Yesterday, I was working on the computer, working in yahoo and going to my email.  I had no problems at all.  Then last night my wife was going to go on to her yahoo mail and it just wouldn't go.  I then tried and it didn't work.  I went into my yahoo mail and now it wouldn't work.

Everything else popped right up but Yahoo Mail.  Now, My Yahoo home page is very slow to open if it even does open up.  

No matter what I do , I can't get Yahoo Mail to open.

I did a scan and it showed no virus or malware.  I've cleared the cache. I have tried all the browsers there are.  None work with Yahoo Mail.

I have an Asus RT-AC86U router and a Netgear Modem.  

I have tried everything I know.  What can I do?
