Avast discontinues support for Windows XP & Vista | AvastAvast 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.
