ClamAV vs Dr.Web LiveDisk

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 LiveDisk is a free antivirus recovery tool for systems damaged by viruses or malware. It starts from a DVD or USB drive as emergency media, then launches the Dr.Web CureIt! scanner automatically. Users can choose a scan mode, run a quick scan or adjust scan settings. LiveDisk can remove viruses and suspicious files, restore infected items, and copy important data to external media or another computer. On startup it detects and mounts hard-drive partitions and establishes a network connection if possible. The included Midnight Commander file manager can search for and copy information, and the boot menu offers Memtest86+. Creating a USB drive requires at least 1 GB of free space; formatting is optional, and the creation application leaves existing files unchanged by default. USB booting requires BIOS support for a USB HDD device. Doctor Web advises checking that LiveDisk is current and updating its virus databases if needed, and lists 24/7 online technical support.
