When you open it, the virus is downloaded to your computer and then already doing their bad deeds. So if you are not sure from whom I received a letter, do not open anything. Vigilance – the main protection against fraud.

Members who have put the latest version of the software – are not affected. But those who ignore this requirement by software companies, may at any time be affected. Therefore, when you receive a push from macOS or iOS – do not ignore it. On Apple technology are also viruses and Apple quickly solve problems with them: your task – time to install all the updates.
