Il y a quelque temps, Microsoft Defender a \u00e9t\u00e9 point\u00e9 du doigt pour son impact n\u00e9gatif sur les performances des PC sur lesquels il est install\u00e9. Apr\u00e8s une nouvelle enqu\u00eate en profondeur, TechPowerUp r\u00e9v\u00e8le qu\u2019un bug est \u00e0 l\u2019origine de ce ph\u00e9nom\u00e8ne et que seuls les processeurs Intel sont concern\u00e9s. Aucun correctif n\u2019est pr\u00e9vu pour le moment, mais une solution temporaire est disponible.<\/strong><\/p>\n

Cr\u00e9dit\u00a0: Microsoft<\/figcaption><\/figure>\n

Ces derniers mois, Microsoft Defender est au c\u0153ur d\u2019une petite pol\u00e9mique. Apr\u00e8s avoir \u00e9t\u00e9 sacr\u00e9 meilleur antivirus sur Windows\u00a010<\/a> par le site AV-Comparatives, ce dernier fait machine arri\u00e8re quelque temps apr\u00e8s en accusant le logiciel d\u2019impacter consid\u00e9rablement les performances des PC<\/strong>. Il serait m\u00eame l\u2019un des pires du march\u00e9 dans cette cat\u00e9gorie. Une bien mauvaise publicit\u00e9 pour l\u2019antivirus, pourtant largement appr\u00e9ci\u00e9 par les utilisateurs.<\/p>\n

Nos confr\u00e8res de TechPowerUp ont alors d\u00e9cid\u00e9 de mettre les choses au clair. En passant Microsoft Defender au microscope (ou plut\u00f4t, au benchmark), ceux-ci ont bien d\u00e9tect\u00e9 une forte baisse de performance lorsque l\u2019antivirus est actif. Test\u00e9 sur le processeur Intel Comet Lake-S Core\u00a0i9-10850K, le benchmark affiche une chute de 6\u00a0% des performances<\/strong>, un chiffre particuli\u00e8rement \u00e9lev\u00e9 pour un CPU de cette trempe.<\/p>\n
