Hallo,
waere euch sehr dankbar, wenn noch mal jemand auf diese scan-ergebnisse schauen kann. trotz loeschen mit ccleaner, spybot und adaware scheint es immer noch malware zu geben. bin nach wie vor ratlos und leider nicht in der lage, jeden tag online zu gehen, sonst waere das problem wahrscheinlich schon behoben. derzeit zeigt sich als einzig uebrig gebliebene stoerung nur, das die Internetseiten wesentl laenger brauchen, bis sie geladen sind...

vielen dank im voraus!
