There are many ways to protect our devices, there is no doubt that the most effective are antivirus, here we will explain how an antivirus works and more.
Antivirus, a tool to improve security on our devices
How does an antivirus work?
As is suspected, an antivirus has the main function of detecting possible threats and eliminating them from our electronic devices, such as computers and cell phones.
There is a varied amount of viruses such as the Trojan, to mention some and other types that can put the good and safe operation of the system at risk.
This type of program has the function of protecting, not allowing the theft of information and preventing malicious programs from entering our systems.
How does an antivirus work?: These rely on a database of signatures to identify the virus by comparing it with the registered ones, this does not allow the entry of viruses such as Trojan horses and others.
Now, if a virus that attacks our system is not registered in that database, it would not be detected by the antivirus. That is why there are several antivirus programs with different databases among them.
Currently, most antivirus have been improved and updated, not using the database as the main weapon. Now they rely on a system capable of identifying viruses that do not have a signature and do not appear in the databases.
To do this, what this system does is use a number of algorithms, which identify whether or not a file may or may not be an imminent threat.
This algorithm takes into consideration whether these potential threats can modify the registries or remotely connect to another device.
Hackers are always on the lookout
Steps to improve antivirus
It has already been seen in a simple way how antivirus basically work, however, many of them are sometimes not effective when doing their job and many do not have the ability to fully recognize viruses.
What must be considered?
The best and ideal when considering how to optimize the operation of the antivirus, is to be constantly aware of updating it.
In this way, it can be ensured that the database can effectively identify the most recent threats and that the new functions of the protective system that identify viruses without signatures are also incorporated.
On the other hand, it must always be taken into consideration that antivirus obtained for free, generally do not have all the functions. Many of them only have the function of identifying the virus, but they do not have the ability to eliminate it.
In that case, it is best to try to get the most complete one that can provide reliability and give some guarantee, based on the good testimonials of the users.
It is extremely important not to install more than one antivirus on our devices. This is due to the fact that a conflict between programs can be generated, given their possible incompatibility and thus affect the effective operation.
The important thing is always to have an antivirus since it is an essential tool. This will allow us to keep our systems out of harm's way, helping to combat potential threats to the security of our devices.
Updating is essential, it is known that on many occasions we are bothered by those constant "update available" notices and we ignore it.
