Thanks ... I'll try this and report back here in a few weeks.or, move them into a folder, put that folder aside for a while (or on another drive), see how things go.but they do look like temp files from some app (usually, you find this sort of thing in the user preferences folder).
you can (sometimes) find these files in the user preferences folder; i have over years. seems just temp files, nothing complicated (or sinister).Looks less like temp files and more like a terminal command line gone wrong, as if something tried to eval a base64 string into your home folder instead of into a file.
Base64 evals are commonly used in obfuscated adware infecting websites - any chance you were working on Wordpress plugins or something?
