office products. The only bad thing is that it doesn't unload itself. Shows up as a daughter process of scvhost.exe.
Confirmed. I just terminated the process (watched it via Process Explorer) and the paper clip dude, officially known as "the office assistant" popped up again as a daughter process under svchost.exe. Definitely harmless. Just doesn't terminate unless you close all Microsoft Office documents. Close office and it's offloaded.
it seems to run the microsoft agent (text to speech engine) and only appears on my pc when text to speech is run
I know little about it but don't like it. ZoneAlarm prevents it from running. I've only seen the ZoneAlarm warning when I visit a Yahoo Blog site.
Today I was in System; I clicked agentsvr.exe. Later, it showed up as the top item within Task Manager
Today was the first day I saw it, listed under my vista volume "mixer". It was listed on my task manager and I end it's process. Doing a search on my computer for Agentsvr.exe and nothing comes up. Will keep an eye on it. My Avira didn't do anything.
I have it on my PC and think it is being used by Keylogger PC Agent.

  like sky_pilot

Best practices for resolving AgentSvr issues

A clean and tidy computer is the key requirement for avoiding problems with AgentSvr. 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 repairing of your installation or, for Windows 8 and later versions, 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 AgentSvr.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.
