Getting DNS error, afraid this is a malware issue.

Hey guys sorry if this is posted in the wrong spot. My computer is two years old and I've been getting lazy with protecting it. After seeing some threats blocked by AVG my browser started redirecting and then stopped being able to connect at all. Other computers on this wireless router are working fine.

I've run all the usual anti spyware programs in safe mode, cleaned the registry, and tried using a preferred DNS server to a fixed IP. Nothing's working. I'm using my gf's computer to research, download anti spyware programs and post on this forum.

if it helps this is the info I get when I run ipconfig:
