Let me be a bit more specific: from reading my log files and checking "all processes" through my system monitor, I have concluded that my computer has been turned into a zombie and probably added to a botnet.
I have learned about "nice" values (and it was "pulse audio" which had been set to a high value, one which is preceded by a negative symbol--"-11" in my case) and a variety of other things. I suggest that anyone who has been wondering about "poll_schedule_timeout", "futex_wait_queue_me" and "ep poll"shown for their processes read some of the discussions under "botnet" in the security area of these forums.
I plan to arrange for a clean install of Ubuntu for my computer (in other words, to have everything wiped off my disk and Ubuntu re-installed) and to learn more about securing my system before re-connecting that computer to the Internet. I also will change my IP address and see if my ISP can give me anything other than a static IP address.
I would appreciate additional suggestions for continuing my computer education. I am surprised that no one seems to have connected the "poll_schedule_timeout" problem with unauthorized use of computers, specifically with botnets.
