Some day there will surely be virus and trojans, because people happily load and install unsigned deb-files. It would be real easy currently to hack into several N900's. Fortunately Meego will have RPM-package format and unsigned RPM-packages are widely known as a shame on packager. Using dpkg to install programs, is almost always risky. (Only very very few DEB-files include a GPG signature.) Use apt-tools. http://talk.maemo.org/showthread.php...136#post578136
