I have a Linksys BEFSR41 Firewall/Router. Normally, if I were to go to www.grc.com and run the "Shileds Up" test, all of my ports show up as "Stealth". BUT...

I got an IRC related virus, it put IRC on my pc and also did something to the Linksys box. I have reinstalled the firmware on the router, but when I do a test on www.grc.com the IDENT port 113 shows now as "Closed" versus "Stealth". Linksys has no response.

I can get to the internet as always, but I have this one port as showing as described above. No viruses I can speak of, I have scanned with Norton, Ontrack, and also Housecall.

Do I dare do more research on the IRC related virus? Could it have done something to my hardware firewall?

I thank you all in advance, the Linksys firmware is the December 13th, 2002.
