Hi! I am sorry, I am not sure if I should post this here. But anyway, I have been facing this problem with my PC recently. I am a XP pro user and the browser will always close down in the midst of me surfing the net. Also, I used to be able to view other languages like thai and chinese by changing the encoding to the particular language, but recently it is no longer able to do so... all the foreign words are displayed as ??????
Can someone advice me on this? Thanks!

I would get a good spyware tool and make sure that you haven't got any spyware/malware on your machine.

Adaware 1.05 (www.lavasoft.de) is a really good one.
