Sandmann,
vielleicht probierst Du einfach mal den STARTPAGE GUARD aus. Der wurde extra für die Lösung deines Problems geschaffen. Auf amerikanischen Privacy Sites wird das Progi immer sehr hochgelobt! Ich hab es zwar downgeloadet aber bisher noch nicht ausprobiert, weil ich momentan meine Ruhe vor solcherlei Unannehmlichkeiten habe. Das Programm erspart Dir einen Haufen mühseliger Experimente. Ist polnisches Produkt, aber gut. Erhältlich unter www.pjwalczek.com
BACKGROUND
Malicious programs (viruses, trojans, backdoors, etc.) sometime change the StartPage to "gain the ground". Spywares use this way to invade user's privacy by tracking destinations which user visited, and collecting personal information. In some cases this activity may be totally transparent to the user. But most often this is just plain annoyance when start page is changed without asking user's permission. SPG effectively deals with all this problems, making surfing the net safer, more secure, and by reducing frustaration - more fun.
