Phishing and malware explained in brief

Criminals use phishing to attempt to gain access data from Internet users. To do so, they send e-mails with a falsified sender address, or call their victims, pretending to work for banks or software manufacturers. They use the data they obtain either for their own fraudulent purposes, or to sell to third parties.

Protect yourself against phishing by never reacting to suspicious e-mails, but simply deleting them.

Malware is the collective term for programs that cause damage. This includes viruses for example. If your computer is infected, the hacker can see and modify your data, and initiate credit transfers. Protect yourself against malware by using an up-to-date virus scanner at all times. You should also exercise care when dealing with suspicious e-mail attachments.
