I’m trying to fix my father-in-law’s computer. He had Mcafee, it wasn’t working correctly and his internet would not connect. I completely removed Mcafee but the internet still would not connect. I ran Dr Web because that was the only antivirus I had on a disc and it found some Trojans (7 total). I deleted them but it still will not let the internet connect. I know that the connection and modem is working because I could use Mozilla Firefox when in Dr Web mode.
What are some things I can check? I forgot to check the firewall, which could be the problem but what else? Is there a way to download IE to a CD and reinstall it? Is this a normal problem sometimes after having a few trojans?
