Spimware infection

[Wallace Aiken]

Hi, I'm using two of your firewalls...they work great. But all of a sudden they're showing signs of "Spimmware" infection, a kind of spyware. 

I work for Kent State university and their network scan came up with the IPs and host names of my firewalls, as well as some other hosts on my subnet that were not behind the firewall...can you give me any advice?

Thanks!
