The term malicious software, or Malware as is more commonly known, is a piece of software that a hacker will create with the intent to harm users data, networks and even people.
Malware has many different types that are all designed to do different things. Examples of this include Spyware, Adware, Trojans and Viruses.
Malware can damage a system or network in many different ways that can be easily categorized into a list for you.
Virus: Just like a virus’ we get when we get them, a virus will attach itself onto A clean file and spread to infect other clean files in the system. These can spread very quickly and uncontrollably, damaging files or even deleting them.
Trojans: Trojans get their name from a story in ancient greece where soldiers hid inside a giant horse, crept out at night and attacked the city. This is how this piece of malware works. It looks like a legitimate software that opens a backdoor in you security to let other malware in.
Spyware: We won't be surprised if you guessed this one already. Spyware is designed to spy on your browsing habits and steals passwords, credit card numbers and takes notes on everything you type on your keyboard.
Worms: Worms can attack entire networks of devices. This happens when one computer is infected a worm can spread through the local internet and infect any other device that is also connected to the same network.
Ransomware/ Scareware: This form of malware can lock your entire PC and will threaten to delete everything unless the victim pays a ransom to the hacker.
Adware: although they are not directly malicious, adware is an aggressive form of advertising software that shows you a large amount of ad pop ups. These pop ups can occasionally contain other forms of malware.
Botnet: This form of malware are a network of infected computers that work together under the control of the hacker to do whatever they wish.
Each form of malware can infect your system in different ways. The best way to avoid getting infected is by using real-time protection and also changing your browsing habits. Start by not clicking on advert pop ups, avoid suspicious looking emails, links and websites.
If you see an ad that interests you, search for the company that is supposedly advertising and go to their official website. As for suspicious emails and links if you ever received a random link it is best to assume it is a virus until proven otherwise to stay the safest.
