Final answer:
To protect his computer from viruses, Martin should install anti-virus software and use complex passwords. He should also safeguard his personal and financial information by monitoring his accounts, securing his mailbox, protecting his wallet, and updating his contact information with the bank.
Step-by-step explanation:
Martin has concerns about keeping his new computer safe from viruses while surfing the web. To protect his computer, Martin should ensure that he has reliable anti-virus software installed which can prevent, detect, and remove malware. In addition, he should use passwords and PINs that are complex enough not to be easily guessed to secure any accounts he accesses on his computer. While these steps are essential for digital security, it's also important to protect personal information in other areas.
For securing financial information, Martin should protect his credit and debit cards from unauthorized use by monitoring accounts regularly and using secure payment methods. He should also protect his mailbox from identity theft by using a locked mailbox or a PO Box and should securely dispose of any sensitive mail. Protecting his wallet involves being cautious in public spaces and storing it in a secure location at home. Lastly, keeping personal contact information like his address or phone number up-to-date with his bank will help in preventing potential issues related to missed communications about suspicious activities.
