As my laptop (Dell precision 16Gb, ubuntu 18.4) had been slower than usual, I had a look at top. Here I have a process, called frontend pegging 50% of the CPU.

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND     
 7189 root      20   0  111508  22584   7440 S  44.9  0.1   0:12.23 frontend

I have no clue of what it can be, and it is not a process started by my user as ps -uwhoami| grep frontend returned nothing. It is also there after restarting and kill 7189 asks me for superuser permission, reason why I do not think that a simple sudo kill would solve the issue. Though I have not tried yet.

Anyone has any help, suggestion, idea about what to do? Anyone heard about a virus that can cause that?

  • It may be related to an UEFI update I recently made: https://askubuntu.com/questions/1181159/cpu-running-much-harder-louder-after-software-update – SeF May 02 '20 at 15:39
