PC whizzkids: I need some help!
I visited a friend of mine today to fix his PC, it was infected with loads of trojans, virii and backdoors so I decided to format the HD and start all over again.
When I left it was running stable but he just called me and keeps getting "dns errors" when surfing, no matter what site he tries to get (yahoo.com / microsoft.com / google.com) he keeps getting the same error.
When I left internet worked like sunshine and nothing seemed wrong, can anyone help me out?
