Device Lockers

Dr.Web protects your device from ransomware. These programs may be extremely harmful for Android smart phones and tablets. They can encrypt files located in the built-in memory or on your removable media (such as an SD card). The malicious programs can lock the device screen and display a ransom demand for decrypting and unlocking the device.

Ransomware can compromise your photos, videos and documents. In addition, the programs steal and transmit to the cybercriminals’ servers various information about the infected device (including IMEI), information from the infected device’s phone book (contact names, phone numbers and email addresses). Ransomware programs monitor incoming and outgoing communications and can block those communications if desired. All the information collected, including phone call data, is also transmitted to the control server.

Dr.Web detects and removes ransomware when they are attempting to get on your device. However, the number of malicious programs increases every day. That is why, it is extremely important to update Dr.Web virus databases on your device regularly, as it may prevent your device from getting infected.

If your mobile device is locked by a ransomware program and SpIDer Guard is enabled on it, you can unlock your device.
