Dark web scanning is the process of monitoring dark web websites. The dark web is often associated with illegal activities, such as cybercrime, data breaches, identity theft, the sale of stolen data, and more. Avast BreachGuard can automatically scan the dark web for your personal information that may have been part of a data leak or data breach. It can search through large databases of stolen usernames, passwords, Social Security numbers, and credit card numbers for sale. It’s important to regularly monitor your personal info to help prevent identity theft.
