The start page of my browser has changed to protectionband.com. Could you please tell me how this could have happened and how can I rectify it?

Your computer has been infected with a trojan called Zlob. Zlob hijacks your homepage to protectionband.com and generates warning messages to try and get you to buy fake programs such as SpyDawn, SpyHeal, Antivermins and others. You just dont need to get rid of protectionband.com start page, but also the Zlob Trojan that implanted it there.

You can use SpyBot S&D or Ad-Aware SE Personal Edition to get rid of it.
