Attaching the logs from ComboFix and zoek.
While Avast AV was disabled as instructed (and is now back on!), the Comodo firewall remained on and was very active as both programs did their thing. I hope this did not interfere with them; I allowed everything to run.
zoek has to be extracted from a zip file. The first attempt to install produced error messages, and when it did finally run there was an error. zoek instructed me to try again after a restart; this time, it worked.
Thanks again for your expert help.
