Each time you connect to the internet you take the risk that a virus penetrates your computer. Your personal information can be retrieved and sold to hackers, your searches are stored, you are polluted by pop-up ads and your computer becomes slower.

Here are  effective tips to protect yourself from these annoyances that pollute your computer:

The main types of malicious software

There are many types of malware, here is a list of the main categories:

Trojan and Backdoor

Their goal is to take control of your computer remotely by posing as a harmless file, via your downloads.

Spyware

It is a software that installs on your PC to retrieve personal information on your computer in order to transfer them. Spyware is divided into two main categories: AdWares and Keyloggers

Virus

This software reproduces on your computer and spreads to other files and programs on your computer.

Downloaders

Once installed on your computer this small program to look harmless will then download another much more aggressive virus.

Rogue

This program is a fake antivirus that offers you to clean your computer by making you download other programs that are other more malicious antiviruses.

The Wabbit

This virus does not infect your files, but it duplicates indefinitely on your computer to occupy all available space.

The Rookit

This software obtains the root privileges on a station, leaves a backdoor and erases its traces by deleting the log files
