Antivirus, antimalware for Windows

The main reason why viruses have begun to multiply and survive is due to the technical structure of windows and its security gaps.
Viruses were born and raised using the windows operating system design errors.

 


Windows being a proprietary system, its source is not available outside of Microsoft and it is studied by a limited number of developers.
The feature of the closed system, which offers Windows a strong commercial advantage, prevents other experienced developers from studying, finding bugs and suggesting changes that can improve the operating system.

Over the years, however, even Windows has solved many of its problems and has become more secure than once.

To rest assured, you can use Microsoft Security Essentials (for older versions of Windows) or Windows Defender (for Windows 8 and Windows 10), all provided free by Microsoft.
This antivirus is free, easy to install, has the advantage of not slowing down the computer and is able to protect rather well.

 


In case you want to install a paid antivirus, there are many valid ones (Norton, McAfee, Kaspersky, Avast, G Data, Panda, etc.)

With any antivirus on the market remember that you can always be attacked, for example when the malicious code is brand new, when you run certain programs (.exe) imported for example by mail or USB memory.

Some very important rules to keep in mind:
Never open unknown executable files.
Never insert other people's USB memories on computers that contain important data without antivirus.
Never open mail attachments without checking the content, sometimes an address might seem familiar, but be a phishing.

During daily work, if you use a user with limited permissions, it is a method that guarantees very high security.
