What mobile viruses "can do"
Viruses designed to infect mobile phones (on Android or iOS) are practically indistinguishable from computer viruses.
They allow attackers to launch malicious programs to:
- Intercept information about calls and conversations
- "Read" SMS correspondence
- Activate the microphone to record conversations
- Capture the surrounding situation using the camera
- Determine the location (track geolocation)
- Scan Bluetooth or Wi-Fi devices in the vicinity
- Collect information about visited websites
- Steal important personal data and account passwords
- Block the operation of certain programs or functions of the smartphone (or even the entire device) and demand a monetary "reward"
- Transmit all illegally obtained data to servers on the Internet

Types of mobile viruses
Among the main types of malicious software for smartphones, it is worth mentioning:
Spyware applications - collect personal information for further illegal use, monitor the user, or eavesdrop on them (some of them are practically "official" - they even have their own technical support or website)
Ransomware programs - block or encrypt important data and offer to return it to the user for a reward
Trojans - can deactivate certain programs, steal personal information, or even "block" the gadget (they "stick" to legal applications and infect the phone after installation and activation by the user)
Worms - can copy personal data, infect and "block" the phone, even "cooperate" with other viruses (they most often enter the device through SMS, MMS, or other digital media and are the most dangerous type of malware for Android, as they are programmed for infinite self-replication).

How to remove a virus from a smartphone
To clean your phone from malicious programs, experts recommend taking a series of steps:

- Download antivirus software - via Wi-Fi from the official app store.
- Scan the device with antivirus and remove all found malware.
- Remove the antivirus and restart the device.
- Download another (different) antivirus.
- Check the phone again (using another antivirus)
- Go to the phone settings and disable administrator rights for all programs and applications.
- Review all installed programs and delete those that you are not familiar with (the system will not allow you to delete what is really necessary for normal operation)
- An alternative way to "clean" the phone is to restore it to factory settings. Then all programs, except system ones, will be deleted.
