Microsoft: ' Need to update Adobe Flash Player immediately '

Microsoft warned against the version of Flash Player included with Windows XP that contained many bugs and recommended Windows XP users to update to the latest Flash Player version.

The default version included in Windows XP is Flash Player 6. This version has been discontinued by Adobe and security updates since 2006. The Adobe Flash Player for Windows has been developed to version 10.0.42.34.

Users of Windows XP who regularly update the latest Flash Player will not have to worry about these errors.

In addition to Windows XP, Windows versions such as 2000/2003 / Vista / Server 2008 or Windows 7 are not affected by bug threats in Flash Player 6 due to the version of Windows operating systems that integrate Flash Player newer. However, the danger is that Windows XP is now a widely used version of Windows on desktops, laptops and especially netbooks.

Adobe is a software company that has a big impact on computer users, which is not inferior to Microsoft because its software applications are installed on most computers around the world, regardless of the Windows or Linux platform. Therefore, these applications are also the top target of hackers because the level of exploitation is very large and most users still neglect to update the patch released from the manufacturer.
