Kaspersky researchers discovered an increasing number of mobile applications bombarding users with unwanted ads caused by adware on Google Play store in the past three months.
Adware is among the most widespread threats for years. While not a virus, the monetization methods used in such software can pose a danger to users.
It enables the selling of user data relevant for targeting purposes to third parties and customized ads without permission, said Igor Golovin, a security expert at Kaspersky.
Some adware spread by accident. Legitimate applications can be prone to adware and they may still end up spreading unwanted ads inadvertently.
More often, this happens because of advertising software development kits (SDKs) and lack of testing an integrated advertising library, resulting in adware modules to sneak into the final code of applications.
To protect yourself from adware, Kaspersky recommends:
Prompt removal of an application that is acting unusually and displays unwanted ads.
Always check application permissions before installing the application to see what they can access and do on a device.
Use a reliable mobile security solution like Kaspersky Internet Security for Android which can help detect a variety of threats, including adware.
