FAQs about antivirus software in 2025Do I need antivirus software in 2025?
Antivirus software remains essential for any internet-connected device in 2025. According to the AV-TEST Institute, over 500,000 new malware samples are registered each day. Built-in system tools can provide basic protection, but they may not offer the layered defence or advanced threat detection necessary to handle emerging cybersecurity threats.
Why it matters:
Over 500,000 new malware threats emerge daily (AV-TEST, 2025)
94% of data breaches begin with a phishing email (Verizon Data Breach Investigations Report, 2025)
Everyday users often report encountering threats through email attachments, downloads, or compromised sites

How does antivirus software work?
Antivirus software uses multiple detection techniques to identify and prevent malware infections:
Signature detection: Compares files against a database of known threats
Behavioural scanning: Detects suspicious actions like encryption, file tampering, or remote connections
Real-time monitoring: Continuously inspects system activity to block threats instantly
Scheduled scans: Allows users to check for dormant or deeply embedded malware
Modern antivirus tools are frequently updated and use AI to detect evolving threats.
Key insights about antivirus software
- Antivirus software remains essential in 2025 across all devices
- Free versions are suitable for basic needs; premium options deliver advanced protection
- Reputable labs and credible industry sources are critical for comparing products
- Threats are growing; continuous, real-time defence is now a necessity
Why real-time protection is essential
Real-time protection has become one of the most important features in modern antivirus software. Instead of waiting for scheduled scans, real-time monitors continuously evaluate files, downloads, and network activity for suspicious behaviour. This is especially critical in 2025, as threats like ransomware can encrypt an entire system in seconds. By blocking harmful actions the moment they begin, antivirus software significantly reduces the risk of system compromise and minimizes the damage of emerging or zero-day attacks.
Is there a difference between antivirus and internet security suites?
Yes. While antivirus software focuses on scanning and removing malicious software, internet security suites provide broader protection with features like:
Firewalls to block unauthorized access
VPNs for secure browsing
Spam and phishing filters to protect email accounts
Parental controls to manage online access for children
Security suites offer all-in-one digital protection for families, remote workers, and frequent internet users.

Will antivirus software slow down my computer?
Leading antivirus products today are designed to be resource-efficient. Independent lab evaluations (AV-Comparatives, 2025) show top tools use less than 2% of system resources during normal operation. Performance features include:
Gaming or silent modes to avoid interruptions
Startup and app optimization
Cloud-based scanning to reduce local impact
Is free antivirus software enough?
Free antivirus solutions offer basic scanning capabilities, suitable for low-risk browsing. However, many lack essential features such as:
Real-time threat blocking
Ransomware protection
Spam and phishing filters
Cross-platform coverage
Security analysts recommend premium suites for users handling sensitive data, working remotely, or using multiple devices.

Why antivirus matters more than ever
Cybersecurity threats have evolved far beyond traditional viruses, and modern attacks frequently combine phishing, social engineering, and automated malware designed to bypass basic system protections. This means that relying on built-in security alone is no longer enough, especially for users who shop online, work remotely, or store sensitive information on their devices. A reliable antivirus suite offers multiple layers of defence, from real-time scanning to advanced behavioural monitoring, ensuring that new threats are detected even before official virus definitions are updated.
How AI is powering the next wave of cyberattacks
Artificial intelligence is now a powerful tool for cybercriminals. According to the 2025 Bitdefender Cybersecurity Assessment, more than half of companies report an increase in phishing and ransomware attacks linked to AI, as attackers use generative tools to create convincing emails, fake identities, and automated scams. Data from the Hornetsecurity Cybersecurity Report 2025 shows that phishing emails have increased by 131%, underscoring that traditional filters are no longer enough — real-time antivirus software with AI-based detection is now essential for staying ahead of modern threats in 2025.

What features should I look for in antivirus software?
When choosing the best antivirus software, consider these core features:
Real-time scanning and automatic updates
Firewall and network security tools
Anti-phishing email protection
Cross-platform compatibility (Windows, macOS, Android, iOS)
User-friendly interface and customer support
Optional extras like VPNs, file shredders, or parental controls may also be important depending on your needs.
How does antivirus handle detected threats?
Antivirus programs typically offer these actions when a threat is identified:
Delete the threat if confirmed as malicious
Quarantine suspicious files in a secure folder for further review
Ignore (rare) only if confirmed to be a safe false positive
Most tools today automate this response in the background while alerting the user of any required actions.
