Thanks for your explanation. You are, of course, correct, I should have told TDSSKiller to delete the file if I wanted to get rid of it. There are 3 options: 1) Skip, 2) copy to quarantine, and 3) delete. I guess I assumed that "copy to quarantine" would remove the file and put it into quarantine and allow me to restore it later if I wanted to; which I think is how most security programs work that I have dealt with. But I'm very glad I (accidentally) said "copy to quarantine" instead of "delete" since I later wanted to restore the file.
Thanks for the assistance your forum has given me with this. You have been very prompt and helpful.
I'll sign out on this subject now.
By the way, you have said that this conversation has been moved to the appropriate location. Can you tell me where? I'll go there next time I want to use the program-- to get the expert guidance you have suggested.
