ClamWin Portable is the popular ClamWin antivirus packaged as a portable app, so you can take your antivirus with you to scan files on the go. You can place it on your USB flash drive, iPod, portable hard drive or a CD and use it on any computer, without leaving any personal information behind.

Features:

ClamWin is a Free Antivirus for Microsoft Windows. It provides a graphical user interface to the Clam AntiVirus engine. It features:

* High detection rates for viruses and spyware
* Regular virus database updates. ClamAV team regularly updates virus databases to include a new virus/variant immediately after it appears
* Standalone Virus Scanner

Please note that ClamWin Free Antivirus does not include an on-access real-time scanner, that is, you need to manually scan a file in order to detect a virus or spyware. Also, ClamWin Portable has scheduled scans and updates disabled as they are not used in a portable scenario.
ClamWin is a simple, powerful and most importantly, free antivirus checker for Microsoft Windows.

The program features an easy to use GUI and the developers claim high detection rates for viruses and spyware although it doesn't seem to find anything extra or beyond what other anti-virus scanners find. The full program is facilitated by regular virus database updates so that's its generally always updated with the latest threats to your system. Unfortunately ClamWin Portable has scheduled scans and updates disabled so that the program is not locked in huge updates every time you activate it on the move. The downside of this of course is that it's never up to date with the latest threats. The big advantage of this version of course is that you can take it pretty much anywhere on a USB stick. However, the program does not feature a real-time scanner which means that scanning for protection is down to you. You have to manually scan your system with the program every so often to see if you have been infected with anything.
