Common types of computer & mobile threat
Computer viruses are malicious software programs designed to infect and harm computers and networks. They can replicate themselves and spread from one computer to another, often without your knowledge. They're commonly transferred by email and are downloaded onto your computer by clicking on a scam link.
Computer worms are harmful programs that can copy themselves and spread on their own, without attaching to other files. They often take advantage of weaknesses in software or operating systems to move through networks. Worms can quickly spread through email, network connections, and instant messages, causing problems like slowing down systems, deleting files, and installing access points for future attacks.
Threats to the data on your mobile phone usually come from malicious apps that you or someone else has downloaded. Once installed they can steal personal information, financial data, and login credentials, display unwanted ads, slow down devices, or even take control of your device.
A trojan is a type of malicious software that disguises itself as a legitimate program to trick users into installing it. Once installed, a trojan can perform harmful actions, such as stealing data, spying on user activity, or creating backdoors for other malware to enter the system. They can often transmit confidential data even if you're not accessing that data at the time.
