What is "google not working"? Is that some google app or just the web page?
There are long discussions about malware and such but given only what's in your post, you see the need for more detail.
There are also long discussions about Explorer's issue with video files which stretches all the way back to 1995 so I wonder if it's the same old thing.
google not working.It happens everyday,multiple times.I have W7& internet Explorer 9.
ANY help appreciated,it's driving me up a wall.
