I never had a problem opening my AOL E Mails. Two days ago I found that I could not open them when they come in because when I click on them to read... I get all across the top of my screen.. the following: https://s.admathhd.com How do I get rid of that ? Any suggestions. Thanks. I am running Windows 7 and AOL.

Open control panel, select internetoptions. Click on security tab, select restricted sites, enter s.admathhd.com.
Click on privacy tab, click on sites add s.admathhd.com

Click apply and OK

Should do it

This solution didn't work for me. I have the same problem as OP

Any other ideas? This is a complete pain

That does not work for me either.
Any other ideas?

Here is what worked for me. Click on start and type in regedit. Under the edit tab, click on find and type in admathhd. Right click and delete the entries you find.

Be sure to click on "find next" after you delete. I found four entries of admathhd.

I was hoping so much this would work for me. But it didn't. This has been going on for a few weeks now. I have ran every malware, adware, virus program there is, and I still have these popping up all across my screen every time I open AOL Mail :-(
