Malware is an umbrella term used to describe any malicious software designed to harm, exploit, or extract sensitive data from a system, device, or network. Cybercriminals steal data like passwords and payment details by using malicious software. Nowadays, most hackers are professionals whose motives are stealing something of value. So, let’s learn more about the types of malwares, how it spreads, and how to protect yourself against it.
The motivation of cybercriminals is almost always financial gain. Some common reasons for using malware are:
There are many ways in which malware spreads into our devices:
Purchasing an app from an official store is generally a safe thing to do. However, there may be some apps coming from less trustworthy sources-these may contain malware.
Online advertisement that contains malware is called malvertising. The infected ad may be part of a legitimate website, which makes it hard to recognize. They may infect your device merely by clicking on the website, or after you click on the ad.
Computers 101—don’t click on links or open attachments in emails from suspicous sources. They probably contain malware. Unfortunately, phishing emails are getting harder to detect as they often appear to come from trusted sources.
Fake Software Installations
Sometimes malware can be disguised under the word “free”—free song, free movie… It is only after downloading your free file you realize that the only thing you got for free is a virus.
Infected USB Drive
If hacker needs physical access to your computer, they will plug an infected USB drive into your computer. Such USB drive contains malicious code which will unleash upon opening certain file.

Adware is software that targets you for advertisements. Malicious adware bombards you with infected ads that harm your devices. Free apps sometimes use adware to generate revenue—it’s not always malicious.
Ransomware blocks access to a computer system until a ransom is paid. You may be asked for cryptocurrency in exchange for access to your data.
Scareware basically scares you into downloading and buying a fake anti-malware software. It makes you think that you were infected but tricks you into truly getting infected by downloading malicious software. It typically looks like a pop-up ad that impersonates anti-virus companies informing you that your system’s files have been infected.
Spyware secretly tracks your activity and captures your sensitive data. Your information is then relayed to data firms, advertisers, or sold on the dark web for profit.
A Trojan horse works just like the mythological Trojan horse. It creates a backdoor in your computer and gives hackers unauthorized access to your computer system.
A virus is a self-replicating malware that inserts its code into other programs. Emails, flash drives, or websites may spread a virus. The virus activates by opening the infected file. It can delete files, modify applications, and cause system malfunctions.
A computer worm spreads from system to system without human assistance. It reproduces itself and exploits security software vulnerabilities. A worm can steal data, corrupt files, and install backdoor access to your computer.
