Intrusion - I'm under attack!

Hi all,

 

Something has changed recently and I'm under attack!  About two weeks ago,  something caused my Internet Security 201 to keep popping up alerts.  Here's a screen shot of the history log from this afternoon.

You can see that the attacks are frequent,,,and appear to me to be mlaicious in nature.  This has only nbeen apparent for the past couple of weeks.  Also,  my computer has been acting a little strange (wierd little things...won't hibernate, fonts changing in my browser)

 

Has anyone seen something like this before?  I've got a feeling that MY computer is sending out hidden requests...but I've done multiple scans and nothing abnormal is being detected.

 

Any help would be much appreciated!
