I wake up one morning and my PC is fine. Get back from classes, run AVG, adaware, spybot, and CWshredder to get rid of my hijacked homepage, reinstall WMP because it quit working, and with AVG found a virus called downloader.esepora.k. I reboot and I can't connect to the net anymore. No clue why I can't. My internet works because I hook my laptop up straight to it and it's fine. I'm on a college network. I also a few days ago set up a wireless router. Uniden. After I started getting the problem I unhooked it though, thinking it could be the problem, but I don't think it is. Dunno if the router or the trojan or something else could have screwed up my settings? My computer still responds when I unplug the ethernet cable or plug it in. Just no activity. Things I've done to try and solve the problem:

#1. Repair LAC - get error msg (Cannot renew ip)
#2. goto cmd. ipconfig /renew - get error msg (Similar to above, says it timed out.)
#3. Running a program called LSPFix (Didn't fix anything)
#4. Go into admin tools> services> dhcp client> set to automatic and start it (These settings were already correct)
#5. Get the IP, Gateway, router, and DNS addresses from my laptop, and hard coded them into the tcp/ip settings of my desktop's ethernet card. (Didn't work. It only took longer to realize it didn't work when looking up homepages.)

I'm clueless on what to do next. I'm thinking reformat, just don't want to have to go that far. Anyone got any suggestions?
