I had the folder syswow64 popup on my PC when pressing keys on my keyboard.
Searching the net seems to reveal this might be quite a nasty virus but the removal process seems very involved and although I’m more computer literate than the average bear, this seems a bit beyond me.
Thank you for providing the logs.
Please do not change anything on the system for now.
Have patience and wait till I (or someone else) had a good look at logs.
