Important info for Windows XP users

Avast Free Antivirus still protects Windows XP owners with regular virus definition updates. But we no longer provide program updates, new features, bug fixes, or support for Windows XP. We strongly recommend upgrading to the latest version of Windows. (Remember, Microsoft ended its security updates for Windows XP back in 2014.)

Важная информация для пользователей ОС Windows XP

Программа Avast Free Antivirus по-прежнему защищает пользователей ОС Windows XP, регулярно обновляя вирусные сигнатуры. Однако обновления для самой программы, новые функции, исправления ошибок и техническая поддержка для Windows XP больше предоставляться не будут. Настоятельно рекомендуем перейти на последнюю версию Windows (помните: компания Microsoft прекратила выпускать обновления безопасности для ОС Windows XP еще в 2014 году).

Гладкая работа даже с Windows XP

Лаборатория AV Comparatives назвала Avast «антивирусом с самой низкой нагрузкой на системные ресурсы и производительность компьютера». Он практически не оказывает влияния на производительность Windows XP. Кроме того, дополнительные средства (например, Cleanup и «Очистка браузера») обеспечат еще более высокую скорость работы.

Официальный антивирус для Windows XP

Антивирус Avast был с успехом протестирован на ПК с ОС Windows XP независимой лабораторией AV Comparatives. Avast является официальным поставщиком антивирусных решений для Windows XP. Это еще одна причина, по которой более 435 млн пользователей доверяют свою защиту Avast.

Антивирус Avast совместим с Windows 10, 8.1, 8, 7, Vista, XP SP3

Avast может защитить ваши устройства с ОС Android и компьютеры Mac

О нас говорят

Мы будем рады узнать и ваше мнение. Ведь мы здесь ради вас.

The Windows XP operating system (OS) was the most popular OS released by Microsoft. The Windows XP operating system, codenamed «Whistler,» was widely used as it offered security, stability, and efficiency. Though Microsoft stopped extended support for this personal computer operating system on April 8, 2014, it is still being used in many organizations, ATM machines, small businesses and personal computers. Many organizations such as the National Health Service UK and many police forces still use Windows XP. As of April 2017, it was estimated that around 140 million PCs still ran on Windows XP.

Stoppage of Security Updates Makes Antivirus Protection Absolutely Necessary

Microsoft stopped issuing security updates for Windows XP in April 2014. From then on, Windows XP users have relied on antivirus solutions to protect their computers. Considering its popularity, there were hundreds of paid antivirus and free antivirus solutions released for Windows XP. However, with the lack of proper operating system updates and ineffective antivirus solutions, many computer networks running Windows XP suffered major attacks from various malware, including the WannaCry ransomware in May 2017. This ransomware encrypted data and demanded ransom payments in Bitcoins for decryption of data.

Why Windows XP Was Still Being Used

The justification provided for organizations to still use Windows XP was that legacy applications and devices did not support later versions of the Windows operating systems. Upgradation to supported hardware and software applications was expensive and beyond the budget. Still, organizations that had implemented effective cyber security systems were able to escape the clutches of the WannaCry ransomware.

Effective Free Antivirus Windows XP

What is the difference between a regular antivirus solution and an effective antivirus for Windows XP? An antivirus solution must have certain typical features, and an effective antivirus will have certain features that are not available in traditional free antivirus solutions, which will protect the computer from zero-day malware.

Features of Typical Free Antivirus Solutions

• An antivirus engine to identify suspicious files
• Virus database with up-to-date definitions
• Ability to immediately remove malware on detection
• Provide defense against all kinds of malware
• Provide real-time protection against malware
• Auto-scan of all downloaded files
• Auto-scan of all files delivered through the network
• Enable secure connection to the internet
• Must not affect system performance
• Comprehensive dashboard that provides detailed information

Comodo $7.99/year Antivirus Windows XP

The Comodo Antivirus Windows XP features a proactive antivirus engine that automatically detects and eliminates malware such as viruses, worms, and Trojans. It utilizes cloud-based scanning for rapid and efficient response to malware threats. The AV offers powerful on-demand, on-access, and scheduled scan capabilities.

Traditional AV solutions provide protection only against known malware. They block only known malware and allow all other files through. Only Comodo Antivirus features a default-deny platform that provides protection against all new viruses — it allows only known safe applications and files to make changes in the system. All unknown files are automatically run in a Comodo container, where malware believes that it is making changes to the system, but due to sophisticated virtualization of COM interfaces, Disk, Registry, and Memory, it is able to make changes only to the virtual system.

Based on the behavior of the file/application, a verdict is obtained and the file/application is allowed if it is good, or blocked if it is malicious. Comodo Antivirus Windows XP provides total security for Windows XP computers.
