Antivirus, antimalware for Unix, Linux, Ubuntu, Android, etc.

Viruses multiply and survive when they find security holes in the basic software of a device.

In the Unix family, an open source operating system that is free for everyone, any developer can have access to the kernel, which is the fundamental nucleus that has the task of allowing communication between hardware and software, distributing information and executing orders.


At first glance, a free and accessible operating system might seem more attackable from anyone, but time has shown that there have been more developers who have helped solving gaps, rather than hackers eager to exploit system defects.

A developer becomes more famous when he discovers a gap in an operating system, compared to who writes a part of the software.

During several decades there have been very few cases of viruses that have found the possibility to act on Unix family systems, but they have already been solved for a long time.
The vast majority of internet servers all work with Unix family systems and have never had any infection problems.


Although some manufacturers recommend installing anti-virus on Unix and similar, there is a strong belief in the web that antivirus on these systems is not necessary.

On the other hand, when a Unix family operating system sends files to Windows, it may unintentionally transmit malicious files.
For this reason, when necessary, it would be advisable to use an antivirus to check the files beforehand, as a courtesy (or customer service) towards the recipient.

As we said, in the Unix family systems we should not be afraid of viruses, properly so-called, sneaky and invisible, but we must be careful not to be fooled by other malware that we can activate in a naive and involuntary manner.
