Malware is simply put malicious software, software that is created to bring harm to a computer. Malware can be in the form of worms, viruses, Trojans, spyware, adware and rootkits, etc., which steal protected data, delete documents or add software not approved by you.

Common types of malware:


Understanding the difference between malware and viruses is very important. A virus is just one type of malware, but the term is more widely used by the public. The term malware refers to any malicious software, including a computer virus.

  • Ransomware:
  • Ransomware is an advanced type of malware that restricts access to the computer system until the user pays a fee. Your screen might show a pop up warning that you have been locked out of your computer and that you can access only after making a payment.

  • Spyware:
  • This type of malicious software, spies on you, tracks your activities, spyware’s presence is typically hidden from the user. Some spyware like key loggers may be installed intentionally in an organization to monitor activities of employees, just something to think about next time you are looking online at work

  • Trojan:
  • Trojans are a type of virus that are designed to make a user think they are a safe program and run them. They may be programmed to steal personal and financial information.

  • Adware:
  • Adware is also known as advertising-supported software. It is software which renders advertisements for the purpose of generating revenue for its author.

  • Worms:
  • This type of malware will replicate itself and destroys information and files saved on the host PC.

  • Virus:
  • is a specific type of malware by itself. It is a contagious piece of code that infects the other software on the host system and spreads itself once it is run.

  • How did this get there??
  • The short answer is that malware can come from anywhere. To prevent it from getting on your computer though, there are things you can watch for.

  • An infected website:
  • A blog that you frequently go to could have some security holes in their setup. This has allowed someone to come in and insert code into the website. If a website says it needs to install something on your computer for you to view the website, such as Flash or Silverlight, I would go straight to www.adobe.com or www.microsoft.com to download the plugins. Don’t believe that the website will download flash for you, if could be anything.

  • Clicking Ads:
  • Sometimes a website will tell you that you have a virus on your computer! It scares you and you click to see what it is, or even to scan your computer… PLEASE DON’T!!! Usually these pop ups are nothing more than ads trying to force you to purchase their software. This “antivirus” software usually just installs more viruses on your computer, and can really mess it up.

  • E-mail Phishing Attacks:
  • Some of these attacks are really very believable, some are obvious. No, no one is giving out free iPads on Facebook. No, this is NOT you in this video. There is a video link, that is a virus with the title “is this you in this video?” or “I can’t believe you did this” for those that haven’t seen it, or better yet the PHONE call from Microsoft, asking you let them remote into your computer, like they offer a personal service like that!

  • Email attachments:
  • If you get an email from some you don’t know, with an attachment, or telling you, that a few million pounds is waiting for you once you have filled your bank details in and emailed it to the following Hotmail account, guess what, Delete it, don’t forward it to anyone, not even CILT.

  • USB devices:
  • Finding a free USB stick under your windshield wiper, or being handed out in the street isn’t always a nice gift, nothing is free and really isn’t worth plugging into your computer.
