Broni,
I will probably (time allows) run Combofix.exe today. So far, I disabled/turned off all kind of malware shields, except Avast antivirus; will do it after I pull the Internet cable off (as I do not want to stay connected even for a short time between I turn Avast off and start Combofix. Or am I paranoid?). What about MalWareBytes? So far I haven't found "turn off" button. I have to go now, will check for your reply when I come back. So far I followed instructions for WINDOWS DEFENDER

* Click Start > Programs > Windows Defender or launch from the system tray icon.
* Click on Tools & Settings > Options.
* Under Real-time protection options, uncheck the "Real-time protection" check box.
* Click Save.
* Go to Start > Control Panel > Security > Windows Defender, at the bottom of the Window Defenders page uncheck under Administrator Options "use Windows Defender" and then Save.
* (When we are done, you can re-enable Defender using the same steps but this time place a check next to "Turn on real-time protection" check box.) ,
but I don't have "Real time protection" Option. Nor do I have "Windows defender under "Security". The only thing I see there is Firewall, which I turned down already. What should I do?
