Maybe this is a stupid question, but if there is that much matter balled up in one spot, shouldn't its own gravity hold it together? What could cause such a massive explosion?
I probably wouldn't bother with solutions like McAfee. Basically the strongest protection you can currently have for a home wireless network is WPA. If your router is newish (last couple of years) it will probably use WPA. If you're still using WEP (older routers) it's probably worth upgrading, as WEP has shown to be able to be cracked within a few minutes. WPA is much stronger (crackable, but stronger). There are also things you can set up like MAC address filtering and hidden SSIDs, but any hacker worth his salt will be able to get past them quite quickly anyway, so there's not much point. In conclusion, just make sure that you're using WPA with a strong password.
It depends on the rubber seal that goes around the actual piece of glass. If it's providing a good seal you should not see and leakage inside the car. Those blowers that they use put out a TON of air, this could have been why the seal was broken, too much pressure.
