Discover the mysterious world of malware
Most of us are familiar with the term "virus", and many more have heard of spyware. However, the threat is not limited to these two categories. Have you ever encountered terms such as rootkits, botnets and rogues?
Let's see here a brief introduction to the diversity of malware.
- Computer viruses : The term "virus" is frequently used to refer to all types of malware. To be specific, a "virus" is a type of malware designed to replicate itself by infecting other programs.
- Computer worms : A worm is a program that spreads through a computer network. It uses the internet in all its forms (emails, websites, etc.) to disperse.
- Downloaders : This is a small executable file. Once launched on your computer, it downloads another, usually more aggressive program, such as a Trojan horse or a rootkit.
- Rootkit : It is a set of software generally allowing to obtain privileged access, often called "root rights", on a computer, to install a backdoor and to erase all traces of these operations in the log files (logs) .
- Arrogant: This is software posing as a free antivirus, claiming that your PC is severely infected. It then offers to clean your system, prompting you to download these fake antiviruses.
- Ransomware : These malware are like kidnappers, they take your files hostage and demand a ransom to release them.
- Botnets : This software turns your computer into a puppet, controlling it remotely to perform all sorts of malicious activities without your knowledge.
Sounds scary, doesn't it? But don't worry, knowing about these threats is the first step to better combat them, and we're here to help you do just that.
