My questions are
- how do I detect a suspicious network connection?

Some background information regarding the above questions.
Firstly as some of you may have noticed I have very little to no
knowledge in this area.I am flat out running a business that is barely
paying bills and probably cannot afford to buy security software, hire
someone or spend much time on a computer security course.
I believe my computers are getting hacked.
If you computer is hacked then stop
there. Save your data, format
everything and reinstall your operating system. You are time poor so
that is the quickest option.
I have noticed files being changed/added in dropbox
that I definitely
hadn't changed/added myself.
There may be another explanation for this than
being hacked. Are you
using the Dropbox app or web interface? What are the files? Are they
found on both your computer and the cloud? When using the Dropbox folder
as an application data storage I have seen temporary files remain after
the application exits.
Also at times I am no longer able to easily change my
password or do
updates.Also I have noticed that at such times web browsing can become
very slow as well as the general speed of my computer.I am running
Linux Mint 18.My solution to computer security has been to change my
user password several times a day which seems to help.I do updates
regularly and use relatively low spec
Changing your password will be of no benefit
is someone has root access
to your computers.
computers (dual core machines) so that if there is a problem and
someone else is using my computer I can notice it more easily.I always
use regular hard drives so that any possible hacking cannot be done
too quickly.I have also written a program to change the hostname on my
computers and this seems to speed up my computers and web browsing for
a while.When web pages start malfunctioning,changing the user password
and computer hostname very often fixes it.
I have noticed that problems seem to be correlated with how many
network connections I see.I am thinking of writing a program to shut
down any suspicious network connections as long as I know how to
detect them.Buying security software may seem more cost effective but
I don't trust commercial products because the seller always has a
vested interest to encourage hacking etc to continue the sale of
products and maintain subscriptions.
I have been using Linux distributions on workstations and servers for
over 20 years. User accounts have been hacked in the past when users
insisted on using dictionary based passwords. Each time the give away
was the accounts were being used to send spam. A password reset stopped
that activity. No one has ever gained root access. I hope this helps
Unfortunately I have no computers that can run the latest Qubes Linux.
