ClamAV vs Malwarebytes AdwCleaner

ClamAV is a free, open-source antivirus engine for email and web scanning and endpoint security tasks. It provides a multi-threaded daemon, a command-line scanner and a tool for automated virus database updates. The database receives updates multiple times per day, and the updater supports scripted updates and digital signatures. ClamAV scans standard mail formats and many archive, executable and document formats, including MS Office, HTML, RTF and PDF. A Milter interface supports Sendmail. On modern Linux versions, ClamOnAcc can scan files when accessed, with an option to block access until scanning finishes. Signed signature databases limit execution to trusted definitions. The project lists GNU/Linux, FreeBSD, macOS and Windows as regularly tested platforms, and official Docker images are available for Alpine Linux and Debian Linux. ClamAV is an engine and associated tools, not a traditional antivirus or endpoint security suite. Recommended minimum resources are 3 GiB RAM, a 2.0 GHz CPU and 5 GiB of free disk space. The project does not guarantee extraction of every version or variant of supported formats.

Malwarebytes AdwCleaner is a free Windows utility for detecting and removing adware, potentially unwanted programs and browser hijackers. It can also find unwanted software preinstalled on Windows computers. After scanning, you choose detections to quarantine and disable, then restart to finish cleanup; results also let you delete or restore items. The command-line interface can scan and list detections, scan and quarantine them, or uninstall AdwCleaner. Malwarebytes positions it for home users and technicians and distinguishes its focus from Malwarebytes Free, which also removes viruses, trojans, botnets and ransomware. Supported systems are Windows 11, Windows 10 and Windows 8.1; Windows XP, Vista, 7 and 8 are unsupported. Minimum requirements list an 800 MHz SSE2 CPU, 512 MB RAM and 10 MB free disk space. With a firewall, outbound port 443 access is required to three listed Malwarebytes or AdwCleaner service addresses. Suspected false positives can be submitted from scan results for specialist review. The Free plan is free.
