I am posting here to see if I can identify the source or reason for these connections. I have already made a post in the Virus and Malware forum here: http://www.bleepingcomputer.com/forums/t/617403/strange-connections-from-svchostnetworkservice/
They have declared me clean from any malware or infection. Further details can be found in that post, but to summarize:
When I first log in to my PC, I get connections via Svchost(NetworkService) to a few IP addresses including an addr.btopenworld, 220.127.116.11, 18.104.22.168, 22.214.171.124, comodoca.crl, apps.digsigtrust and one to securenet. The most data received seems to be from the 126.96.36.199 or 188.8.131.52.. A connection to a google registered IP also occurs. 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 am on Window 7N, my connection is BT using a TP-Link adapter and a router.
Any help you can give in this matter is appreciated, thank you
