6.1 Virus
A computer virus, like a flu virus, is specially designed to spread to certain technological devices and has the ability to replicate itself. It can cause unexpected or harmful effects, such as damaging system software by corrupting or destroying data.
How does a computer virus attack? For a virus to infect your computer, you must run the infected program that contains it, which in turn causes the virus code to run. This means that a virus can remain inactive on your computer. However, once the virus has infected your computer, it can steal passwords or data, send spam (such as links to additional malicious resources to your contacts), and even take over your computer. In fact, some viruses can damage both the hardware and the software of your device, and even have repercussions on any data connected to you (for example bank accounts, etc.)
How a virus can spread? Viruses can be spread via email and text message attachments, Internet file downloads, and social media scam links.
