Why does Canonical need to spend Twenty Minutes out of every hour Disabling our Browsers and Operating Systems while doing full scans of our Hard Drives?

Prove that there is any Legal 'just cause' for doing this./

What message to you receive, telling you that Canonical is doing this. Also please post terminal command of:

lsb_release -a

Can you expand on what you mean by "disabling" and what "scanning hard drives" actually involves.

In one of your other questions https://answers.launchpad.net/ubuntu/+source/ubuntu-docs/+question/640429 you have identified updatedb.mlocate as one of the processes that bring your system to the knees during their periodical run.
This cannot be the complete cause, because updatedb.mlocate should run just only once a day and not every hour.

I suggest that you re-employ the technique that helped identifying updatedb.mlocate as one of the programs that slow down your system and search for other ones.
You could then uninstall all the packages with io- and cpu-intensive operations that you do not need (mlocate might be one of them).

Has the problem with the hard disk already been resolved, or does dmesg still show plenty of errors like "ata1.00: failed command: READ DMA"?

You have been using Ubuntu for years. I have read your information on this question, and 640429. Could you give the specifications of your computer( Ram amount and exactly what kind)? Also, CPU speed. Also, do you have onboard video or separate video card? If so, how much ram does it take? I also use older computers, that work ok.

This question was expired because it remained in the 'Needs information' state without activity for the last 15 days.
