And did you try this PC set to the usual 18.104.22.168 and 22.214.171.124?
This all started when the computer had the Google redirect virus, which I attempted to remove with super antispyware pro. When the virus was gone, I decided I didn't need the antispyware anymore and so I removed it. When I did that it "un-quarantined" the files it had removed. Then the computer couldn't establish a connection (with the router I assume?). I uninstalled the ethernet controller which fixed this problem on restart. But now I have a DNS lookup failure. I know it's not the router as I can connect other computers to the internet via wireless and ethernet connections. Any help would be appreciated as I have been googling all day to no avail.
