Understanding Antivirus
As described above, the antivirus is a software program that identifies malware - popularly known as viruses. Antivirus can be used on computers, phones and tablets, and can monitor the behaviour of installed applications, which when they have some kind of suspicious action, have their activities blocked or moved to a quarantine.

During this quarantine, its performance is supervised in order to diagnose the possible causes of the problem. According to Consulting, a consultancy specializing in cyber worldwide attacks, e-mail is the most common device infection channel.

In practice, as soon as an antivirus is installed, it will scan all files on the computer, creating for each of them a "digital signature". This subscription will make periodic updates to verify that there has been no change to the files. If something strange is detected, the user is automatically notified, to follow the actions.

In addition, protection programs may be specific to a particular type of virus. Like, for example, Antispywares , which are focused on fighting Spywares and Adwares . These two types of viruses often contaminate browsers to steal bank details and display unwanted advertising banners.

It is important to note that before installing the antivirus on a computer, it is necessary to observe its specifications and evaluate the best option for each case. For example, an antivirus made for Windows will hardly be effective on an OS X computer, because each operating system has its own peculiarities.

Just like a version for home computers, it will not work on a company server. In this case, you will need to purchase a corporate version of the chosen solution.

The scanning of emails is an example of these additional, quite useful for companies.

Programs that usually crash
Operating system that is no longer responding as usual
