The functions of an antivirus

An antivirus is a program whose main purpose is the detection, blocking and elimination of viruses and other malicious codes. However, depending on the manufacturer, it can offer other very interesting additional services to keep the computer protected. Everyone knows that it is important to have an antivirus installed on your computer . However, we wanted to go one step further and, together with INTECO's Internet Security Office (OSI), we have learned what tasks it can perform to keep the equipment safe.

• Proper antivirus
• PC

one

Firewall function : It acts as a barrier between the computer and the Internet. It is used to control who accesses the information stored in the equipment and what information leaves it to the outside.

two

Analyze web addresses (URL's): Allows you to check if a web address links to a page that contains a virus or if, on the contrary, it is secure.

3

Email protection: A feature that analyzes incoming and outgoing emails to verify that they do not contain viruses. They usually include an anti-spam filter to prevent "spam" from sneaking into the inbox and an anti-phishing filter to detect attempts to impersonate trusted websites, banks, public administrations, prestigious companies, etc.-.

4

Backup copies : Function that allows you to make backup copies of the most important documents stored in the computer.

5

You might think that the more antivirus you have installed would be much better. However, this is a wrong assumption. Having one installed is enough. Of course, this must be updated at all times to detect the latest viruses that "circulate" on the Internet. Of little use to have installed an antivirus that has not been updated for a year since, for example, a virus created by a cybercriminal last week could be installed on the computer quietly without the antivirus or the user.

If you do not have an antivirus, we recommend that you buy or download a reliable one, for this reason we recommend that you visit the AVG website.

• There are many functionalities that they offer. Each one must select an antivirus and configure it correctly to take advantage of all the options they provide and thus protect the equipment as completely as possible. OSI offers users a free download section of free security tools, including antivirus.
