"An intrusion attempt...\DEVICE\...IEXPLORE.EXE" Help needed.

I keep getting the following warning multiple times when I use Internet Explorer 8.

 

"Ain intrusion attempt by 109.95.113.130 was blocked.  Application path \DEVICE\HARDDISKVOLUME1\PROGRAMFILES\INTERNETEXPLORER\IEXPLORE.EXE"

 

I have scanned my computer with Norton(even in "Safe Mode"), it didn't find anything.  I have even reinstalled Internet Explorer 8 and Flash.

 

What should do?
