How is a Spacefiller virus different from other viruses?
Alternatively referred to as a cavity virus, a spacefiller virus is a rare type of computer virus that trys installing itself by filling in empty sections of a file. By only using empty sections of a file, the virus can infect a file without the size of the file changing, making it more difficult to detect.

What is a spacefiller virus?
A Spacefiller (Cavity) virus tries to attack devices by filling the empty spaces present in various files. That’s why this rare form of computer virus is also addressed as a Cavity Virus. Its working strategy involves using the empty sections of a file to house a virus, without altering its actual size. This also makes its detection quite ...
How does Spacefiller work?
Before infecting any device, the Spacefiller virus looks out for space in a device where it can attach its malicious code. If at all it is not able to find a definite amount of unused space on the device it reruns its search to look out for the place where it can house its malicious codes.
How does the Cavity virus work?
A normal computer virus simply attaches a program code to a file which results in increased file size. This also increases the chances of detection.
When was Spacefiller first detected?
Spacefiller virus was first detected in 1998 and infected multiple Windows versions including 95.98 and ME. Its malicious effects can range from infecting devices with malicious code, overwriting of data stored on your device, and tampering with the device BIOS.

Why is Spacefiller called Spacefiller?
The name "Spacefiller" was introduced because most viruses write their code to the end of the infected file, with infected files being detectable because their file size increases. In contrast to this, CIH looks for gaps in the existing program code, where it then writes its own code.
What happens if a virus is overwritten with zeros?
For the first payload, any information that the virus has overwritten with zeros is lost . If the first partition is FAT32, and over about one gigabyte, all that will get overwritten is the MBR, the partition table, the boot sector of the first partition and the first copy of the FAT of the first partition.
