Unable to send mail from outlook and unable to login to cox.com

I have been unable to send email with outlook from my cox accounts for weeks. In addition I cannot login to cox.com. I am getting the error Make sure you’ve got the right web address: https://idm.cox.com
Search for "">https://idm.cox.com" on Bing

I can login on my work computer when it is on my home network. I have called support. I have flushed dns. I have rebooted numerous times. I have quickly temporarily disabled avg anti virus. Is there any way at all to resolve this problem. Webmail works but really STINKS. I have multiple accounts and Outlook is a superior program.
