That’s exactly why reliable antivirus software is protection you shouldn’t go without.

For speed & system cleanup

If your PC is slow or packed with unnecessary files, this helps keep everything running smoothly.

FAQ

Do I still need antivirus software if I already use Windows Defender?

Windows Defender does a decent job on the basics, but it doesn’t cover everything. Most real-world problems today come from phishing links, sketchy websites, ransomware, and email tricks—areas where third-party antivirus solutions are typically much stronger. Think of Defender like a seatbelt; a full antivirus suite is like adding airbags, ABS, and a reliable collision warning system on top.

Do I need antivirus software if I have Windows 11?

Yes—Windows 11 can still benefit from additional antivirus software, because built-in protection often isn’t enough to keep up with today’s constantly evolving threats.

What’s the difference between Antivirus, Internet Security, and Ultimate?

Antivirus – basic protection against malware
Internet Security – everything in Antivirus + firewall + safer browsing + anti-phishing
Ultimate – everything in Internet Security + privacy tools + cleanup tools + VPN

If you’re unsure, Internet Security is the “safe middle ground” most people choose.

Does antivirus software protect against ransomware?

Yes—the products in this category include dedicated anti-ransomware features. They monitor your files and block attempts to encrypt them without your permission. Today, that’s one of the most important features to have.

Is the license annual or lifetime?

Most antivirus plans are annual subscriptions. Some also offer multi-year options. The exact term is always listed on the product page, so you know exactly what you’re getting.

Can I transfer my license to another device?

In most cases, yes. You simply deactivate it on the old device (or uninstall the software), then activate it on the new one. The activation guide walks you through it step by step.

Are updates installed automatically?

Yes. Antivirus tools update automatically in the background—new virus definitions, new protection rules, new threat intelligence. You don’t have to click anything or run manual scans unless you want to.

Do Mac, Android, and iOS devices need antivirus protection?

Mac: Yes. Macs are less targeted, but not immune—phishing attacks and adware are common.
Android: Definitely. Android apps and downloads are among today’s biggest malware sources.
iOS: iPhones don’t use classic antivirus, but security apps can still help with safer browsing, identity protection, and Wi-Fi security.
