So a week ago I made this post: http://www.bleepingcomputer.com/forums/t/616398/why-is-svchostexenetworkservice-making-strange-connections-when-i-boot-up/#entry4015948

 

To recap:

When I first log in to my PC, I got connections via Svchost(NetworkService) to a few IP addresses including an addr.btopenworld, 104.16.93.188, 93.184.220.20, comodoca.crl and apps.digsigtrust. The most data received seems to be from the 93.184.220.20. I first noticed all this months ago but couldn't find a reason, and various tools and scanner turned up nothing, my pc continued to run fine. The connections also occurred when connecting to Steam and when Premiere Pro or other adobe products were transmitting usage data. It also occasionally does it while I use chrome. I used Process Explorer and the service within Network Service that was making the connections was CryptSvc.

 

My work PC makes a connection like the ones described above when it boots up, though its to akamai. My brothers computer also had many of the same connections that mine did. So now I want to actually know what is causing these checks? I have checked startup programs on my PC, all I have is Avast, intel usbmon 3.0 and something by creative technologies that I believe is sound related. Does anyone else experience similar connections?

 

I am on Window 7N, my connection is BT using a TP-Link adapter and a router.

 

Any help is appreciated, thank you   :)

 

Just some more info. MalwareBytes, Avast and HitmanPro turned up nothing. AdwCleaner found a file, but it seems to be an auto generated file when you save in Deus Ex Human Revolution, so it was a false positive. I ran TDSSKiller. It found 1 suspicious file. RzWizardService.exe located inside Razer file. I have a Razer keyboard, and the reason it flagged it was it was not digitally signed. Removed the file anyway but it seems to have been a false positive :/

I have only posted this here as someone in the Networks forum suggested it, and I would like to know what this is.

Please follow this Preparation Guide and post in a new topic.
Let me know if all went well.

You're welcome.
Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.
From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.
Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRL Team member is already assisting you and not open the thread to respond.
The current wait time is 1 - 5 days and ALL logs are answered.
If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
To avoid confusion, I am closing this topic.
