IEXPLORE.EXE is what the Internet Explorer process is called in the task manager. But sometimes viruses pretend to be Internet Explorer. How to find out which is which? Easy - just check the path to Internet Explorer. Usually IEXPLORE.EXE is located in a subfolder of Program Files (generally Program Files-Internet Explorer). If you find it in a Windows subfolder, then the security

rating is 82% dangerous. Close Internet Explorer and check out the Task Manager. If you still see IEXPLORE.EXE as an active process, then it's probably a virus or another unwanted program. Try running your anti-virus program in Safe Mode (to boot in Safe Mode, tap F8 repeatedly on startup) to get rid of it.

Sometimes the IEXPLORE.EXE process takes up about 80% of CPU usage and Internet Explorer becomes really slow. First of all, check which version of Internet Explorer you have installed. Update it if it's an older version. Hopefully, the problem will go away after the update.

A good thing to do is check all ActiveX controls, as some of them might be faulty.  First disable all ActiveX controls and see how it goes. If Internet Explorer speeds up and the high CPU usage issue is gone, start re-enabling ActiveX controls one by one to find out which of them is the culprit. Delete it when you find it. This may cause problems with some websites that require that particular ActiveX control, but that is highly unlikely and on the whole your computer performance will improve.

How to Kill All IEXPLORE.EXE Processes at Once (Vista)

Sometimes when you take a look at the Task Manager, you see about ten IEXPLORE.EXE processes running at the same time. And let's say you need to forcefully terminate all these processes, but you don't want to waste your time clicking End Task for each of them.

Otherwise you will need to use administrator mode command prompt.

1. Click on the Start button, then go to Programs - Accessories - Command prompt

2. Use the following command to kill all Internet Explorer processes at once:
