✅ Correct Answer: Option 4 — Install software only from trusted websites.

The best method to avoid getting spyware on a computer is to install software only from trusted websites.

Spyware is a type of malicious software (malware) designed to secretly monitor a user’s activities and collect sensitive information without their knowledge or consent.

Spyware may collect information such as passwords, financial details, browsing history, and personal data.

A common way spyware infects computers is through software downloaded from suspicious or untrusted websites.

Therefore, downloading software only from official developer websites, verified application stores, and other reputable sources significantly reduces the risk of spyware infections.

Option 1: Install the latest operating system updates — Incorrect

Operating system updates are essential for maintaining computer security.

Updates often contain security patches that fix vulnerabilities attackers could exploit.

For example, Windows, macOS, and Linux distributions regularly receive updates addressing security weaknesses.

However, updating an operating system does not necessarily stop users from installing malicious software themselves.

A computer with the latest security updates could still become infected if the user deliberately installs spyware disguised as legitimate software.

Therefore, Option 1 is incorrect.

Option 2: Install the latest web browser updates — Incorrect

Updating web browsers helps protect computers against malicious websites, security vulnerabilities, and certain types of harmful downloads.

Browsers such as Google Chrome, Mozilla Firefox, and Microsoft Edge receive updates to improve security.

However, a fully updated browser cannot guarantee that every downloaded application is safe.

For example, an attacker might distribute spyware through a fake software download page. Even when using an updated browser, a user could download and execute the malicious installer.

Therefore, Option 2 is incorrect.

Option 3: Install the latest antivirus updates — Incorrect

Antivirus software is designed to identify, block, and remove malicious programs, including many forms of spyware.

Keeping antivirus software updated improves its ability to recognize newly discovered threats.

However, antivirus protection is not perfect.

Some new or sophisticated spyware variants may evade detection.

Additionally, antivirus software is primarily a security control that helps detect or block threats, while avoiding untrusted software downloads helps prevent exposure to a major infection source.

Antivirus updates are highly recommended, but they are not the best answer to this particular question.

Therefore, Option 3 is incorrect.

Option 4: Install software only from trusted websites — Correct

This is the correct answer.

One of the most effective ways to avoid spyware is to download and install software only from legitimate, trustworthy sources.

Attackers often hide spyware inside seemingly harmless applications, including free utilities, browser extensions, cracked software, and modified installation packages.

For example, a user searching for a free video editing program may find two download sources:

• Trusted source: The software developer’s official website.

• Untrusted source: An unknown website offering a modified or unofficial installer.

The official website generally presents a lower risk, while the unknown source may contain spyware or other malware.

Although even reputable sources cannot guarantee absolute safety, using verified download sources is a strong preventive measure.

Therefore, Option 4 is correct.

Understanding How Spyware Infects Computers

Spyware may enter a computer through several methods.

The most effective protection combines safe downloading practices with regular software updates and reputable security tools.

Best Practices for Preventing Spyware

1. Download software from trusted sources. Choose official vendor websites and verified application stores.

2. Keep your operating system updated. Install important security patches.

3. Update your web browser. Use a supported browser with current security protections.

4. Maintain antivirus protection. Keep malware detection software and its definitions updated.

5. Avoid suspicious links and attachments. Be cautious of unexpected emails and download prompts.

6. Review application permissions. Avoid giving software unnecessary access to sensitive information.

These measures work together as part of a defense-in-depth cybersecurity strategy.

Quick Comparison of All Options

Final Answer: Install software only from trusted websites.

✅ Final Selection: Option 4 — Install software only from trusted websites.

This practice reduces the risk of downloading spyware disguised as legitimate software.

Remember:

Spyware = Malware that secretly monitors users and collects information.

Trusted software sources = Official developer websites and verified application stores.

Prevention = Avoid suspicious downloads while keeping operating systems, browsers, and security software updated.

Therefore, the correct answer is Option 4 — Install software only from trusted websites.
