6. Windows Security
If you use Windows 10, you already have a built-in antivirus, as well as additional protection modules, such as the SmartScreen filter, firewall, and user account control.
Core components of Windows Security
- Virus and threat protection — this section will show which antivirus is used for protection. This can be Windows Security or any third-party antivirus. Also, this section will display the results of the scan performed by the Windows Defender and a link to launch a third-party antivirus solution.
- Account protection — allows you to manage account security and log in. You can configure the Windows Hello service to set a PIN or biometric authorization (face recognition, fingerprint recognition) for a faster and safer login. Also available is the Dynamic Blocking feature.
- Device performance and health — this section will display information about the status of Windows updates, drivers, battery life, and storage capacity. Also, the Refresh Windows option will be available for performing a clean installation of Windows 10 with saving personal files and some system settings. This function will be required in case of problems of performance or stability.
- Firewall and network protection — this section provides Windows Firewall configuration information and links to troubleshoot network connectivity issues.
- Device security — offers overall security status as well as the management of advanced security features for your device. The available functions and options (such as Core Insulation) will depend on the hardware configuration of the specific device.
- App and browser control — here, users can configure the SmartScreen Filter for applications and browsers in order to protect themselves from malicious sites and downloads.
- Family options — Windows 10 has a set of parental control tools, and this section presents the information about their performance. Parents will be able to set computer usage limits, control the purchases of games and applications, as well as view the status and security status of a PC.
Many people ask whether the integrated Windows 10 antivirus is sufficient and how good it is. Although there might have been some problems with it several years ago, in 2019, the situation changed.
If in the previous year, the Windows Defender and Microsoft Security Essentials tests showed below-average virus and malware detection rates, the tests now demonstrate the maximum level of protection on Windows 10.
Does this mean that now you can turn down third-party antiviruses?
There is no clear answer. It will definitely be a great solution if you:
- Do not disable User Account Control in Windows, and perhaps do not even work under the Administrator account and understand why sometimes account control asks you to confirm actions and what the risks the confirmation may involve.
- Enable displaying the file extensions in the system and can easily distinguish an image file from the executable file, and the image file icon on the computer, flash drive or in the email.
- Check the downloaded program files in Virus Total, and if they are packaged in RAR, unpack and double-check.
- Do not download hacked programs and games, especially those where the installation instructions begin with “disable your antivirus.” Do not disable it.
How to select a free antivirus software
According to Symantec, about 400 thousand dangerous programs hit the Internet every day.
Worms, Trojans, spyware, blockers, viruses, exploits, and other types of such programs can not only affect the operation of your device but also subordinate it in order to solve their fraudulent schemes.
To reduce the risk of such problems, the developers of antivirus programs put a lot of effort in creating reliable protection for your computers.
For this purpose, they use various approaches to protect your computer from online attacks. All the products provide a similar set of features. What are some of them?
A good antivirus is required to provide the following functions:
- The antivirus monitor should constantly (in real-time) scan all those files, folders, and disks you are working with at any given time.
- The antivirus must contain a module that constantly monitors that the program code is not damaged.
- The antivirus program should have a scanner to check the suspicious folders on your computer and detect the virus in time, before any damage has been done.
- The antivirus should provide the ability to constantly update the virus databases: as they say, hackers are not asleep — new, more advanced, dangerous, and insidious viruses are constantly added to the well-known and familiar ones on the Web, and therefore your antivirus program must constantly replenish its knowledge base. The more often the database is updated, the better. Ideally, the virus database should be updated daily, automatically downloading updates from the remote server.
- It is highly desirable to have a special module that can create rescue boot drives: by booting from such a drive, you can check the system in a clean environment.
- For additional protection against network attacks, some antiviruses use a firewall.
- And, finally, the more intuitive the interface of the antivirus is, the simpler it is to install and configure. Ideally, the interface must clean and very easy to use.
What other aspects should you keep in mind?
- Many people are worried about how much the antivirus will affect the performance of their computer. Of course, any antivirus will use some system resources like HDD, memory, etc. As a result, they will slow down your PC. However, this will not make a big difference if you use a modern computer with a powerful processor, enough amount of RAM, and high-speed SSD.
- Not every antivirus software provides good results. Some of them are more efficient while others are less. If you care about your data protection, there are a lot of independent tests available online. Read them carefully and choose the most reliable solution.
- In order to make the right choice, remember your computer’s capabilities. Before installing an antivirus, you should carefully examine the system requirements that the developer specifies and relate to the capabilities of your computer like the processor, RAM, and the version of Windows you are using.
How to use your free antivirus efficiently
- Do not ignore the first scanning. When you install the software, it will ask you to make a full check. Do not ignore this, even if it takes several hours.
- Scan your computer periodically. Many antiviruses can do it automatically or have a schedule option. This will help you to detect any threats in time.
- Check archives before unpacking. Most viruses are packed into ZIP or RAR archives so it is a reasonable step to check them before unpacking.
- Check the internal drives, especially if it is not your own drive. This is a very easy way to infect your computer.
- Do not ignore the antivirus notifications. Pay attention to them as they can save your information and nerves.
- Regularly update the antivirus database. All the modern software updates them automatically but if you do not have a permanent Internet connection, do not forget to check the updates manually.
- Update the antivirus software regularly.
- Never install more than one antiviruses at the same time. Your computer will not work stable and they will highly load your system.
Antivirus software cannot be considered to offer 100% protection to your PC against external threats. Yes, they are becoming more powerful and reliable every year.
However, you need to understand that intruders will always be one step ahead. Therefore, along with antivirus programs, it is necessary to use system backup solutions.
Another disadvantage of using antiviruses is the heavy load on the processor and RAM. Of course, you can set the time for checking the file system when it does not interfere with everyday tasks on the PC.
Also, remember that an attentive user is the best antivirus protection of the computer.
If you plan to use a free antivirus, then go for AVG Antivirus since it has the most benefits and least problems.
