IE8 Shut down Abdruptly

There are sites where If we visits popup window opens and If i try to close popup or window, my computer stops working and says that Internet Explorer has encountered a problem and needs to shut down.I have IE8 installed on my computer, I have also tried to clean my registery and scanned for viruses to find out the same problem but nothing shows up. Whenever I tried to restore my laptop to a previous date, it will not allow me to do this. What else can I do?

First make sure Internet explorer has all the updates for the version you would like to use, Microsoft usually can do this through automatic updates <usually in control panel or on the start menu> This will take out any security issue Microsoft knows about.

one source of these errors is another program trying to manipulate IE. java script activeX and various other things related to internet explorer, can constantly be modified by outsiders whom you grant access to your computer. knowingly or unknowingly. Up to date Anti-virus anti-spam and anti-cookie software like Ad-Aware SE can solve most of these problems. A firewall that is up to date and allows you to see who's trying to connect or what info is leaving your computer and from what application is vita! l to keep these errors and other kinds of attacks off your computer.

If all these fail clean out cookies and cached internet files through control panel-internet options> If there are still errors then IE needs to be restored. uninstall it and reinstall from a clean file. after downloading or installing scan the d/l or directory with any and all virus programs you have to verify that that is not your source of your problems. Update as soon as possible.
