- Malware is malicious software used to infect or access your computer, including viruses, trojans, spyware, ransomware and more.
- Fraudsters often pretend to be well-known organisations and ask you to click a malicious link or open an attachment. Your computer may be infected by following a link, downloading online attachments or opening an attachment in a phishing email.
- Once activated, malware can redirect you to bogus screens, and display prompts and warning messages designed to persuade you to enter security information.
- Ransomware can take control and encrypt your files and demand a ransom to release them and restore your data.
- Once infected, your device is likely to run slowly as the malicious software works to intercept data, particularly when you’re logging in to your online accounts.
