Redirect from Pay Pal and Norton stopping a malicious attack

This is so weird.  This is the second time that I've attempted to open my browser in IE to go directly to Pay Pal and a malicious attack has been stopped Thanks to Norton!  I'm wondering if anyone else is experiencing this problem.  I'm completely baffled now and afraid to go to Pay Pal! I know that Internet Explorer is not the best but I use Explorer 11.  Maybe this is the problem.
