Every time I open a new tab in IE or Firefox it opens up a search engine. No where on the page does it state what this search engine is or where it comes from. The only thing you can see is that it loads from a website that starts with bigseekpro... When you search for something there the results come from this link : http://dealbd.mystart.com/search.php..._3mshp_04&q=aa

I tried to change the registry value for my IE tabs but that has not worked. I am not sure what is this and what exactly it is doing to my computer but I would like to get rid of it and I have not found a solution that works for me. I use Microsoft Security Essentials and it did not find anything. I recently downloaded Malwarebytes Anti-Malware and that has not taken care of this either, though it did apparently find some other things.

All the computer experts out there, your help would be much appreciated. I am operating a windows 7 64-bit system.
