Malware
You deserve IT consistency with a LOCAL human face!
Malware, short for malicious software, is any type of software designed to harm or infiltrate a computer system, network, or mobile device without the user’s permission. Malware can take many forms, including viruses, worms, Trojans, adware, spyware, and ransomware. It can steal sensitive data, corrupt files, hijack user sessions, and cause system crashes, among other things. In this article, we will discuss the different types of malware, their effects, and how to protect yourself from them.
Viruses
A virus is a malicious program that spreads by attaching itself to other programs or files. It can replicate itself and spread across multiple devices, causing damage to your files, applications, and system software.
Worms
Worms are similar to viruses but do not require a host program to infect a system. They spread through networks and exploit vulnerabilities in software to propagate themselves.
Trojans
Trojan malware masks itself as legitimate software, tricking users into downloading it. Once installed, it can allow hackers to gain access to your system and steal your data.
Adware
Adware is software that displays unwanted advertisements on your device, often collecting data about your browsing habits.
Spyware
Spyware tracks your online activity, such as your browsing history, keystrokes, and passwords, without your knowledge.
Ransomware
Ransomware encrypts your files and demands payment in exchange for the decryption key. If you do not pay, your files may be permanently lost.
