What is antivirus software?

Antivirus software protects computers, smartphones and tablets against malicious software. Solutions range from free products to paid platforms with more extensive features. Every device should have current protection that matches the way it is used.

How does antivirus protect devices?

Antivirus software can:

• monitor files in real time and block, quarantine or remove malicious files before they infect the device;
• scan files already stored on the device and disable suspicious programs;
• inspect outgoing files and connections to help prevent the device from being used in another attack;
• use signatures and databases to detect known malware;
• use heuristic analysis to identify previously unknown threats.

Keep the antivirus application and its malware definitions up to date. After an update, run a scan when appropriate.

Does antivirus protect against phishing?

Phishing relies mainly on social engineering and human emotions. A criminal needs only a moment of reduced attention, a convincing pretext and a sense of urgency to persuade someone to click a link or open an attachment. The destination may imitate a bank, company platform, online store or social network so closely that even an experienced user can miss the difference.

An antivirus product with anti-phishing features can warn about suspicious links or domains, but it cannot fully protect a person or a company from manipulation. Technology supports protection; it does not replace awareness and careful verification.

The strongest weapon is education, awareness and technology

Reduce the risk by checking every suspicious message:

• Sender: inspect the complete address and domain, including small spelling differences.
• Subject: be cautious when it creates urgency or uses unusual language.
• Links: hover over them before clicking and verify the destination.
• Content: look for errors, threats, pressure and signs of automatic translation.
• Attachments: do not open executable files such as EXE, DLL, BAT, SCR or COM without independent verification. Be careful with documents that may contain macros.

HTTPS encrypts the connection but does not prove that a website is legitimate. Use a reputation-checking service where appropriate and combine security tools with regular employee education and realistic phishing simulations.
