I'm having an extremely annoying problem with a process called "svchost.exe" interfering with my internet connection when I'm playing online games. It has a large effect on my ping, making them nearly unplayable. I use COMODO firewall, and to check if svchost really was the culprit, I terminated all of its active connections and tabbed back into the game. For a few minutes, everything was fine.. Then the lag returned. I tabbed out, and found that svchost was connecting to something again. I repeated this several times to make certain, and it is indeed svchost causing this problem. I then tried blocking it from accessing the internet. I went to Firewall/Network Security Policy, found the file in the list, and set it to "Block All Incoming and Outgoing Requests", but that had absolutely no effect. As I type this, COMODO shows svchost.exe is responsible for 98.9% of my internet traffic despite it supposedly being blocked. I did a Google search for "svchost.exe", and found several different explanations as to what it is and does. I've read posts from other forums saying they've blocked it with their firewall with no ill effects, others say it prevents websites from loading if you do so.. However, I found no one complaining about being UNABLE to block it at all. Would anyone happen to know what I might be doing wrong, and how to go about successfully blocking this program?
