Editors' Review

by   / September 18, 2014

ClamWin Portable is a fully functional, fully portable version of ClamWin Free Antivirus. Like the installed software, ClamWin Portable is capable of scanning all your drives for viruses and spyware, but it's not a primary antivirus solution. It's a fast, lightweight tool for spot-checking newly acquired files before transferring them to a USB drive and then to your PC. Since it runs on any compatible Windows PC without having to be installed or uninstalled, ClamWin Portable is ideally suited for the job.


Free, open source, compact: ClamWin Portable offers most of the advantages of the installed program, like being completely free (and ad-free) with the support of an open source project community. It doesn't take up much space on a portable drive, and it launches quickly.

Portable protection: You can run ClamWin Portable from your USB drive on host machines and scan files for infection before copying them to the drive.

Memory scan: ClamWin Portable also finds and zaps the nasty bugs that hide in system memory.


Manual only: ClamWin lacks an on-access real-time scanning capability. Files and folders must be scanned manually to detect viruses.

Slow on big scans: Lightweight ClamWin Portable performs well when scanning individual files and folders, but definition updates and larger system scans can take a long time. ClamWin Portable also lacked permission to open and scan many system directories.

Bottom Line

ClamWin Portable isn't the comprehensive antivirus solution your PC requires, but it's an excellent auxiliary tool for spot-checking files and folders for infection.
