Avast Free Antivirus vs Bitdefender Antivirus Plus

Avast Free Antivirus provides antivirus protection and is now part of the Avast One app. Its free protection detects, blocks, and removes malware, including viruses, adware, spyware, and Trojans, with real-time detection and PC scanning. Web Guard helps block scam websites, phishing links in email, and malicious downloads. On PC, File Shield scans files as they are added or opened, while Behavior Shield warns about suspicious app behavior. Mail Shield flags potentially malicious email attachments, and Ransomware Shield helps stop untrusted applications from changing or encrypting personal files. Network Inspector helps protect Wi-Fi networks from intruders; Firewall monitors traffic to help block malicious intrusions. Hack Alerts notify users if Avast detects that email passwords appeared in a leak or hack, while Avast Assistant offers guidance on whether online messages or offers may be scams. The free plan costs nothing for 1 device. Avast specifies Windows 7 or later and macOS 10.14 or later; automatic updates require internet access. Protection can continue indefinitely after activation, though the app may prompt for reactivation after 12 months.

Bitdefender Antivirus Plus Multiplatform protects Windows, macOS, iOS, and Android devices against malware, ransomware, scams, and other online threats. Real-time detection covers viruses, ransomware, zero-day exploits, rootkits, and spyware. Web protection blocks phishing and fake-shop sites, and layered ransomware protection safeguards documents, pictures, videos, and music from encryption. On Windows PCs, Vulnerability Assessment checks for outdated or vulnerable software, missing Windows security patches, and potentially unsafe settings.

The included basic VPN allows 200 MB of traffic per day per device; unlimited traffic requires adding Premium VPN.
