What is malware?

Malware is short for “malicious software.” It refers to programs designed to harm, disrupt, or gain unauthorized access to computers and networks.

There are several types of malware:

• Viruses – Attach to files and spread when executed
  
  

• Worms – Spread automatically across networks
  
  

• Trojans – Disguise themselves as legitimate software
  
  

• Ransomware – Locks files and demands payment
  
  

• Spyware – Secretly collects user information
  
  

Malware can infect devices through unsafe downloads, phishing emails, infected websites, or compromised USB drives.

Once installed, malware can steal data, slow down systems, spy on users, or damage files. Ransomware attacks, in particular, can cause major financial losses.

To protect against malware:

• Install antivirus software
  
  

• Keep operating systems updated
  
  

• Avoid downloading files from unknown sources
  
  

• Use strong passwords
  
  

In summary, malware is harmful software designed to damage systems or steal information, and it can be prevented with proper cybersecurity practices.
