I seem to be unable to open any attachments in my yahoo mail account. It just does nothing once I click the "download" option. I have IE9 & Kaspersky Internet Security, I know Yahoo uses norton to scan emails and so it might conflict with what I have but I tried even with it disabled and it doesn't work. Tried erasing history, cache & cookies and so on and it makes no difference, even installing Chrome didn't work. Not sure what else to do, my work sends me shift times so I can't check my rota if I can't open attachments. Help will be much appreciated.
