Frequently Asked Questions About Antivirus Software in 2025

Do I still need antivirus software in 2025?

Yes. Even though Windows, macOS, and Android devices include built-in security, they are not enough to stop advanced threats like ransomware, phishing, and spyware. The best antivirus software of 2025 offers real-time protection, identity security, and additional tools that go beyond basic malware detection.

Which antivirus is considered the best in 2025?

According to recent reviews, top antivirus choices in 2025 include Bitdefender for all-around protection, Surfshark Antivirus for budget-friendly security, ESET for lightweight performance, and Malwarebytes for malware removal. The best option depends on your device type, budget, and required features.

What’s the difference between free and paid antivirus software?

Free antivirus programs provide only basic virus and malware protection. Paid antivirus suites in 2025 include advanced features like VPNs, password managers, parental controls, cloud backup, and protection for multiple devices, giving you a more complete cybersecurity solution.

Will antivirus software slow down my computer?

Modern antivirus software in 2025 is optimized to run in the background with minimal impact on performance. Lightweight options like ESET are designed for speed, while a full system scan may temporarily use more resources. Scheduling scans during downtime prevents disruptions.

How often should I scan my computer with antivirus?

With real-time protection enabled, most users are safe for daily use. However, experts recommend running a full system scan at least once a month. Top antivirus software in 2025 allows you to schedule automatic scans for convenience and better security.

Can I install more than one antivirus program at the same time?

It’s not recommended. Running two antivirus programs simultaneously can cause system conflicts, slowdowns, and even reduce overall protection. Instead, choose one of the best antivirus suites of 2025 and rely on its built-in firewall and advanced security tools.

What is a firewall and do I still need one in 2025?

A firewall monitors your internet traffic and blocks unauthorized access. While Windows and macOS include basic firewalls, many of the best antivirus software packages in 2025 include enhanced firewalls for stronger defense against hackers and network attacks.
