I see, the problem is clear to me now - Open IE | Tools | Internet options | Change your homepage to www.google.com
Now, check the homepage in the registry:
If this is marked as google.html, either clear it or change it to www.google.com.
Also, you don't need to be premium to upload files to megaupload.com:
http://www.megaupload.com/ | Browse - choose the file to upload | enter a description | send | paste the URI you're given.
