Avast, like other antimalware vendors, has committed to supporting Windows XP for two years or more. It surveyed close to 165,000 of its users running XP and found that 27 percent of Avast’s Windows XP users don’t plan on doing anything.

Avast notes: “This number is relatively high considering the security risks involved with the OS and makes one wonder how many XP users are not concerned about their protection and aren’t planning on upgrading their OS, buying a new PC or seeking AV that will support them.”

What is interesting is that of its 200 million users, a survey of the 164,496 users who responded indicated that 21 percent of its Windows XP users were unaware that Microsoft was ending support for Windows XP. Only 15 percent of those Windows XP users were planning to upgrade their operating system and only 5 percent of users plan to buy an entirely new PC.
