The following is the content of an email I received from Microsoft this morning. I feel like sharing with you and assist everyone to minimise the spread.
A virus known as Conficker.B has been detected in Malaysia.
A patch has been available to help protect against this virus since October 2008.
We are reaching out to you in order to provide information to help prevent the spread of this virus to your systems.
This virus affects Windows 2000, XP, Vista as well as Windows Server 2003 and 2008.
Worm:Win32/Conficker.B is a worm that infects other computers across a network by exploiting a vulnerability in the Windows Server service (SVCHOST.EXE). If the vulnerability is successfully exploited, it could allow remote code execution when file sharing is enabled. It may also spread via removable drives and weak administrator passwords. It disables several important system services and security products.
Microsoft strongly recommends that users apply the update referred to in Security Bulletin MS08-067 immediately.
Microsoft also recommends that users ensure that their network passwords are strong to prevent this worm from spreading via weak administrator passwords. More information is available here.
