NOThing it is a IE 8 TOOl so it is likely harmfull
  Justin s  
This IEToolbar.dll program comes from AVG anti-virus and anti-spyware company. It runs as a browser helper object in Internet Explorer. I hate the fact they used this IEToolbar.dll name when they are an anti-virus company, as this name has been used for rogue programs and therefore creates confusion. This program is considered safe, and is not virus, adware, or spyware related, but double check the location as mentioned. Visit ietoolbar.dll for complete information on this task or process.

It has something to do with AVG antivirus tool bar for IE8
OK, let me tell you something. The only reason I deleted it was because I found out it was unsafe AND, it was 45GB! GB! Huge file that killed my laptop. It had to go. It does nothing apparently but sit there. And AVG is running fine without it, I'm sure this wasn't part of AVG.

Best practices for resolving IEToolbar issues

The following programs have also been shown useful for a deeper analysis: ASecurity Task Manager examines the active IEToolbar process on your computer and clearly tells you what it is doing. Malwarebytes' well-known Banti-malware tool tells you if the IEToolbar.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 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
