how do I get rid of flash mall pop up?

This has nothing to do with Classic. Flash is an Adobe animation software used for animation and audio links on web browsers.

Go to Apple menu -> About this Mac, and verify your signature is correct. If it is, please post in the right forum:

I went into my applications folder and found the icon for flash mall right there. It looked like a yellow light bulb and clearly labeled. I simply dragged it into the trash!
