You may have heard the phrases ransomware, trojan, and virus in the news headlines and wondered what they meant. All of these terms refer to a sort of malicious software that is used to infect computers and gadgets.

Malware (short for malicious software) is quickly becoming one of the most serious online threats, and it has been employed in some of the world's largest cyber-attacks, like the 2017 WannaCry incident, which affected over 200,000 people in 150 countries.


Malware is often placed on a computer when a user clicks on a malicious link, downloads a malicious attachment, or launches a rogue software application. Once installed, the virus may be used by attackers to spy on your online activity, steal personal and financial information, or exploit your device to break into other systems.
This type of assault has proven to be quite profitable, and it is growing more sophisticated as thieves combine old and new types to maximize harm.


Malware comes in a variety of flavors, with some being more dangerous than others. Every day, 230,000 new malware samples are created, and each outbreak has its own unique method of infecting and harming systems. The following are the most frequent forms of malware:




A computer virus is a sort of harmful software that, once triggered, replicates itself from folder to folder, injecting its own code along the way. A virus has the ability to propagate quickly and will often infiltrate a system with the goal of stealing personal and financial information, spreading spam, or shutting the machine down.




A worm, like a virus, replicates itself within a system, but unlike a virus, it does not propagate to other applications. Once installed, the worm begins stealthily infecting the system without the user's awareness. Worms have the ability to duplicate themselves hundreds of times, draining system resources and causing gadget damage.




A Trojan is a form of the virus that masquerades as legitimate software while really serving a malevolent goal. A Trojan may masquerade as a free update, game, or anti-virus application in order to mislead the user into installing it on their device. Once installed, the Trojan discreetly works in the background to steal sensitive data, install a backdoor, or do other destructive acts.




In recent years, ransomware has become the virus of choice, and it is anticipated to cost the globe more than $8 billion in damages by the end of the year. Ransomware is a sort of malicious software that encrypts the data of a victim and prevents access until a ransom is paid. The most typical way for ransomware to be delivered is through clicking on a link within an email or opening a malicious attachment.


Methods to fend off a Malware Attack

  • Get an Anti-virus software

Installing anti-virus software is one of the most important strategies to guard against malware. Anti-virus software helps safeguard your device against dangerous malware that might compromise the system. It will check your computer for malware and clean it up, as well as provide automatic updates to protect you from newly generated infections.

  • Keep your software updated 

In addition to installing anti-virus software, it is critical to keep your software up to date in order to prevent attackers from obtaining access to your computer through weaknesses in older and obsolete systems.

  • Avoid clicking on suspicious links and phishing scams 

Phishing is still the most convenient technique for hackers to install malware on your device. Phishing schemes entice consumers to read emails or click on links that look to be from a credible business or reliable source. The link might send you to a false website where you are encouraged to provide your personal information, or it could connect you to a website that directly infects your machine with malware. If you're unsure, don't click the link.

  • Deploy Email Authentication 

With the rise of email-based phishing scams in recent years, it becomes fairly obvious that email authentication is the best way to avoid such scams. Protocols like DMARC, SPF, DKIM, and BIMI help you keep hackers at bay and help you ensure the safety and security of your sending domains.

  • Keep Extensive Data Backups

Backing up on a regular basis ensures that you can still recover all of your vital data and files if your computer becomes infected with malware. This will assist to limit any harm and prevent you from being a victim of a ransomware assault.
