CAN WE TRUST ANTIVIRUS
There are a lot of free antivirus software and free versions of
commercial anti-malware. Can we really trust these free
Same question about commercial antivirus software. Maybe
they install back doors on our computers?
Very true. Maybe they do.
However, there are many people with technical experience
who are in a position to verify, either by monitoring for
unexpected outbound connections or by reviewing the code,
so we can be reasonably certain that they do not.
But think about the alternative: we know that malware installs
back doors, etc., so from a risk-based perspective, which one
would you prefer? A control that you personally haven't
investigated, but approved by many others, or a lack of control
that leaves you open to malware.
Pretty simple. Trust is not required, it is just up to you to
balance the risk factors for your circumstances.
If you need some guidance, large companies use desktop and
edge antivirus and antimalware, as well as antimalware on
laptops and other endpoints. It's not cheap for them, so it's a
risk-based decision to spend that money.
There is no more reason to expect that this software can get
in through the back door than any other software. Your
Internet browser could open a back door, your Word
processor could, and your computer hardware could.
Basically, you have to source your software and hardware
from vendors that you trust and trust based on their reputation
or from the review of many other users who have not yet
encountered a problem.
You cannot trust anyone. But you have to for example, when
you buy some food, you trust whoever produced it for not
putting poison in it. It would certainly be feasible; however, it
happens often enough to accept that risk, especially since the
alternatives have their own costs and risks (hunting wild
animals, foraging for berries, growing potatoes in your own
field, or simply starving).
Likewise, every time you install a piece of software, any piece
