Default IE Page Pops Up

I have a strange phenomena on my PC.

1. The default homepage of IE goes to http://talk2namratha.googlepages.com
2. This IE window popsup every few minutes also.

This is highly irritating and I am at my wits end.

I must mention here that I use only Firefox for browsing and therefore find this pop-up page highly frustrating.

Please help.

Thanks
