Types and Categories of Malware 

Viruses 

Viruses are a type of malware that attach themselves to legitimate programs or files and spread from one computer to another. They can corrupt, delete, or modify data and often require user interaction to activate. 

Worms 

Worms are standalone malware that replicate themselves to spread to other computers. Unlike viruses, worms do not need to attach themselves to an existing program and can propagate without user intervention. 

Trojans 

Trojans, or Trojan horses, disguise themselves as legitimate software but carry malicious code. They can create backdoors, steal data, or cause other harm once activated by the user. 

Ransomware 

Ransomware encrypts a victim’s files, making them inaccessible, and demands payment for the decryption key. It has become increasingly prevalent and can cause severe disruption and financial loss. 

Spyware 

Spyware secretly monitors and collects user information, such as browsing habits, login credentials, and personal data. It often operates undetected and can lead to privacy breaches and identity theft. 

Adware 

Adware displays unwanted advertisements on a computer or mobile device. While not always malicious, it can be intrusive and may be bundled with spyware or other harmful software. 

Rootkits 

Rootkits enable attackers to gain administrative control over a system without being detected. They can hide their presence and the presence of other malware, making them particularly dangerous and challenging to remove. 

Keyloggers 

Keyloggers record every keystroke made on a computer, capturing sensitive information such as passwords, credit card numbers, and personal messages. They pose significant risks to user privacy and security. 

Symptoms and Signs of Malware Infection 

Slow Computer Performance 

One of the most common signs of malware infection is a noticeable slowdown in computer performance. Malware consumes system resources, causing applications to run sluggishly or freeze. 

Unexpected Pop-ups 

Frequent and unexpected pop-up ads, even when not browsing the internet, indicate potential adware or spyware infection. These pop-ups can be intrusive and lead to further malicious sites. 

Frequent Crashes 

If your computer frequently crashes or displays blue screens of death (BSOD), it might be due to malware interfering with system operations. 

Unusual Network Activity 

Malware often communicates with remote servers, resulting in unusual network activity. Monitoring network traffic for unknown connections can help identify potential infections. 

Unauthorized Changes to Settings 

Malware can alter system settings, such as disabling security software or changing browser configurations. If you notice settings changing without your consent, it may be a sign of infection. 

Disabled Security Software
