Its ZIP or RAR files may, therefore, have but a small size. The code is grouped into simplified, smaller fragments.

A decompression bomb’s structureĪ decompression bomb generally generates a long-pattern code. The chances that such software will involuntary miss the virus, are almost absolute. While you may be weary, therefore, of the files you unzip, your antivirus may proceed with scanning it before you’re sure about its safety. A virus hidden within myriads of files may not be easily traced, if at all it can be found. It is unlocked or released into your system upon decompressing it. A virus could be hidden within those trillions of minimized data, which may eventually harm your system.Īs the name suggests, such a virus hides within a compressed file. If the files are too large upon unzipping, they can overload your antivirus or system. It will also decompress or open the zipped. How?Īntiviruses scan all files, including those downloaded. Should you scan such an infected file, your antivirus will potentially crash. The problem with reducing the size of binary fragments is that it can make an overly huge file seem small, while in the real essence, it is just minimized. A code fragment could have sets of repeated numbers, which in basic compression algorithm, will be rewritten to become smaller. The larger a file is, the longer its code could be. Your system’s files are stored in a series of code, represented by 1s and 0s. Let’s briefly talk about binary codes and their relevance to decompression. Compression technology rewrites a file’s binary code fragments, so that it is smaller.

To make them more or easily manageable, such files are compressed. They would both definitely need large storage. Imagine downloading a whole television show with over twelve episodes, or a high-graphics game. Large files will often come compressed to not only make downloading easy, but also transfer and to save on storage. You have probably downloaded a ZIPped or RAR file at one point or another. What then is this ‘compression technology’? Compression and Binary But did you know that not all scans on your system will keep you protected? A decompression bomb is a file that by design is meant to crash your antivirus and ultimately, system, by the use of compression technology.
