Windows Defender; Υπήρξε μια εποχή που όλοι χρησιμοποιούσαν λογισμικό προστασίας από ιούς τρίτων κατασκευαστών και όχι της Microsoft, επειδή η εταιρεία δεν εστίαζε στην ανάπτυξη κάποιας προηγμένης εφαρμογής προστασίας.
But times have changed, and as you can see Windows 10 they now have a complex security system Windows Defender, soon to be called Microsoft Defender.

After its first release with Windows 8 as a native antivirus product running under Microsoft Security Essentials, Windows Defender has evolved relatively quickly. Eventually it became a fully-featured application that could persuade many not to pay for another third-party protection application.
Windows Defender is currently in Windows security suite in Windows 10, which includes many security tools that can be used by anyone, beginner or professional.
The Windows Security suite includes the following applications some of which are powered by Windows Defender:
Virus and threat protection
Account protection
Firewall and network protection
App and browser control
Device security
Device performance and health
Family options
Each of these functions has additional options. Virus protection for example, also has protection from ransomware, real-time protection but also various scanning functions.
Earlier this week, AV-TEST researchers released the results of a new round of testing of security applications for Windows 10.
The strange thing of course is not that Windows Defender is in top of the list, but the fact that it received the highest rating, just like the software from top security vendors like Kaspersky.
Windows Defender got 18 out of 18 points for protection, performance and usability.
Below we will see why Windows Defender can now be described as such a top product.

AV-TEST conducted two different series of tests in May and June and evaluated all products in three areas: protection, performance and usability.
Στην κατηγορία της προστασίας υπήρχαν δοκιμές που διερευνούσαν τον τρόπο αντιμετώπισης των ιών σε κακόβουλες 0day επιθέσεις μέσω του websites αλλά και μέσω ηλεκτρονικού ταχυδρομείου. Το Windows Defender κατάφερε να μπλοκάρει το 100% του maliciousυ software in both rounds of testing, exceeding the industry average (IA) of 97,1%.
AV-TEST then attempted to identify the most common malware detected over the past 4 weeks. Once again, Windows Defender managed to block 100% of the threats in both tests. The average was 99,8%.
Moving on to performance tests, things get a little more complicated as AV-TEST evaluates each product to determine how much it is "disrupting" system performance when running its security features.
Windows Defender was notable for the slowdown that occurs when popular startups websites με το λεγόμενο low και high hardware (αργοί και γρήγοροι υπολογιστές) με βαθμολογία 13% και 14%, αντίστοιχα. Αυτό σημαίνει ότι πήγε καλύτερα από τον μέσο όρο που είναι στα 19 και 16%, αντίστοιχα.
Windows Defender does not slow down the device when downloading applications, and the slowdown it produces reaches 8% when launching an application on both types of computers (low and high hardware) compared to an average of 10 and 9% respectively.
Windows Defender did not give false positives during usability tests, so it passed the tests comfortably.
