Svchost.exe (NetworkService) and its uploading to landauer.arvixededicated.com To check this go to your resource monitor under the network tab. If you go to the site it's something to do with Microsoft Internet Information Services 8.0 and then links to a Web development page. Now what concerns me is that my PC has been uploading to this site for the last 2 hours while I was afk, even now it's uploading on and off. I'm going to have to block the address if it persists, but would like to know if any one can explain whats happening here, or if they also have this mystery windows network service uploading randomly. And for the record I do no web development and I'm not hosting any files.
