La protection dans le domaine informatique est un param\u00e8tre d\u2019une importance capitale dans le monde virtuel. \u00c0 cause de tr\u00e8s nombreux dangers qui circulent sur internet et m\u00eame dans les supports de stockage tels que les cl\u00e9s USB, les disques durs et autres, il est important de poss\u00e9der les logiciels ad\u00e9quats. Par d\u00e9faut sur les ordinateurs Microsoft il existe l\u2019antivirus Windows Defender, mais est-il suffisant\u2009?<\/p>\n\n\n\n

Qu\u2019est-ce que c\u2019est que Windows Defender\u2009?<\/strong>
C\u2019est un antivirus automatiquement install\u00e9 sur votre syst\u00e8me d\u2019exploitation Microsoft. Celui-ci \u00e9tant pr\u00e9sent par d\u00e9faut, il assure donc la protection de votre PC contre la plupart des menaces virtuelles. Pr\u00e9sent sur toutes les versions de syst\u00e8me (Windows 7, 8, 10) elle est consid\u00e9r\u00e9e par beaucoup comme un v\u00e9ritable service de protection de votre machine. Mais, est-elle vraiment suffisante\u2009?<\/p>\n\n\n\n

Une d\u00e9tection lente et souvent absente<\/strong>
Il est important de savoir que comme tout logiciel, l\u2019antivirus Windows Defender lui aussi conna\u00eet de multiples \u00e9volutions technologiques. Les versions pr\u00e9c\u00e9dentes rencontraient de tr\u00e8s grandes difficult\u00e9s quant \u00e0 la d\u00e9tection d\u2019\u00e9l\u00e9ments dangereux. En effet, jusqu\u2019ici, celui-ci n\u2019\u00e9tait particuli\u00e8rement efficace que d\u2019une mani\u00e8re p\u00e9riodique et donc avait de la peine \u00e0 d\u00e9tecter certains virus comme les ransomware<\/a>. Contrairement \u00e0 des antivirus tels que Avast<\/a> qui lui, depuis longtemps poss\u00e8de des syst\u00e8mes d\u2019analyse bas\u00e9e sur des crit\u00e8res comme la signature ou la d\u00e9tection comportementale pour reconna\u00eetre des fichiers potentiellement dangereux, Windows Defender r\u00e9alise une analyse g\u00e9n\u00e9rale parfois invisible. <\/p>\n\n\n\n

Une mise en quarantaine moins efficace<\/strong>
Avast antivirus<\/a> poss\u00e8de, dans le monde de la s\u00e9curit\u00e9, l\u2019un des syst\u00e8mes de mise en quarantaine virale le plus puissant et le plus d\u00e9velopp\u00e9 qui soit. Tr\u00e8s efficace, il donne la possibilit\u00e9 d\u2019emp\u00eacher un virus, quelle que soit sa puissance de nuire \u00e0 votre syst\u00e8me d\u2019exploitation.
Windows Defender, par contre, ne dispose pas d\u2019un tel syst\u00e8me. Il s\u2019agit plut\u00f4t d\u2019un syst\u00e8me d\u2019alerte qui n\u2019intervient pas automatiquement sur les virus d\u00e9tect\u00e9s mais qui vous alerte pour que vous g\u00e9riez vous-m\u00eame la menace. <\/p>\n\n\n\n

Windows Defender : Un taux de d\u00e9tection bien plus faible qu\u2019Avast<\/strong>
Alors qu\u2019Avast a \u00e9t\u00e9 \u00e9lu meilleur antivirus de l\u2019ann\u00e9e par AV-Comparative<\/a>, notamment gr\u00e2ce \u00e0 ces tr\u00e8s bonnes performances en terme de d\u00e9tection des virus, Windows Defender reste l\u2019un des antivirus avec le plus faible taux de d\u00e9tection de virus dans les diff\u00e9rents tests r\u00e9alis\u00e9s par AV-Comparatives et AV-Test.<\/p>\n\n\n\n

Ainsi, on peut donc constater que depuis des ann\u00e9es les programmes antivirus par d\u00e9faut de Microsoft n\u2019ont pas \u00e9t\u00e9 capables d\u2019assurer pleinement la protection de votre PC. C\u2019est pour cette raison que les antivirus comme Avast ont connu un tr\u00e8s fort d\u00e9veloppement.<\/p>\n","protected":false},"excerpt":{"rendered":"
