The news comes weeks after the WannaCry ransomware cyber attack hit the NHS and users in 150 countries. The malware produces false clicks from the infected systems to generate revenue from advertisements for the attackers.

The total spread of the malware campaign on Google Play (Google's official app store) may have reached between 8.5 and 36.5 million users, Check Point said on its blog.

The researchers had also identified other apps on the Google Play Store, which contained the malware, which were developed by other companies.

According to Tel Aviv-based cybersecurity company Check Point, the apps have been available in Google's Play Store for years, though the length of infection hasn't been determined. Notably, Google removed the malicious apps from the Google Play store after Check Point notified it about the threat.

Reviews - Most of the popular apps will have reviews by other users in the app store. Originally discovered by researchers at Check Point last week, the malware has been dubbed "Judy" and is potentially one of the most widely spread pieces of Android malware we've seen to date. Because it is unknown how long the malicious code existed in the apps, the true spread of the malware can't truly be known. The malware went unnoticed as the infected payload was downloaded externally from a non-Google server, after the installation of the applications.

The Judy Malware fiasco shows that even Google Play Store tends to pass up a major opportunity for malware on occasion, as it obviously did for this situation.
