Malicious software - or malware for short - is considered to be the general term for all the potentially damaging computer software that hackers use to gain access and full control over victims’ systems.

This is done by taking advantage of vulnerabilities within these systems by using viruses, bots, trojan horses, spyware and more to disable, disrupt or take control of your computer systems. There are various forms in which malware comes, it can be as simple as being disguised as a useless file or even an intriguing app.

What are the different types of malware?

Worms - These generally use phishing attacks or vulnerabilities within software to spread. These worms only need to gain access to a small part of your system in order to quickly spread around the rest. In some cases they can gain access to a whole network and allow hackers the access to all files on held on there which can then be modified, deleted or stolen.

Viruses - These can be spread in multiple ways such as through a word document, infected website, email attachments or file sharing. Viruses feed off pre-existing infections within ones operating system and gain access to all applications. They then begin to send out viruses to other contacts in order to spread as much as possible. They are particularly difficult to deal with as they are able to replicate themselves multiple times within a system.

Trojan horses - These are a type of malware that disguises it self as a recognisable or legitimate file. Due to the fact that it appears harmless, victims will feel comfortable opening the file therefore allowing the malware to gain access to their operating systems. Once the malware is on your device, the hackers are able to spy on you or access your network. They can also steal, delete or change your data.

Spyware - Spyware gains access to operating system and then begins to spy on it. It collects data and records personal information such as addresses, credit card information and passwords. This form of malware is often found in free software protection systems found online. These appear to be helping you while harvesting your information in the background.

Adware - This is one of the most common forms of malware. This presents itself as pop up advertisements that may or may not have relevance to the viewer. These pop-ups often slow down your system and can install dangerous malware on your computer with just one click.

How can you identify malware on your device?

There are various signs that your device will show when infected by malware:

• An increase in adware pop-ups and other unrecognisable programs opening on your device
• Emails and instant messages are being sent out automatically without your knowledge
• The blue screen of death (BSOD)
• Device overheating
• Apps are excessively crashing
• Increased network data usage.

How can you deal with malware?

This is a question with an answer that changes every day. With the changes in technology and improved techniques, it is becoming increasingly difficult to protect ourselves. The removal of malware is a difficult and often dangerous procedure and the method changes depending on the type of malware being dealt with. The best way to protect yourself is to be cautious online and try to prevent the malware attack in the first place.
