You often hear computer users use the word “virus”. So what is this virus?
This term is used to describe machine code commands, that when inserted into computer memory can be done, copying itself into files and other programs on the computer.
If the hacker wants him to be able to cause serious problems in this way.
A virus is actually exploiting users, as it is in an easy term piece of software or order order that causes unwanted behavior in the computer operating system or application.
To protect your system, you must install and use credible software and ensure that you always delete all unknown mails you receive.
If there is any doubt about any software functionality, you must be careful and do not install the same. Always make sure you delete the email you received from an unfamiliar sender or random person, do not worry about opening this email you received because you can target your system to the virus. You should remember that adult websites are hacking paradise, so avoid them.
