Disguised as a harmless Wi-Fi service, the hidden malware RottenSys comes pre-installed with millions of Android devices. During tests, a team from Check Point Research discovered that the service is a next-generation spyware that floods devices with ads. To achieve this, the malware requests system permissions to silently download additional components then used to display advertisements and to generate fraudulent ad-revenues. Based on information provided by Checkpoint Research, Ashampoo RottenSys Checker quickly scans your device and lists all malicious software packages. The malware can then be completely removed with a simple tap.
