While downloading the GNUStep files for Windows (
http://www.gnustep.org/experience/Windows.html), when I clicked on the "0.30.0" link beside GNUstep Core (http://ftpmain.gnustep.org/pub/gnustep/binaries/windows/gnustep-core-0.30.0-setup.exe), my Avast antivirus blocked the download. It detected the Win32:Evo Gen virus in gclose.exe.
