I keep getting a message along the lines of “Internet Explorer has encountered a problem and needs to shut down.” It then restarts and returns to the home page. This can happen at different frequencies.
Troubleshooting Internet Explorer Has Encountered an Error: Scanning for Malware
With this type of problem, one of the first strategies that I suggest is to run a virus and spyware scan. Quite often spyware and viruses infect a computer and can lead to problems such as Internet Explorer cannot display the page. The best strategy here is to run an anti-virus/anti-spyware application to remove the problem if it exists. Once this occurs, Internet Explorer usually goes back to its normal working order. If you have such an application, check to see if any updates exist and run it now. If you don’t have such an application, you can try Anti-VirusPLUS, which is a reliable anti-virus/anti-spyware program.
Troubleshooting Internet Explorer Has Encountered an Error: Updates
It is possible that you need to obtain the latest update for Internet Explorer. If you haven’t updated in a while, this becomes even more possible. The latest version is currently IE8. If you already have this version, use the next set of directions to repair it. If you don’t have this version, try uploading it now and see if that helps any.
Troubleshooting Internet Explorer Has Encountered an Error: Repair IE
Quite often, computer users can resolve Internet Explorer errors simply by resetting it. Take these steps to repair your Internet Explorer:
1) Open your Internet Explorer application.
2) Immediately select the option for “Tools.”
3) Select “Internet Options.”
4) Select the section for “Restore Advanced Settings.”
5) Select “Reset.” If you are lucky, this strategy worked.
Troubleshooting Internet Explorer Has Encountered an Error: IE Reporting Tool
Typically a small dialog box appears that offers you the chance to report the IE error. Many people don’t realize the value of this option. If you select this option to “Send Error Report,” the “Internet Explorer Error Reporting Tool” will first check to see if the problem has been resolved. If it has been resolved, this tool will direct you to the appropriate webpage to fix the problem. Typically, this involves downloading a patch or workaround for that particular problem.
Troubleshooting Internet Explorer Has Encountered an Error: “System Restore”
Another workaround that might work for you is to complete a “System Restore” to place your computer back to a time when IE was working properly. This strategy might or might not work for you.
Troubleshooting Internet Explorer Has Encountered an Error: Add-ons
This strategy is usually one that works if you have recently included any add-ons for your Internet Explorer browser. Try running it without the add-ons and see if the problem continues. Go to Start> Programs> Accessories > System Tools> Internet Explorer with No Add-ons. If it works properly, then you can experiment with each add-on one at a time until you discover which one is creating the problem for you. Do this by going into the regular Internet Explorer and clicking Tools > Manage Add-ons. You could also try uninstalling the latest add-on to see if that makes a difference for you.

I’m guessing you are also running Windows Vista? Internet Explorer errors such as this one have been reported. No matter what operating system or version of Internet Explorer you are running, this is annoying. My IE 7 browser has done the same on occasion but not continuously.
