Avast Threat Lab - Cryptomining behavior guidelines

Avast Antivirus protects your PC by detecting and blocking malicious behavior. To determine whether a website using cryptomining technology is malicious, we use a set of guidelines for acceptable behavior.

General guidelines:

• Websites show a text box with all relevant information.
• Websites do not mine before the site visitor grants it the right to mine by clicking on an Accept button.
• The Accept button from text box works as a direct mining referral.
• In case of changes in mining terms, a new text box with Accept and Decline buttons is shown.

Text box must be designed according to these rules:

• All information is fully visible, readable and understandable.
• Style is consistent for all information (reasonable size, logical position, color contrasting to background).
• Accept and Decline buttons are presented in the same style and color.

Information in the text box must contain the following information:

• Explanation of what mining is (this can be a link to more information)
• Notice that leaving the page will immediately stop the mining
• Notice of possible shortened battery life on the device
• Notice of increased electricity consumption and how this can affect the site visitor’s electricity bill
