Think about how much valuable information is stored on your computer - from fairly innocuous information about you and your work to truly sensitive data (credit card passwords, financial documents, personal correspondence, etc.). Now imagine that your computer was hacked and all this information became available to strangers. Or an evil virus has destroyed half the contents of your hard drive, and you have lost your finished project, which is due in two days. Introduced? Did you like it? The worst thing is that these cases are not fiction at all. It is enough to neglect the simple rules of computer security a couple of times - and it will not be difficult for an attacker to gain access to all your information, and viruses will multiply on your computer one after another. Agree, you have something to lose - and something to protect. It is for those who want to protect their computer and themselves from unpleasant surprises that this book was written. With its help, you will learn to protect yourself from viruses and other malware, recognize and repel hacker attacks, the tricks of Internet scammers, and control access to those resources that your child should not visit.
