Mc Afee Antivirus signatures need to be updated regularly to ensure your computer is protected from new viruses.
Or after finishing the update you get a message "Your computer is at risk".
To install, double-click the Mc Afee file you have downloaded.
After a while you should receive a message that Mc Afee setup is complete (language will depend on system-configured languages). After a few moments, the agent will start downloading and installing Mc Afee Endpoint Security (except for Windows XP and Windows Server 2003, where the older Virus Scan Enterprise will be installed).
Hover with your cursor over the Scan option and a new menu will appear with types of scans that you can perform.
If you select the ' Custom' option from the menu the Custom Scan window will appear on your screen.
