Internet Explorer using 99% CPU

mnovaes · 09-11-2008, 08:43 AM

Hi. I'm using IE 7 in Win XP with service pack 3.

THe browser starts and works fine until I visit a particular webpage. Then everything gets real slow, and I can see in the Task Manager that iexplore is using 99% of CPU. If I close that page all comes back to normal.

The page is http://veja.abril.com.br/blogs/reinaldo, it is a simple blog and this problem only started yesterday.

Here is a HijackThis log, done in normal mode:

After posting the above I noticed the same problem on other webpages (they don't seem to have anything in common), so nothing special about the one I mentioned. .

Kyrianne · 10-01-2008, 04:30 PM

Try setting the 'iexplore.exe' process to 'low' or 'below normal.' That should make the CPU usage drop drastically, though it may affect your browsing slightly.

How to do this: Ctrl + Alt + Delete, then when the Task Manager pops up, click the 'Processes' tab near the top. Find the process 'iexplore.exe' and right click -> set priority -> below normal or low.

Hope this helps!
