AOL Explorer stole my Internet access and IE doesn't work

One of my kids accepted the AOL explorer on my laptop. Once installed it disabled IE and only AOL programs can access the Internet. I uninstalled AOL Explorer (finally) but IE still doesn't work (AOL does). When I run network diagnostics the Network adapters, DNS servers, Default Gateways, and DHCP servers are FAILED.
