Synopsis: Clam Antivirus is a scanner for viruses and spyware. The virus/spyware database is constantly maintained by a group of volunteers, and the latest updates are always available for free. Note that the program does not contain an on-access real-time scanner. You must manually scan a file in order to detect malware.

ClamWin Portable is a portable wrapper for ClamWin. Alternately, instructions are available to make the official program portable.

To automatically update virus database periodically or during startup, see ClamWinPortableDBUpdate.
