ClamWin is free, open source antivirus software for Microsoft Windows. It provides a graphical user interface to the Clam AntiVirus engine.

Features

  • Scanning scheduler (only effective with user logged in).
  • Automatic virus database updates on a regular basis.
  • Standalone virus-scanner.
  • Context menu integration for Windows Explorer.
  • Add-in for Microsoft Outlook.
  • A portable version that can be used from a USB flash drive.

Firefox extensions exist that allow the users to process downloaded files with ClamWin.[2]

Real-time scanning

ClamWin does not automatically scan files as they are read and written.

The non-affiliated project Clam Sentinel is an add-on that provides a real-time scanning capability to ClamWin.[3]

Updates

ClamWin has a virus database which is updated automatically when it detects connection to the Internet. A small balloon tip appears on the taskbar icon indicating completion status of the update process. A feature to be mentioned here is it retries tirelessly to establish connection with the server if it fails to download the updates first time.

Effectiveness

Historically ClamWin has suffered from poor detection rates and its scans have been slow and less effective than some other antivirus programs. For example, ClamWin failed to detect almost half of the trojan horses, password stealers, and other malware in AV-TEST's "zoo" of malware samples.[4][5]

In the 1–21 June 2008 test performed by Virus.gr, ClamWin version 0.93 detected 54.68% of all threats and ranked 37th out of 49 products tested; the best scored over 99%.[6]

In the 10 August-05 September 2009 test performed by Virus.gr, ClamWin version 0.95.2 detected 52.48% of all threats and ranked 43 out of 55 products tested; the best scored 98.89%.[7]

On 6 September 2011 cNet gave ClamWin a rating of excellent, 4 of 5 stars.[8]
