From personal communication to financial transactions, we have come to rely much on digital technologies to keep many aspects of a normal life running. With this increasing dependence on digital technologies, comes along the rise of malicious software, commonly known by its short form – malware.
Malware is a broad category of software designed to cause damage and disrupt operations in computers. Once a malware is able to gain unauthorized access into a computer system, it is capable of performing a variety of “silent” malicious acts. The computer user may not even notice the presence of the malware until the effects are widespread.
Malware poses a growing threat to individuals and organizations, from casual Internet users to large businesses. This is why it is important to gain more understanding about the dangers of malware. If you intend to live well in the digital age, you must learn how to better protect your data, privacy, and financial security.
Types of Malware Threats
Viruses
Viruses typically require a user action (like opening a file) before they can infect files or computer programs. Therefore, you must always make sure that the files or programs are safe from viruses before you open them in your own computer.
Worms
Worms are self-replicating and spread across networks without any user interaction. Unlike viruses, they don’t need to attach themselves to another program, making them especially dangerous for companies with large interconnected systems. Basically, worms often exploit security flaws and can lead to network disruptions, data loss, or even system crashes.
Ransomware
This highly destructive form of malware encrypts a victim’s files, rendering them inaccessible. As a result, the victims are normally forced to pay large sums of ransom money or suffer extended downtime. Even if the ransom is paid, there’s no guarantee the files will be restored.
Spyware
As its name suggests, spyware is designed to spy on users by secretly collecting information such as keystrokes, browsing history, and passwords. Spyware is particularly dangerous because it can lead to identity theft, financial fraud, and corporate espionage. Worse still, the victim may not even be aware a data breach has occurred.
Trojans
Disguised as legitimate software, trojans create backdoors that allow attackers to remotely control the infected system. This gives attackers access to sensitive information or the ability to install additional malware. Trojans are often spread through phishing emails or malicious websites.
Tech Tip: Protect your online privacy.
A lot of what you do online is tracked. There is no way to completely block or avoid all Internet trackers, but you can at least use a Virtual Private Network (VPN). Use my affiliate link below to get your VPN offer and I may get a commission if you make an online purchase at Namecheap’s website.
