microsoft hotmail isues

Hello forum,

I've had a problem with my Hotmail account for about a week.  I can't open an activity on my personal calendar.  No matter how much I click, I can not open.  Also, the actual email messages are hard to load (if at all).  There appear dots on the top of the screen that move from left to right.  I believe I may have a virus that was not caught with my virus protection.

What help is there to correct this?  I have even retyped msn.com in the bar to start over, but that didn't work.

Thanks in advance if someone may know.

Gary
