ClamUI gives Linux users a free, modern GUI for scanning malware

ClamUI offers a free, modern interface for ClamAV on Linux, with profile scans, EICAR tests, and simple database updates.

ClamAV is one of the most popular antivirus solutions for Linux. While many Linux users consider antivirus unnecessary, the author of the ZDNet piece says they use ClamAV to make sure files shared with Windows users are virus-free. ClamUI simplifies this process by providing a contemporary interface for updating ClamAV's database, viewing logs, and running scans.

One of ClamUI's key features is profile-based scanning. Users can choose from a dropdown list that includes the home folder, a full scan, or a quick scan, and they can also manually select specific directories. Another useful option is the EICAR test, which uses harmless sample files to verify that the antivirus software and its database updates are working correctly; in ClamUI, the test can be run with a single click.

ClamUI is distributed as a Flatpak package. On distributions with Flatpak support built into the GUI app store, users can install it by searching for ClamUI. Otherwise, it can be installed via the command line, provided ClamAV is already installed. After launching the app, the first step is to update the ClamAV database from the Database tab, which requires the user's password. The log window then displays UPDATE COMPLETE.

To run a scan, users click the Scan tab, select a profile such as Home Folder, and click Start Scan. The process runs in the background with minimal resource use. In the ZDNet author's test, a scan of 412,695 files in the home directory took more than an hour and found one threat — an old EICAR test file that had been downloaded previously for testing purposes. The user can choose to quarantine, exclude, or copy the path of any detected file.

The main limitation noted in the article is that ClamUI, like ClamTK, does not support scheduled scans. Users who want automatic scans must set up a cron job using the ClamAV command-line interface. Overall, the author says ClamUI is easy to use, efficient, and preferable to ClamTK, and recommends trying it on a home folder or full system.
