Right, came home from work, popped into my room to see how my downloads were doing, and saw that I was downloading at a grand total of 5k/sec.

Tried to fire up a few websites, nothing.

Checked my connection status on the firewall web interface, and found a mad frenzy of UDP Flood crap in the log, the only way I could get everything running properly was to disconnect and reconnect.

The log above is admittedly tiny, but it's all I was able to retrieve, I have removed my IP info for the sake of common sense. :)

So, anyway, onto the point, what the hell is a UDP Flood?

I'm thinking it's some kind of DOS attack, seeing as though all it seems to be doing is slowing my connection, my last full virus scan was friday, and I'm running another one now with fresh dats, but I just wondered if anyone could shed any light on the subject?

It's a ping attack. Someone knew your ip, created a ping batch file. Open 500 batches and lagged you down. I think that uses TCP and not UDP. I'm not sure. Someone correct me.
