However, Avast has made headlines in recent years for selling user data and suffering cyberattacks. With about 435 million installations across Windows and Mac devices, it has been harvesting customer information via app and browser plugins from across the globe and transferring it to Jumpshot for selling client databases to companies, including Google and Microsoft, that want to target customers through sales ads. Avast has also become a victim of a cyber espionage web through which hackers have gained access to its network and client databases.
