b4 u start to do anything... just turn the firewall on then it won't affect you anymore..then go ahead and install the patch or just go to the task manager to dlt the worm... after u did all these.. turn off the firewall then everything will be in order again..

i agree with matfz , and installing the patch is a good way to go`~! because this worm is spreading very quickly~!
