Does IE7 Slow Down Your PC?

Do you have the Phishing Filter enabled? When you visit some websites in Internet Explorer 7, the filter can slow down your PC by hogging the CPU.

As indicated in Microsoft Knowledge Base Article 928089 :

"This problem occurs when one or more of the following conditions are true: • The Web page contains many frames. • You browse many frames in a short time. Internet Explorer 7 evaluates the whole Web page when you browse a frame. Therefore, CPU usage may be very high."

There is an update that Microsoft has released for this issue. However, because this is not a security issue, it must be manually downloaded. It is available from http://support.microsoft.com/kb/928089 .
