Should I be concerned about a Decompression Bomb error?

Hi. I ran an Avast scan earlier today, and received this message because a file could not be scanned:

Should I be concerned about this error message? I have never seen this sort of thing before, and I don’t have any idea what a decompression bomb even is to begin with. I’m on a PC that I built a while back, and have had no previous issues with Avast on it.

Considering that many users here seem very informed about Avast, is there anything I should or have to do about this? I am new to this forum so any advice would be great. :slight_smile:

How do I handle files that avast! can’t scan? https://blog.avast.com/2014/02/28/how-do-i-handle-files-that-avast-cant-scan/

and I don't have any idea what a decompression bomb even is to begin with.
It is a compressed file that will unpack to a very big file so avast scan engine will not unpack and scan it

ZipBomb (decompression bomb) was a trick used in the old days to crash the unpack/scan engine and make way for other malware. Have never seen a real one and avast is the only one i know that use this scan Error name
