The text message will introduce the advantages of this software, such as recording and displaying the recipient's location. In particular, it will indicate that it is a free mobile phone software that can be installed without downloading.
Don't rush to install it. Check the properties of this Installer: the file size is 40 kb. Let's call this strange number again to see if "your number is blank". What do you think of this.
In fact, this is a mobile phone virus named "symbos/cabir". Once an attack occurs, the mobile phone sends a text message when it is okay, and automatically transmits the information of the host to others through Bluetooth. Cabir is a worm virus that is transmitted through Bluetooth. As long as you open and install the caribe file containing worms, the virus is activated and begins to search for new mobile phones through Bluetooth. If the virus is bad, it will not only affect your normal communication, but also make you pay for it because it will send messages automatically. If the number is too large, it will cost a dollar, that's a big deal.
Currently, the effective way to prevent such viruses is to set the Bluetooth mode of the mobile phone to "undiscoverable ".
