ClamAV vs Microsoft Quick Assist

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.

Microsoft Quick Assist lets someone get help with a computer problem from family or friends, or help them remotely. For a session, the helper generates a six-digit code; the person receiving help must allow the connection and screen sharing. The helper can use a laser pointer, annotations and chat, and can request control, which requires separate approval. The Windows app is installed from Microsoft Store for Windows 10 and 11. The macOS app is limited to Microsoft Support interactions, and the web app is only for verified Microsoft support agents. Both parties need internet access, and the helper signs in with a Microsoft account or Microsoft Entra ID. Quick Assist uses HTTPS over port 443 and TLS 1.2. Microsoft says it logs session times, errors and features used, cannot view session activity or keystrokes, and does not retain participant data longer than three days. File transfer and mobile apps are not supported. The free plan costs nothing.
