I modified Antivirus Scan with F-Prot-Servicemenü http://www.kde-look.org/content/show.php?content=107679
(FP-Linux-Workstation, Version 6.x, Engine 4.5.x. with command-line scanner fpscan) for Debian (squeeze) - KDE4-Desktop.
This is only the service-menu, you need to have F-Prot antivirus installed on your systemfolder /usr/local/f-prot.
TO INSTALL: extract the tarball and copy the file f-prot_virus_fpscan.desktop for Debian Squeeze into ~/.kde/share/kde4/services/Servicemenus, just for your user. Or install system-wide, example for Debian Squeeze, in /usr/share/kde4/services/Servicemenus, depending on your distro.
