Scary IE message (SOLVED)

As a fan of Fire Fox I thought to myself just now that I had better preview all my hard work in IE.

And this is the scary error message that came up

So I ran a joomla performance scan and this is the result



How the frickity blink can 2 script files be 74k when the recommended is 10?????!!!

I have the Equalizer template for J1.5 and on front page I have changed the header for a small animated gif

I also have:
suckerfish menu
jweather mod
jpowered scrolling script embedded in an image
Whos Online
Login

There are 5 frontpage articles - the leading one being the one with the scrolling script in.
AND I was planning on using Image slider on the front page too.

Error messages like that make me really nervous and Im presuming the problem is what has been outlined in the joomla performance reuslts.Of course I could be totally wrong and its nothing to do with that at all.

Either way can somebody please help and advise me what to do.


Edited to say:

I just re-read what Id typed and realised it was about as clear as mud. I apologise (too much caffeine) let me be more clear.

is the error message a direct result of the script file being so big? If so HOW and WHY is the script file so BIG and how do I go about resolving this.

Thanks for your time
