Internet IE6 crashes

[monsitj]

Good day,
I'm having a problem: every few days, when you start IE6 or Firefox (or simply click on the page) application hangs. And it can not be disabled by using Task Manager (receive an error message and the process is not turned off).
Do not restart itself, but hangs on the screen "closing network connections".

Hi,
