  • Works well with hMailServer.

  • Totally defective waste of time. All warnings and errors. "cannot connect-cannot find file on server- cannot download definition updates" etc.

  • It really lacks of a real-time file system scanner, but it runs flawlessy on a Pentium III 500 MHz system, 96MB and Windows 98. Just amazing!!

  • I'm not a Windows fan and I rarely use it. However, when I do, ClamWin is simply a must-have-installed-and updated. It's not without its flaws, but it's lightweight, has a minimalistic but functional interface, it does its job well, and doesn't stand on your way. Not to mention it's not a "black box", you can have full access on what it does and how (LGPL licence assures that). The lack of a "live" protection is probably the only thing that will keep some users away. However, as long as you scan what you download, you don't really need it. Highly recommended.
