What is the “Joker” virus and how can it affect devices?
The malware infects victims by downloading some apps that appear safe and have good ratings, but are actually harmful to users.
Once the phone is infected with the Android operating system, “The Joker” displays the bank card data that the user has registered in the Play Store and other applications.
Thus, the Trojan is able to allow premium subscriptions in applications, until user accounts are emptied. In other ways, it can also display annoying ads, in the rest of the apps without the user’s permission.
When they can automate the mobile phone authorization for payment services without the user noticing, the credit card statement, at the end of the month, will have a fee so high that the phone owner won’t even recognize it.

Tatyana Shishkova, a cybersecurity specialist at Kaspersky, has presented a report outlining applications infected with “The Joker” that have already collected thousands of downloads around the world.
So if you have any of the following apps, remove it:
