Different types of Malware:

  • Bug: Bugs are often accidental flaws in a programs source code impacting program usability, and in extreme cases, causing system crashes.
  • Adware: Adware, also known as advertising-supported software, displays advertisements like pop-ups.
  • Ransomware: Ransomware is designed to prevent you from accessing your computer until you pay a sum of money. This type of malware hit computers hard in recent months with ransomware outbreaks like WannaCry, Bad Rabbit, and NotPetya. Companies our individuals receive demands to hand over money for an encryption key to get their data back.
  • Root-kit: A root-kit accesses or controls your laptop or computer. Whoever has control of the rootkit is able to access files, modify the software and steal information.
  • Spyware: Through spyware, hackers are able to watch your activity without your knowledge.
  • Trojan Horse: True to its name, a Trojan horse is malicious software that disguises itself as an average file or program in order to trick users into downloading it.
  • Virus: A computer virus attaches itself to your files and slowly but surely spreads to other files. Eventually, all of your system’s files may be deleted or corrupt.
  • Worms: A worm can infect an entire network of devices through network interfaces.

As you can see there are lots of types of Malware and all the above software would have a detrimental effect on your productivity. In case of Ransomware you can be completely locked out of all your data and without a successful backup there may be no way to restore.


The ideal situation is to prevent infection, to do so please be vigilant with everything you download. Every email you receive ask yourself if you were expecting it if an email contains a link to a document don’t open it unless you can verify the authenticity.


You should always install an Antivirus and Malware protection, keeping adequate protection especially in a business environment is essential but can also come down to a Compliance issue. Not all Antivirus products protect you from the different types of Malware, please always be careful when choosing a product.
