This is my First time in ESET and i proud.

Please let me know if it is  Fake Update Or not

No , I am in doubt about these servers Because usually i got all updates From USA IPs. not from Saudi Arabia that's why.


sometimes  svchost.exe  infected and  redirect the connections  to malware DNS.

How can i make sure if  its real update ?


Thank you.

Looks suspect to me. According to Robtex, here are the IP address associated with that domain name:

CTLDL.WINDOWSUPDATE.COM uses the 18 IP addresses,,,,,,,,,,,,,,,, and which also one other use.

Do you reside in Saudi Arabia? Appears to me that Internet traffic is being routed through servers there. I also saw a reference to Iran in the lookup.


Saudi Arabia directs all international Internet traffic through a proxy farm located in King Abdulaziz City for Science & Technology. A content filter is implemented there, based on software by Secure Computing.[5] Since October 2006, the Communications and Information Technology Commission (CITC) has been handling the DNS structure and filtering in Saudi Arabia in the place of KACST. Additionally, a number of sites are blocked according to two lists maintained by the Internet Services Unit (ISU):[6] one containing "immoral" (mostly pornographic or supportive of LGBT-rights) sites and sites promoting Shia Ideology, the others based on directions from a security committee run by the Ministry of Interior (including sites critical of the Saudi government). An interesting feature of this system is that citizens are encouraged to actively report "immoral" sites (mostly adult and pornographic) for blocking, using a provided web form, available on the government's website.
