Antivirus software has a slightly different purpose. It does not help to make money, but it helps to keep the capital.
Indirectly, an antivirus can help keep money. The preservation of capital is carried out by banks and managers. The main purpose of the antivirus is to detect and block most of the malicious software.
I thins that antivirus is a very important and nessesary thing. Every user that use computers and mobile devices for paymants must use untiviruses.
