Максимальная защита. Будьте уверены в том, что ваш компьютер защищен наилучшим возможным образом от всех типов онлайн угроз: всегда, везде, в любой ситуации - и все это с минимальной нагрузкой на системные ресурсы в удобном, интуитивно понятном и красивом дизайне. Avast Premier, усиленный новейшей технологией Nitro, предлагает все самые продвинутые функции Avast на данный момент: CyberCapture для проверки всех неизвестных и подозрительных файлов, SecureDNS для предотвращения фишинговых атак, усовершенствованный брандмауэр для блокировки всех посягновений злоумышленников извне и многое другое. Уникальной для Avast Premier функцией является инструмент автоматического обновления сторонних программ, который проверяет наличие обновлений для установленных на компьютере сторонних программ и устанавливает их полностью автоматически в фоновом режиме: это не только сэкономит ваше время на установку обновлений вручную, но и существенно повысит уровень безопасности вашего компьютера от злоумышленников, способных использовать уязвимости в устаревших сторонних программах для проникновения в систему компьютера.
Вы будете удивлены, но ваши конфиденциальные данные могут подвергнуться риску компрометации не только посредством онлайн-угроз. Если вы намереваетесь продать свой компьютер или предоставить его в пользование, вы должны знать, что удаленные данные могут без труда быть восстановлены новым владельцем в несколько щелчков мыши — это означает, что конфиденциальная информация даже после удаления может оказаться в чужих руках. Устраняйте данные с помощью Уничтожителя данных, который позаботится о том, чтобы они были удалены полностью и без возможности восстановления.
The ultimate in protection. Have the confidence of knowing that your PC's security will protect it from every threat, every time, with plenty of speed and dependability, to make it your own. Avast Premier, supercharged with Nitro, offers all the features, benefits, and tools Avast has at our disposal: CyberCapture to examine risky, mysterious files, SecureDNS to avoid phishing attacks, an enhanced Firewall to block dangerous incoming traffic, and more. Unique to Avast Premier is the Automatic Software Updater, which scans your PC for out-of-date software and unobtrusively updates it for you, in the background: not only saving you the hassle of having to update your software manually, but also protecting you from the vulnerabilities out-of-date software creates in your PCs defenses.
Then again, not all threats are online. If you plan on selling your PC, you need to know that any data you've deleted can be recovered with a few clicks and a little know how meaning any sensitive documents you would rather stay deleted could be restored. Make sure what's been deleted stays that way with our Data Shredder, which makes all your erased files unreadable even if recovered.
