As I said in the other forum, the empeg is the least of your worries. You need to seriously check the computers on this local network for infection.

I don't know if this is happening at your home or at your work. If it's at your work, you need to talk to your network administrator and tell them that there's infected machines trying to infect other machines. If it's at home, you DESPERATELY need a NAT-and-Firewall router sitting between your local LAN and the rest of the internet. I recommend the Linksys BEFSR41 or BEFSR11.
