Compression Bomb

Can some one please shed some light on a subject for me. I have Avast home prof version and when I run a virus scan it comes up with the results as such: Can’t scan file compression bomb with a file number. I can’t remember the numbers right now but can anyone tell me what a compression bomb is? Is it a virus and if so how do I get rid of it. I can’t find any reference to what this is on the net.

Thanks for your help.
