Information security issues are increasingly facing not only organizations and complex systems (for example, banking security systems), but also ordinary users in their daily work in the Internet and using their smartphones.
The Internet is simply teeming with various viruses, which at a minimum will receive your personal information without your consent, or completely block the operation of your device.
How an ordinary user can protect youself against modern threats? - as one of the options - carefully read the manufacturer's instructions and follow them. Many instructions and manuals you can find on the website Guidessimo.com and others.
And most importantly, be careful and alert, do not download applications about which you know little, do not press the "OK" button, when you are asked to download an application, simply because it distracts you from the current activity and you want it to disappear faster.
Remember, your safety is in your hands.
