1. shoot your son
2. take corrective action on your son's pc, up to and including locking 
it down.
3. I don't know the proportions of viruses today but not every one will 
infect others on a LAN (local area network - what you have).
4. you aren't actually positive it's coming from you son's pc, correct? 
  Have you researched the type of virus?  That may give you a better 
idea of where it came from and how to protect against it in addition to 
eradicating it.
5. if your router allows VLANs, you can put him on his own VLAN (kind of 
like his own channel).
6. Purchase an additional router that will isolate him from the rest of you
7. depending on the type of virus, putting him in his own IP range *may* 
help, if your router will allow it.  If not, the additional router will.
8. Make sure his pc has a good antivirus and firewall.  I haven't used 
the one you mentioned but I tend not to trust that brand.  There are 
very good free alternatives (AVG, Clam, Comodo firewall and others).


Good luck.
