I can't connect to the internet after removing a virus.

I recently had a pain in the butt virus that finally seems to be gone for good but now for some reason I can't connect to the internet.
I am getting this error message:

Windows cannot connect to the internet using HTTP, HTTPS, FTP. This is probably caused by firewall settings on this computer.
Check the firewall settings for the HTTP port (80), HTTPS port (443), and FTP port (21).

and then it says something about contacting your internet service provider.

I tried to do a system restore but for whatever reason I have never been able to do it on my computer. It will restart and say it was unable to do it. I wonder if I deleted something that should not have been deleted when I was trying to get rid of the virus.
Anyway, now my parents laptop (the only other way I can get on the internet) is messed up and I am here at school using the computers. The router is fine since I can connect wirelessly with the laptop, it's just something wrong with my pc that won't connect to the internet. It's not using wifi. I have it connected directly to the router.
 
I personally would format / reinstall but uninstalling the network card will also work (or should) friend had virus that i cleaned off his pc but still could not connect to internet so uninstalled nic and reinstalled and solved but still his usb verizon internet would not work so ended up doing reinstall was annoying but not shocking
 
I'm not really sure how to do that...i have the nic on the motherboard, so do you think the drivers or whatever I should need would be on a disc that came with the motherboard? I just want to be sure before I go home and start messing with it and have to come back here cause I didn't know what I was doing. 😱

ok I just looked up how to do it on google so I'll see how that goes.

If you're running winxp, download dial a fix and run the networking fixes there (located in the tools icon i believe, been a while...).

doesn't work in vista/7 tho.
 
alright i'll give that a try. I removed the NIC driver through the add/remove program thing, restarted the computer, and then it installed again after i put in the cd, but i still couldn't connect to the internet...
 
so i got home and ran dial a fix. i don't know if it even did anything but for some reason i can access the internet through Firefox. before, i tried internet explorer and google chrome and after that i just said whatever there is something wrong. i never even bothered to check firefox...so i have no idea why it works on firefox and nothing else. i am also able to use Windows Live Messenger and play online games...so i'm connecting to the internet but right now it seems to be just those 2 browsers...

Did you check the hosts and lmhosts files? They can be found under "C:\Windows\system32\drivers\etc"

Other than "127.0.0.1 localhost" these should be empty. Anything with a "#" at the beginning is a comment. There are several comments at the beginning of these files.
 
woohoo, the unchecking all the boxes in the LAN settings thing worked. and now google chrome seems to be working. the only thing now is that the zune media player won't connect to find album info but that doesn't really bother me. other than that, looks like everything is back to normal.
thanks for the help everyone

update: zune thing works now, must've been something else..

You're welcome 🙂
 
FYI on this...

I work on at least 1-2 computers a week to remove spyware. The newest crop of spyware (last 3 mo or so) is changing the settings for the proxy server in IE. Another little change that prevents a user from accessing the internet to download a fix 😉

Just another sign of the evil hack-losers evolving the software to make more $$$
 
I am with a previous poster. REload this ah heck.

The problem is that even you get this crippled system up and going what else is lurking that did not get fixed???

IMHO ...It is not worth it.
