ClamWin is a free and open source antivirus utility for Windows-based systems. Users are provided with a graphical user interface to the ClamAV engine. This software scans on demand, that is you are enabled to manually scan and remove infected files from your computer.

When the software detects a connection to the Internet, it automatically updates its virus database. On the taskbar icon, a Small balloon will appear, indicating the completion status of the update process. If the updates are not downloaded when it connects to the internet, it retries to establish a connection with the server.

Why you should use ClamWin

ClamWin is compatible with different Windows versions, like Windows 98, Windows ME, Windows 2000, Windows XP, Windows Vista, Windows 7, Windows Server 2003 and Windows 2008. This means that the system can be run on almost every PC, even ancient systems that other antivirus protection vendors often times ignore.

The developers concentrated on the bare essentials as ClamWin does not have too many unique features. What you can do with this antivirus freeware, is to use it as a second opinion scanner so if your regular antivirus fails to detect a threat, even when you perceive it to be on your system, you can always scan your PC again with ClamWin to get a second opinion on the health of a particular file, folder, or the entire system. The antivirus software has high detection rates for viruses and spyware, so none attacks your system without your notice.

On the main window of ClamWin, you are allowed to select a location to scan, as well as being offered access to update the utility for the latest virus definitions, quickly. The scanning process is fast but requires a moderate amount of your computer's resources, so an older system may get very much stressed. ClamWin also takes care of your email client as well, checking for threats in incoming messages. There are other tools in the settings menu including dedicated tools for internet updates, proxy servers, scheduled scans, and email scanning and report.
