Beginning this January, Avast products will no longer update Windows XP and Vista OS with new security features.
Avast cybersecurity products will officially stop updating our antivirus product for Windows XP and Windows Vista operating systems as of January 1, 2019. The demand to protect those systems has substantially waned in recent years at the same time that the need to protect Windows 7 systems and later has grown. We recommend that all Avast users update their Windows operating systems to the latest version of Windows 10 — not only to continue enjoying the newest Avast security upgrades, but also to eliminate the likelihood that the vulnerable older system you are currently using will get exploited.
Older system users who have not updated will continue to be protected by the corresponding older versions of our security products, even receiving virus definition updates, but they will not benefit from the newest programs and features. If you have any questions about this End of Support notice, just reach out to Avast Support for answers.
