I did everything like you suggested and uninstalled Avast!. After that ComboFix ran smoothly and it seems I can access webpages again! I had a look at the ComboFix log and the ilividinstaller and searchqu .exes seem to have been caught. Is there anything else I should look into? System restore perhaps?
Again many many thanks, I don't know what I would have done without you guys, you really saved my day (night!
