Final answer:
To prevent malware, Jose can use strong passwords and PINs, install anti-virus software, and enable two-factor authentication. He should also educate himself on common scams and hacking methods.
Step-by-step explanation:
Jose is right to take precautions against malware by avoiding suspicious email attachments and pop-up ads. However, he can enhance his computer's safety even further through several methods. Firstly, he should employ strong passwords and Personal Identification Numbers (PINs) that are difficult to guess which adds a layer of security in case his login details are targeted. Secondly, installing and regularly updating anti-virus software is critical. Anti-virus programs can detect and remove malware threats before they inflict damage.
Additionally, Jose should consider increased security measures such as two-factor authentication, which provides an additional security layer for online accounts beyond just the password. It's also imperative to educate oneself on the different scams and hacker tactics to avoid getting tricked into compromising personal or sensitive information.
