Thanks for your help so far. I would like to/must start again please Kevin.
At this point, after running FRST.exe and on getting to the end clicking on "fix" only elucidates a reply that everything should be in the same place; there is no "fix" so to speak. So it seems I need to return to the beginning.
I am operating in safe mode on the crashed desktop computer. My messages to you come from my laptop. I am running a USB from the laptop to the desktop computer to transfer information etc. I have done the tasks again [in safe mode] on the desktop computer and ask that you create another fixlist.txt file for me please; and tell me exactly how and where [i.e. so that all the files, including fixlist.txt, are together somewhere; and where that should be] to save it on the crashed desktop computer via USB.
I have not uninstalled EAM on the desktop computer yet as I do not understand how then I am going to run Emsisoft again after that, or do I somehow install another one on the desktop computer later; bearing in mind that I cannot access the internet on the desktop computer because of the Trojan? When do I uninstall EAM; before or after I paste in the new fixlist.txt file you send me? I do need an answer to these questions.
I have saved all/each of the relevant files you need again together [as attached] to identical folders on "C" Drive and on the "desktop" of the desktop computer. The folders are: "FRST", "EEK", and "Downloads". Is this appropriate?
I have been running Emsisoft and Kaspersky side-by-side on the desktop computer for many years without a problem; so I wonder that this has caused the infection now.
I am avoiding having the desktop computer turn off at this stage as I suspect it may never start again.
I look forward to your reply and answers to my questions,
