Just wanted to give an update. Cluelessly generated the same txt files from prior run as a 'save and run' and attached them (1st computer). Went back, deleted those files, then started where I was supposed to by downloading the FRST file, running, saving to same location on the second computer. Now going through the FRST Admin Fix scan. Seems to be taking a while (I don't know what a normal run time is like). Is there a point at which long becomes too long and I should stop and restart?
I apologize for the confusion on my end!
