Kerio Firewall for non-genuine windows?

Right now, I don't have a genuine copy of Windows XP because I don't have $200 for it and I need a firewall that can help stop viruses and spyware from coming onto my computer and is not really bothersome or changes the way sites load up.

I recently downloaded Kerio Sunbelt Personal Firewall version 4. On certain sites, it doesn't load all of the photos and when viewing a video on YouTube, the page looks different then when the firewall is disabled. And sometimes it seems to take a bit longer to load some pages. Has this happened to anyone who has ever tried the Sunbelt Kerio Personal Firewall? If anyone can recommend a better firewall, could you please mention it here? Or somewhere that might have a genuine copy of windows for a less price?
