A antivirus is a type of software created with the sole purpose of protecting the computer against most viruses, Trojans or unwanted invaders that put the integrity of the data that a computer always houses at risk, either by copying it without the will of the computer. holder, as by the infection that destroys or adulterates them. For instance: AVG Antivirus, McAfee, Avast! Antivirus.
Almost simultaneously with the development of computers there was the development of malware, stored programs that reproduce themselves as many times as possible and increase their population exponentially.
In the eighties the spread of PCs became massive and then the applications to detect and prevent these attacks (and especially their reproduction and massification) were perfected, in a race against the viruses that also did it.
Nowadays, however, the use of computers is already widespread enough that the effectiveness must be total: computers are used for transactions of large amounts of money, as well as to exchange really important information.
However, no prevention method virus is 100% safe, since malicious program developments find the vulnerabilities of these Software and exploit them for their destruction purpose.
Have a good antivirus seems essential in the daily use of computers, and many people underestimate its importance and then find themselves with the loss of a large part of its contents: antivirus have specific vaccines for tens of thousands of known virtual pests, and can make a comprehensive review system if they are installed at a certain time.
However, their work method it is much more effective if they are installed together with the computer, that is, if their action is always preventive. In the same way, it must be updated as many times as possible, to the extent that its power of action may become obsolete for some new threat.
Servers and secure networks
The techniques In terms of computer security, they were advancing very firmly throughout the development of computers, which is fundamentally explained by the fact that almost everything nowadays passes through the network: large companies could not function if a system was falls or if it is adulterated, as well as some fundamental state secrets for harmonious relations between countries are digitized.
Currently, a large part of the information is not found on computers but is accessed through them (or other equipment) but in reality it is on the Internet, in ‘Cloud’. The work of the security teams is even stronger, particularly in those of the network servers.
Have a active license Antivirus is just one part of a protection system that should be comprehensive, which should include minimizing user permissions, connecting only to known and safe Internet networks, transforming as many files as possible into the ‘read-only’ type avoiding possible transformations, and above all the permanent realization of backup of the data to physically place it in one place and stop having it only on the computer, much less on the network.
