It’s really one of worst nightmares PC users can have when turning on their system and realizing it’s infected. Even today, most of computer users understand what virus is and how they can protect themselves, but a lot of people don’t know how the virus spreads. Viruses has been here for very long time. In the beginnings, they were spread with floppy disks. Sharing programs through floppy disks was very common in era before internet, so people used this to put viruses inside. Nowadays, most of viruses are spread through the use of internet. Before it could take days, but now hours or minutes to infect a system.

There are people who are doing really nasty stuff. They make little viruses that are embedded in pictures, videos and then they post link to all the social media sites, trust me one click on it is enough and your system is going to pop up on their screen. Then, they can control your entire PC. This is really scary, because they can turn on your web camera not knowing you are being spied, or monitoring your pc activity. They can even take all your passwords and see your credit card numbers when you are typing when ordering something, or transfer pictures, imagine all your private pictures seen by someone and this is just one of the ways you can be infected.
Don’t fall for a trap because viruses can disguise themselves very sneaky. When you sign in your email account it could look like you’ve got message from your friend with their name and address written. But it’s too late when you realize it’s actually a virus. Once a virus is in your system it will begin to perform some of the actions to attach to hard drive, system files or some other files by creating new copy of itself with file on hard drive.
