Real-time scanning
ClamWin Free Antivirus scans on demand; it does not automatically scan files as they are read and written.
The non-affiliated projects Clam Sentinel and Winpooch are add-ons that provide a real-time scanning capability to ClamWin.
Updates
ClamWin Free Antivirus 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. It retries to establish connection with the server if it fails to download the updates first time.

Effectiveness
Historically ClamWin Free Antivirus has suffered from poor detection rates and its scans have been slow and less effective than some other antivirus programs. For example, in 2009 ClamWin Free Antivirus failed to detect almost half of the trojan horses, password stealers, and other malware in AV-TEST's "zoo" of malware samples.
In the 1-21 June 2008 test performed by Virus.gr, ClamWin Free Antivirus version 0.93 detected 54.68% of all threats and ranked 37th out of 49 products tested; the best scored over 99%.
In the 10 August-05 September 2009 test performed by Virus.gr, ClamWin Free Antivirus version 0.95.2 detected 52.48% of all threats and ranked 43 out of 55 products tested; the best scored 98.89%.
On 6 September 2011 cNet gave ClamWin Free Antivirus a rating of excellent, 4 of 5 stars.
