hogging all virtual memory on three of my family's computers. It seems to want to share internet providing duties between explorer.exe and itself, iexplorer.exe. I'm not sure why. All I know is that it slows the internet to a crawl. Dial up seems faster than DSL with iexplorer.exe. I ended the process in my virtual memory and it seemed to stop and my connection was back to normal.
This one took me awhile to figure out. First of all, the iexplorer I got was a memory hog that slowed down the internet. It immitates the good file, iexplore.exe. I found it and deleted it in the internet explorer folder. After deleting it, windows "healed" that "wound" by replacing it by itself with iexplore.exe. And since then, I haven't had any problems with it. Remember, don't delete iexplore.exe, this is a good file. Delete the malware copy/immitation iexplorer.exe, and, if it works like mine did, windows will replace the missing hole you've created with the real file.
Spyware created in C:\windows\iexplorer.exe
I had one and ended up to reformat .
I know that I have been trying to get rid of it for 2 weeks. I've been through just about every commercial malware/ad/spy scanner available. I know that it is in C:\windows and that it relies on another root file to respawn after deleting it. I know that it now has the power to Autoclose Task manager while it is running. I know that if you completely remove the good Iexplorer in program files, it cannot execute it's actions. It will complain to you that it cannot access internet explorer (lol in your face). I know that I have removed over 20 viruses from my computer using pscan.exe by Ikarus.
It also exists in folder "Programme Files/Internet Explorer" in my computer. It has been downloaded automatically and windows security system asked me whether to run it or not with a warning of is being suspecious.

I use the public library time is valuable. When it comes on, the screen turns off, and causes waste of time to start all over again. I am not authorized to do anything to correct the problem.
If Nortons says its a Virus Its a Virus!

Stopped the process and deleted it. Took a couple tries before iexplorer.exe stopped reappearing as a process. It's not internet explorer because internet explorer shouldn't be running all the time in the background.
malware caused by project neptune keylogger.. have it in my pc since i experiment this software, be careful guys.... you should know how to identify... check the signature and verification to be able to trust an application.
Microsoft Internet Explorer
CPU crazy high

Best practices for resolving iexplorer issues

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

To help you analyze the iexplorer.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
