Frequently Asked Questions

Is free antivirus software effective?

Free antivirus software from reputable vendors like Avast and AVG can be highly effective at protecting against malware. Independent testing confirms free antivirus tools often have excellent detection rates and features comparable to paid solutions. However, free products typically lack certain premium features like tech support and enhanced ransomware protection.

Do I still need antivirus if I have a firewall?

Yes, both antivirus and firewall software are still essential for comprehensive security. Firewalls help control network access but do not scan files or activity on your device for malware. Antivirus monitors system files, memory, and behavior to catch viruses, spyware, ransomware, and other threats that firewalls miss.

Is Windows Defender good enough as my only antivirus?

Windows Defender, the built-in antivirus for Windows PCs, provides decent protection but lags third-party options. Independent tests reveal Windows Defender has lower malware detection rates compared to top antivirus products. It may be suitable as a basic secondary layer of protection, but not as your sole antivirus tool.

Should I use more than one antivirus program?

Running two antivirus programs simultaneously is not recommended, as they can conflict with each other. Antivirus software works deepest at the system level, so having two can cause crashes, performance problems, false positives, and security holes if not configured properly. Use one robust antivirus program rather than trying to combine products.

How often should antivirus software be updated?

Antivirus programs should be updated as new threat definitions are released to keep protection current. Most antivirus tools update daily or even hourly as new malware signatures emerge. Enable automatic updates so your antivirus always has the latest signatures. You can also manually run updates to get instant protection against new threats.


Protecting your computer from the latest cyber threats requires running robust antivirus and firewall software from trusted vendors. Solutions like Avast Free Antivirus, Bitdefender Antivirus Plus, and Comodo Internet Security provide excellent free and paid options for individual components. Comprehensive security suites like Kaspersky Internet Security give you an all-in-one solution. Evaluate your specific needs and budget to determine the ideal antivirus and firewall products for your situation. With the proper protections in place, you can use your devices safely and securely.
