No Local Connection

Hello everyone,

 

I did a complete recovery of my 4700 because of a Trojan horse virus.  I tried repairing it to no avail so the next best thing was to do a reinstallation.  Now I cannot access the internet as "Other devices" and everything under it has a yellow question mark.  I read that I should install chip drivers, I did  and still have the yellow question marks.  My computer is out of warranty and I was wondering if anyone knows what my next step should be?  I did call SBC DSL they said they can't help me until I get a local connection on my computer.  Any help is appreciated.
