ClamWin vs ClamAV
ClamWin is the same engine with ClamAV, but the different between ClamWin and ClamAV only the type of operating system. ClamWin use for Microsoft, and ClamAV use for Linux. Both engine use the same database update. So we can download the database update either at ClamWin.com or ClamAV.org to use for each engine.
How ClamWin Update the Database?
ClamWin antivirus can download the database by itself without user interference. We can schedule the engine to download at specific time. If we want to download the database to install to many computer, we can download it manually at http://www.clamav.net/download/cvd. The database for download divided into 2 files:
- main.cvd (update about every 3 months)
- daily.cvd (update everyday)
main.cvd is collection of some daily.cvd update, but this file only update every 2 or 3 months or after the daily.cvd file become to big to download everyday. That's why when we want to download, we can determine first when the release date of each update file. And we don't have to download all files if we already have the main.cvd at the same release date. Only daily.cvd that we have to download everyday, and this will not take so many bandwidth consumptions.
If we have a slow internet connection, we can download the ClainWin database update at near our location, because ClamWin is open source than this antivirus supported by many community, try to find the nearest location to download ClamWin database update at http://www.clamav.net/mirrors.html
ClamWin is a good antivirus, this software also can use as a portable antivirus, so we can use the ClamWin without have to install at Windows. Just copy the ClamWin files at USB Flashdisk or any other portable media, and run the exe file directly.

How ClamWin Scan for Virus?
We can directly scan drive by using right click of Explorer menu and run scan with ClamWin command. This software also can be schedule to scan all or several drive at Windows computer. Don't forget to setting the preference to move the infected files to specific folders (this folder only for virus). I installed this antivirus at my Windows 2003 server, and scan the fileserver drive at night after no user connected at server. We can set the email report if the ClamWin find virus.
The only thing that ClamWin can not do that this antivirus does not have a shield protection like any other commercial antivirus, but it's ok because this is opensource and free antivirus that can run so good at Windows 2003 server.
