Malware is everywhere now that computers, smartphones, and the internet are used for almost everything. Malware is software that harms computers, steals data, or does other bad things. Malware is a digital disease that can damage your devices.

Forms of Malware

Malware types are viruses, worms, Trojans, spyware, ransomware, and adware. They are all developed with the intent of installing and performing activities on a victim’s computer without the user’s consent, regardless of their purpose.

Viruses: Computer viruses replicate themselves by infecting other files at users action – they need a user or system to trigger them, such as clicking an executable file, before they can spread. They can damage or even destroy your system.

Worms: Network-spreading worms that self-replicate and propagate themselves. They slow networks, disrupt internet connectivity, and crash systems.

Trojans: Trojans, named after the Greek Trojan horse, masquerade as legitimate software while committing crimes.

Spyware: These is a malware that covertly steal user data, including passwords, credit card numbers, and other personal data, by tracking user activities.

Ransomware: In simple terms, an attacker encrypts your data using ransomeware and demand a ransom to decrypt it. This has been dicussed in detailes in my Ransomware post.

Adware: This malware displays unwanted ads on your computer or mobile device.

Malware Prevention

Update and Patch Software: Updates means installing the latest version of the software and patching means applying security and bug fixes released by the developers. Updating and patching your operating system and software can fix vulnerabilities and prevent malware from exploiting them.

Using Antivirus Software: Antivirus helps to detect and remove malware. You should install it on endpoints, especially in users’ spaces.

File Downloads awareness: Do not download unknown or unsolicited fileds if the source cannot be verified. Always verify files sources before you open them.

Firewalls: activate firewall rules to allow only known IPs, URLs and protocols. Implement network segretion using firewall so that if a segment of the network is infected by malware, hosts in that segment wiill be prevented from communicating with other systems.

Use Pop-Up blockers: Adware mostly use pop-ups that interfere with your browser screen in a very annoying way. Pop-Up Blockers and browser browser extensions that block unwanted and potentially harmful ads.
