I was working on a laptop that had been infected by a virus. I copied the data files from the laptop onto a flash drive and then I did a scan of the files to make sure they were clean. Nothing came up. So, I put the flash drive into my computer to copy some drivers onto it.

Little did I know, the file was well hidden and spreads via USB port. So, as soon as I plugged my flash drive into my computer it was on like donkey kong. To make matters worse, I am an administrator so because I have elevated rights it made it easier to spread the virus.

And in case anyone wants to know, it's a variant of the Conficker worm. The network team was here all night trying to clean everything up as best they could be they had to disable the network ports for a lot of machines because they weren't able to remotely clean them.
