Browsers closes without giving any notification

[mach04]

I have recently being experiencing that when visiting some web pages such as yahoo games, the pages I have opened suddenly closes without noticing, sometimes the rest are not closed. This does happens both to IE6 and Firefox 2.
I have ran several antispyware and an antivirus but none of them have helped me in this case. I have no problem using the pc nor going on internet. I am using XP home version.
I was wondering if someone know how to tackle this.

I did deactivate them one by one but nothing has happened. Along the programs that are installed on my pc, I see this one which I am not sure what it is for, MSXML 4.0 SP2, I am not sure where this has come from, is it ok to uninstall this?

That's a windows update that you should leave in place. There are several security fixes.
