IE7 phishing tool slows down PCs

Microsoft has admitted that its recently launched Internet Explorer 7 browser can slow down users’ PCs.

“The computer may respond very slowly”, said the company, “as the integrated Phishing Filter in the browser evaluates web page content”.

The anti-phishing tool was a key new feature to the browser, but Microsoft has been forced to issue an update for Windows XP and Windows Server systems loaded with the browser, to help them avoid slowing down.

Microsoft said the problem can occur when the web page viewed contains many frames or many frames are viewed “in a short time”.

The company said Internet Explorer 7 evaluates the whole web page when each frame is viewed. Therefore, said Microsoft, “CPU usage may be very high”.

As well as the update download, Microsoft also offers the perhaps surprising workaround of disenabling the anti-phishing filter altogether – even though it was a main reason for IE7 being introduced in the first place.
