Computers are great machines that are becoming more and more important in our lives. However.., these machines can also be vulnerable. When their security is compromised, the situation can quickly turn into a disaster: ransom demand, data leakage, takeover, denial of service …
The Threats to PCs, smartphones and other servers are as numerous as they are diverse. Among the most fearsome are malware.
What is malware?
In English, the term malware is a contraction of “malicious software”. In French, we use the term “malware”, contraction of “malicious software”… . This term refers to all malicious computer code or programs that can be dangerous to computer systems.
The malwares are hostile, intrusive, and designed to invade, damage or disable computers, networks, mobile devices and other servers. Typically, they allow the cybercriminals who deploy them to take control of the machine remotely and interfere with its operation.
Many times, malware is designed to extort money from the victim.. It is capable of stealing, encrypting, or deleting data. It can also tamper with or disable key computer functions and secretly spy on computer activity.
What are the different types of malware?

The Trojan horses are also among the most renowned malwares. Disguised as legitimate software, or hidden in legitimate software, they act discreetly and create backdoors in the security of a system to allow other malware to enter.

Ransomwares have been booming due to the emergence of Bitcoins and other cryptomoney that allow hackers to recover ransom in an untraceable way.
The “Adwares” are not necessarily malicious, but they are particularly aggressive adware capable of bypassing the security system just to run ads. In addition to being annoying, they can open the door to more dangerous malware.
Finally, let’s talk about Botnets: infected computer networks used to work together under the control of a cybercriminal. In particular, they are used to orchestrate DDoS attacks.
