Hello! Thank you so much for this forum and all your help. I have carefully read through the related threads, and I have tried to implement all your suggestions. Windows Defender detected the Zonebac. Further scans by Symantec Antivirus, Kaspersky (online), BitDefender (online), Spyware Terminator turned blanks. I enclose the relevant log files. Just to note, Panda Antirootkit detected no anomalies, and I forgot to save a report for the AVG Antispyware (so I took screenshots, one of which I attach -- only 39 minor traces were found in all). Also, noting from findAWF that Comodo, Symantec and Spyware Terminator were infected, I uninstalled all 3 and installed Outpost, Avast! and AVG in their place. Please could you let me know if I am now safe or what steps I need to take to solve the problems. Many, many thanks in advance.
