ClamAV vs Dr.Web CureIt!

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.

Dr.Web CureIt! is a Windows utility for scanning and curing malware on infected workstations. It is suited to on-demand checks rather than ongoing protection: the free version supports one-time scans, and the program does not provide real-time virus protection. A download includes current virus definitions, but there is no automatic update feature, so home users need to download it again for a current scan. The free version cannot select particular scan objects or use command-line parameters. Dr.Web CureIt! Pro adds selective scanning of files, folders, drives, virtual drives, network resources, and individual processes, plus command-line use in scripts and scheduled or automated IT systems. Pro also includes quarantine management with export, import, and cleaning. During free scans, the utility sends scanning statistics and system information to Doctor Web; the company says it does not transmit personal information that reveals identity. Sending statistics is optional in the paid version. The free plan is free for one-time scanning; the Pro plan is listed for five or ten days, with no price listed.
