Why antivirus still matters in the age of built-in security
In 2025, most devices come with built-in security. Windows has Defender, macOS uses Gatekeeper, and mobile systems like iOS and Android have sandboxing and app scanning. So it’s fair to ask: Do you really need antivirus software today?
Short answer? Yes, but with conditions. Let’s unpack what modern antivirus software actually does, why threats are evolving rapidly, and who benefits the most from having it.
What antivirus software really does in 2025
Forget what you knew about antivirus in the early 2000s. Modern antivirus software functions more like a cybersecurity suite than just a virus scanner.
Here’s what today’s leading antivirus tools actually offer:
-
Real-time scanning : Checks files and apps as you open or download them.
-
Threat detection and removal: Identifies, quarantines, and eliminates malware.
-
Firewall and web protection: Blocks phishing sites, suspicious downloads, and trackers.
-
Ransomware protection: Stops hackers from locking your data for ransom.
These features run silently in the background, giving you layered protection that your built-in software often lacks.

The evolving threat landscape in 2025
Cybercriminals are no longer amateurs. In 2025, many threats are powered by AI, making them smarter, faster, and harder to detect. Here are some of the biggest concerns:
-
Zero-day exploits: Malware that attacks unknown software flaws before they’re patched.
-
AI-generated phishing: Scams written so well they fool even tech-savvy users.
-
Ransomware-as-a-Service: Now available on the dark web, even non-coders can launch attacks.
Built-in protection tools are often slow to adapt. A robust antivirus suite gives you that extra shield you need in today’s fast-paced cyber battlefield.

Do you need antivirus on every device?
Not all devices are equal when it comes to cyber risk. Here’s a quick breakdown:
Windows PCs
Still the #1 target for malware. While Windows Defender has improved, many threats, especially ransomware, are better handled by a premium antivirus.
Mac users
macOS is more secure by design, but it’s not invincible. Trojans, adware, and fake apps targeting Macs are growing.
A lightweight antivirus can patch those gaps without affecting performance.
Smartphones
-
Android is vulnerable due to open app stores and sideloading.
-
iOS is more restricted, but phishing via SMS and email still happens.
Security apps can protect you from malicious links, fake login pages, and shady apps.
Smart home devices
Smart TVs, baby monitors, and doorbell cams are now targets too. While you can’t install antivirus on these directly, network-level antivirus tools can scan traffic and alert you of threats.

Free vs paid antivirus: What’s the real difference?
Free antivirus is better than nothing, but often lacks key protections:
-
No ransomware defense
-
No VPN or password manager
-
Ads and limited support
Paid antivirus suites provide:
-
Identity theft monitoring
-
Secure file shredding and cloud backup
-
Parental controls and multi-device protection
Think of it this way:
Free antivirus is a seatbelt. Paid antivirus is a seatbelt, airbag, and emergency braking system, all in one.
Who still really needs antivirus?
The short answer: almost everyone. But some groups should definitely not skip it:
-
Remote workers: Sensitive data, VPN usage, and multiple endpoints = high risk
-
Gamers: Need antivirus that protects without lag; some have “Game Mode”
-
Students: Easy targets for spyware and phishing
-
Parents:Need parental controls and safe content filters
-
Small businesses:Can’t afford data breaches or downtime
Even if you’re just browsing Netflix or checking email, a trusted antivirus helps you stay ahead of evolving threats.
Conclusion:
Built-in protections are helpfulb ut they’re not enough on their own. In 2025, cyber threats move faster than ever. Whether it’s a phishing email that looks legit or ransomware hiding in a browser extension, you need a second layer of defense.
A good antivirus:
-
Shields your files from encryption attacks
-
Warns you of sketchy websites or downloads
-
Gives peace of mind while you work, play, or stream
And for many users, especially families and remote workers, a paid antivirus is worth every cent.
