Frequently Asked Questions
Do I really need antivirus software in 2026?
Yes, absolutely. While operating systems have built-in security, dedicated antivirus software provides significantly stronger protection. Cyber threats are more sophisticated than ever, with ransomware attacks increasing 150% year-over-year. Premium antivirus offers real-time protection, advanced threat detection, and additional security features that built-in solutions lack.
Is Windows Defender good enough?
Windows Defender has improved significantly and provides basic protection, but it consistently scores lower than premium antivirus in independent testing. Third-party solutions like Bitdefender and Norton offer better detection rates, ransomware protection, and additional features like VPN, password managers, and identity monitoring.
Will antivirus slow down my computer?
Modern antivirus software is designed to minimize performance impact. Top solutions like Bitdefender and Kaspersky score 6/6 for performance in AV-Test evaluations, meaning they have minimal effect on system speed. Full scans may temporarily slow your system, but they typically run in the background during idle times.
What’s the difference between free and paid antivirus?
Free antivirus provides basic malware detection but lacks advanced features like ransomware protection, VPN, password managers, identity monitoring, and premium customer support. Free versions often display ads and may not offer real-time protection. Paid versions provide comprehensive security and regular updates for emerging threats.
Can antivirus remove existing infections?
Yes, quality antivirus software can detect and remove most malware infections. However, some advanced threats like rootkits may require specialized removal tools. It’s best to install antivirus before infection occurs, as prevention is more effective than cleanup. Malwarebytes particularly excels at removing stubborn infections.
How often should antivirus scan my computer?
Most antivirus software runs real-time protection continuously. Schedule a full system scan weekly or monthly, depending on your internet usage. Quick scans can run daily. Modern antivirus typically runs scans automatically during idle periods to minimize disruption.
Does antivirus protect against phishing emails?
Yes, most premium antivirus includes anti-phishing protection that scans emails and blocks malicious links. However, you should still exercise caution with suspicious emails—antivirus is not a replacement for user awareness and good security practices.
Can I use antivirus on multiple devices?
Yes, most antivirus subscriptions cover multiple devices. Plans typically range from 1 device to unlimited, with family plans offering the best value. Check that your chosen antivirus supports all your platforms (Windows, Mac, iOS, Android).
