          “more” allows you to view files. And agreed, if used incorrectly, might cause extra CPU. Generally mistakes like this just become memory hogs.

            Thank you after reading the comments i am relieved: I had saved a 3 page fully worded .odt as as .fodt and opened it with a text editor; but then again all the files had been closed and i deleted the file in question a at least 30 mins before i noticed the process; regardless thank you

    more is a legitimate program (it reads a file and writes it out one page at a time), if it is the real more. It is a memory hog in that (unlike the more advanced pager less) it reads the entire file into memory.

    I did an experiment to see if I could get the real more to show similar fds to you. I piped yes "" | head -n10000 >/tmp/test, then ran more < /tmp/test 2>/dev/null. Then I ran ls -l /proc/`pidof more`/fd.

    Results:

    lr-x------ 1 andrew andrew 64 Nov  5 14:56 0 -> /tmp/test
lrwx------ 1 andrew andrew 64 Nov  5 14:56 1 -> /dev/pts/2
l-wx------ 1 andrew andrew 64 Nov  5 14:56 2 -> /dev/null
lrwx------ 1 andrew andrew 64 Nov  5 14:56 3 -> 'anon_inode:[signalfd]'

    I think this suggests your open files are probably consistent with the real more when errors are piped to /dev/null. Most likely, you were running something that called more to output something to you (or someone else logged in on a PTY) that had been written to /tmp/RG3tBlTNF8. Next time, you could find the parent of the more process, or look up what else is attached to the same PTS with the fuser command.

        A process can change its name. If I wanted to make sneaky malware for Linux, I’d have it call itself more or something innocuous too.

        The correct answer is “this is not enough information”. Why should a real more process eat ¼ of a core for any substantial amount of time?

          is there like a competent antivirus i could use: the system is freshly installed and i havent used any shady software; everything from the repo and a hash checked tor browser(I didnt visit any shady site just clearnet browsing)

            Then it’s probably just more. Again: your post did not contain enough information for anyone to provide an answer to your question.

            Antivirus doesn’t do what it promises. The only general solution for a compromised system is a clean reinstall. (This is true in Windows too.)

            There are several antivirus solutions for Linux, but you shouldn’t need them if you do not execute stuff you downloaded outside of your package manager. The maintainers of your distribution are supposed to check if their packages contain viruses.

    Yeah, next time don’t panic. Use ps and pstree and fuser (or the programs you like) to first find out the executable filename with full path and which program started it. Then you can kill it and you’ll have some info to start debugging things.

    Maybe? It could be numerous things. Are you using containers? Did an update or upgrade fail? Did you install and or patch something? Anything in sys logs giving off ERR or WARN? What’s your system and distro? What was the last few things you did before this popped?
