One careless click can cost your business more than just data — it can cost trust, reputation, and serious money.
That’s why choosing the best antivirus software isn’t just an IT decision. It’s a business-critical move, especially if you’re running a hybrid or remote startup.
Whether you’re working from a laptop in Singapore or spinning up virtual desktops in Sydney, one thing remains constant — your devices need protection.
But here’s the challenge: With so many antivirus programs out there (and dozens claiming to be the best), how do you choose the right one?
What to look for in antivirus software in 2025
The right antivirus solution should do more than just scan for malware. It needs to work in real time, adapt to new risks, and play nicely with how your team works — especially if you’re managing distributed employees across multiple countries and devices.
Here’s what to look for in a solid antivirus protection tool this year:
1. Real-time protection
You don’t have time to run manual scans every day. You need antivirus apps that detect and block threats as they happen — not after the damage is done.
Real-time protection is your first line of defense against ransomware, phishing, and zero-day attacks. Make sure your antivirus program includes this by default (some free antivirus tools don’t).
2. Malware protection that covers everything
From email attachments to drive-by downloads and shady browser extensions, malware can sneak in from anywhere. Look for a security software that:
- Detects known and unknown malware
- Includes web protection while browsing
- Scans USB drives and external devices
- Offers behavior-based detection, not just signature-based
3. Cross-platform support
Your team is probably using a mix of Windows, macOS, and even mobile devices. A good antivirus solution in 2025 should cover all platforms, without charging you separately for each one.
If your current setup only protects Windows PCs, it’s time to upgrade.
4. EDR vs antivirus — what’s the difference?
EDR (Endpoint Detection and Response) is different from traditional antivirus. EDR tools are more advanced and help detect suspicious activity across your devices, even before a file is flagged as malicious.
Think of it like this:
- Antivirus = basic lock on your door
- EDR = home surveillance with motion sensors
If your team handles sensitive customer data or operates in regulated industries, consider combining antivirus protection with EDR software.

5. Ease of use and automation
Let’s face it — most people won’t bother using software that feels like a chore.
You want an antivirus app that:
- Has a simple, clean dashboard
- Runs silently in the background
- Automates updates and scans
- Doesn’t slow down your system
If it takes more than a few clicks to configure, your employees probably won’t use it.
6. Low system impact
Antivirus shouldn’t feel like it’s eating up your RAM just to keep you safe. Choose a lightweight solution that works quietly behind the scenes. This is especially important for remote teams who may not have access to high-powered laptops.
Independent test labs like AV-Comparatives and AV-Test can help you compare how much different antivirus software impacts performance. These third-party software reviews are gold when making your decision.
7. Customer support and updates
Threats evolve. So should your antivirus.
Look for antivirus programs that offer:
- Regular virus definition updates
- 24/7 customer support
- Active development and threat research
And if you’re using party antivirus software that hasn’t been updated in a year — it’s time to move on.

Frequently asked questions (FAQs)
Do I really need antivirus software in 2025?
Yes, absolutely — even if you’re tech-savvy or using a Mac. Threats today go far beyond traditional viruses. Think ransomware, spyware, and phishing attempts. A good antivirus solution protects you in real time, stops suspicious behavior, and keeps your devices and data safe no matter where you’re working from.
What’s the difference between free antivirus and paid versions?
Free antivirus software usually offers basic protection like virus scanning and removal. It’s a great starting point but often lacks key features such as:
- Real-time protection
- Ransomware defense
- Secure VPNs
- Identity theft monitoring
- Customer support
Paid antivirus programs offer more robust security, regular updates, and additional tools for privacy and performance.
Is Microsoft Defender enough for Windows PCs?
Microsoft Defender has improved a lot and offers decent antivirus protection out of the box. It provides basic malware defense, firewall controls, and frequent updates. But if you’re handling sensitive business data, or want advanced malware protection and identity tools, pairing it with a third-party software might be a safer move.
Can antivirus software slow down my computer?
Some antivirus apps can be resource-heavy, especially older or poorly optimized ones. But most modern solutions are designed to be lightweight. Look for independent test results on system performance or choose tools known for minimal impact like Bitdefender or Sophos.
How do I disable antivirus temporarily?
Each antivirus program has its own process, but generally:
- Open the antivirus dashboard or settings menu
- Find the protection settings (often labeled “real-time protection”)
- Toggle off the shield or temporarily disable scanning
Make sure to re-enable protection after completing your task. Knowing how to disable anti virus is useful for troubleshooting — but do it with caution.
What is the difference between EDR and antivirus?
EDR (endpoint detection and response) is more advanced than traditional antivirus. While antivirus focuses on detecting and removing threats, EDR tools go further by monitoring endpoints for suspicious behavior, providing forensic insights, and responding automatically.
If you run a startup that handles a lot of sensitive data or you need detailed visibility over your devices, using both EDR and antivirus might be your best bet.

Cyber threats don’t wait — and neither should you. Whether you’re working from home, the office, or halfway across the world, having the right antivirus software in place is your first step toward protecting your business.
