internet explorer page opens all on its on at 10:51 every night.how can i fix this and what causes this to happen

It looks like you have some spyware ticking away in your system. I would use the HijackThis program to post an HJT log in our Viruses and Spyware forum. Someone there will be able to offer more assistance than I.

You can find a link to hijackthis, along with other helpful advice and tools, in this thread:

Please post your hijackthis log in the Virus forum (not in this thread), and include the problem you're having.
