This is installed by "Oxford Advanced Genie" which needs input from IE (or MS-WORD) to offer definittions of words that the mouse hovers over
  Tony C  
It's a plugin for some dictionaries such as "Cambridge Advanced Learner's Dict". It provides "Quicking Find" when you want to find a word much faster. Contact me at: samuelchuckwiles"@"

Came from "Oxford Advanced Genie" dictionary
I have no idea how it came onto a laptop, but because of that add-on in IE, the user couldn't go to the website of Adobe, Facebook,... The user could visit those websites again when the add-on got disabled.

Getting some error related to iehelp.dll while installing Cambridge Advanced Learner Dictionary. Plz help
When I install Oxford Advanced Learner's Dict Genie, my BitDefender seized this file and the installation is terminated. I think that I should disable my Antivirus program for a time, then when I finish my installation, I will remove iehelp.dll later (because I trust my antivirus program).
AVG removed it
  E Pedersen   (further information)
I think it is from one of Oxford or Cambdrige dictionaries becuse after I installed this 2 it appears on my IE10 but I disabaled it for security

Best practices for resolving IEHelp issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active IEHelp process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the IEHelp.dll on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. 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.
