Norton Internet Security causes my computer to crash

Hello, I'm writing from Greece, in order to share my problem. Some days ago (April the 14th actually), I renewed my long-expired subscription. Everything was fine, and I downloaded the Software, only to discover that trying to run a virus scan made my computer crash (blue screen appeared as soon as I run the scan). As a consequence I had to uninstall Norton and install another antivirus Programme. My question:  is Internet Security incompatible with HP notebooks? Does it have some kind of bug? I'd also like to ask if I could get a refund. Thanks in advance.
