Malware, short for “malicious software”, is computer programs developed with the intention of damaging, infecting or compromising systems, devices or networks. They can be designed to steal confidential information, spy on user activities, interrupt normal operations, cause damage to systems or spread to other systems.

There are several types of malware, each with its own form of attack and purpose:

Viruses: Programs that attach themselves to other files or programs and spread when those files or programs are run.

Worms: Malware that automatically replicates and spreads across the network, often without requiring user interaction.

Trojans: Appear to be legitimate programs but contain malicious code. They can steal information, open doors for other malware, or cause damage.

Ransomware: Blocks access to user or system files and demands a ransom to release them.

Spyware: Monitors user activities such as browsing history, keyboard typing and collects personal information.

Adware: Displays unwanted advertisements and often collects data about user browsing habits

Botnets: A network of infected devices that can be remotely controlled by an attacker to carry out malicious activities such as DDoS attacks.

Keyloggers: Record user keystrokes, capturing passwords and other confidential information.

To prevent malware, here are some important measures to consider:

Keep software up-to-date: Keep your operating system, programs, and applications up-to-date to fix known vulnerabilities.

Use antivirus and antimalware software: Use trusted security solutions and keep them up to date for real-time protection.

Beware of downloads and attachments: Avoid downloading files or programs from untrusted sources. Do not open suspicious email attachments.

Safe Browsing: Use up-to-date browsers and avoid clicking on suspicious links. Check the authenticity of websites before providing personal information.

Strengthen passwords: Use strong, unique passwords for each account, and enable two-factor authentication whenever possible.

Regular backup: Make frequent backups of your important data so that in case of infection, you can recover data without paying ransoms.

Attention to public networks: Avoid accessing sensitive information on public and unsecured Wi-Fi networks.

Education and Awareness: Stay informed about the latest cybersecurity threats and practices. Be aware of signs of possible attacks.

Remembering that, although these measures help to reduce the risk of malware infection, no approach is 100% foolproof. Therefore, constant vigilance and the adoption of good security practices are essential to keep your systems and information safe.
