Vous trouvez que votre smartphone Android agit de fa\u00e7on \u00e9trange ? Des pop-up et des pubs apparaissent sur votre \u00e9cran d’accueil ? Des applis se sont install\u00e9es \u00e0 votre insu ? Un virus ou un trojan s’est peut-\u00eatre immisc\u00e9 dans votre vie priv\u00e9e mais pas de panique, il est encore temps d’y rem\u00e9dier !<\/p>\n

<\/p>\n

Identifier le virus<\/span><\/h2>\n

Depuis quand votre smartphone est devenu fou ? En g\u00e9n\u00e9ral, les probl\u00e8mes co\u00efncident avec l’installation d’une application tierces. Faites un rapide tour des derni\u00e8res applis install\u00e9es et effacez-les. Il est possible que le bouton \u00ab\u00a0d\u00e9sinstaller\u00a0\u00bb soit gris\u00e9 si l’appli s’est donn\u00e9e les droits administrateurs<\/strong>.<\/p>\n

Si vous n’avez pas encore install\u00e9 d’antivirus<\/a>, faites-le d’urgence ! Vous en trouverez des gratuits et des payants sur le PlayStore. Et lancez un nettoyage depuis l’application antivirus que vous venez d’installer. Comme sur un ordinateur Windows, elle identifiera probablement le trojan ou virus. Elle pourra probablement l’\u00e9liminer, sauf si le trojan s’est attribu\u00e9 les droits d’administrateur. Il faudra alors employer la m\u00e9thode forte.<\/p>\n

Supprimer le virus<\/span><\/h2>\n

Vous n’avez pas r\u00e9ussi \u00e0 identifier le virus ? Restaurez votre smartphone Android<\/a> pour repartir du bon pied. Vous pouvez d’ailleurs opter pour le mode recovery<\/a> afin de r\u00e9initialiser les param\u00e8tres d’usine. Une m\u00e9thode radicale. N’oubliez pas de sauvegarder toutes les donn\u00e9es sensibles. Profitez-en pour mettre \u00e0 jour<\/a> vers Android Pie<\/a> ou la derni\u00e8re version disponible pour votre smartphone. Les mises \u00e0 jour corrigent les failles de s\u00e9curit\u00e9 d\u00e9tect\u00e9es.<\/p>\n

Vous avez trouv\u00e9 le fautif, il est temps de passer \u00e0 l’action ! Votre antivirus a bien identifi\u00e9 la faille mais n’arrive pas \u00e0 s’en d\u00e9barrasser ? Vous ne parvenez pas \u00e0 le d\u00e9sinstaller ? Faites un tour du c\u00f4t\u00e9 des droits d’administrateur : Param\u00e8tres<\/strong> > Param\u00e8tres avanc\u00e9s<\/strong> > S\u00e9curit\u00e9<\/strong> > Administrateurs de l’appareil<\/strong>.<\/p>\n

\"administrateur<\/p>\n

Ainsi, vous voyez appara\u00eetre toutes les applis dot\u00e9es des droits d’administrateur. Vous pouvez donc modifier les autorisations. Cela vous permet ensuite de supprimer manuellement l’application intrusive.<\/p>\n

Eviter les virus\u00a0<\/span><\/h2>\n

Installez un antivirus<\/strong> ! C’est indispensable sur un smartphone Android qui est un OS ouvert. Nous vous conseillons de ne pas installer d’applications tierces, en dehors du Google Play Store. Google ne peut pas les v\u00e9rifier et vous prenez le risque d’installer un logiciel malveillant.<\/p>\n

N’h\u00e9sitez pas \u00e0 v\u00e9rifier les demandes d’autorisation<\/strong> des applis que vous installez. En effet, pourquoi une appli photo devrait avoir acc\u00e8s \u00e0 vos contacts ? Vous \u00eates confront\u00e9s \u00e0 de nombreux exemples de la sorte, soyez vigilants et limitez les autorisations au strict n\u00e9cessaire.<\/p>\n

Vous avez \u00e9t\u00e9 infect\u00e9 et vous vous \u00eates d\u00e9barrass\u00e9s de la menace ? Nous recommandons tout de m\u00eame de changer tous les mots de passe<\/strong> de vos diff\u00e9rents comptes (r\u00e9seaux sociaux, mail, PlayStore, Cloud, etc.).<\/p>\n","protected":false},"excerpt":{"rendered":"
