LS. The problem I met may not be new, but, to a lazy person like me, to sponge on the more knowledgeable is easier then searching the archives. So, on the assumption the problem is new, her goes. Recently I switched to SuSe 9.1 Linux for my internet work, assuming I would be safe from intruders. However, in the beginning my machine came up with SPAM-like "screensavers", offering Viagra, interesting pictures and a rigmarole about Jack working all day. As soon as I touched a key they disappeared, but immediately after that KDE, never lightning fast, reacted much slower. Logging out did not help; the computer had to be restarted. Recently (because I choose a "real" screensaver?) the problem stopped occurring. No harm done apparently. Nevertheless the situation is a bit disquieting; how can this happen? It does not seem likely that the "screensavers" were included in the software, if only because the purchased version is (almost) identical to the downloaded one. As I was physically connected to a server, they may have come from the outside, but how?? Is Linux leaky? A more practical question: "how can I solve the problem?" But then, maybe I already did. Ideas anyone? C.Huygen
