What can I use to measure the bandwidth a specific Windows application uses?
I recently got a Dell Inspiron to replace an ageing desktop. I use my new Dell to connect to the internet. When I checked my Internet usage last evening, I noticed some 280 MB has been uploaded. This has never happened before. All i do is check my mail and chat with a few friends. I've never uploaded anything this large. What program could have done this? (And its done it this morning again. Some 80 MB)
Could you pls suggest an app that can monitor in real time what apps from my laptop are accessing the net and vice versa. I use Google Chrome to browse the net.
I have McAfee installed on this machine and fully updated. I don't run any file sharing apps either.
Thanks,
Netbalancer did the trick! I blocked something named svchost.exe, and now all seems to be quiet. Only Chrome seems to be downloading and uploading stuff, and another 'something' called 'service traffic'. – Norman – 2012-04-26T13:21:44.623
I know you say you have Mcafee, but I would strongly recommend doing a full and thorough anti-virus scan when booted from a cd as I don't think that is the end of the problem. The legitimate svchost is used by windows to run services and you normally see several copies running and each copy runs several services. Some of these may need access to the internet and so blocking them can cause problems. And because this name appears rather than the underlying service, it is hard to determine what is actually triggering the upload. And so the name svchost is very commonly used with viruses. – sgmoore – 2012-04-26T14:25:37.697
Assuming it is not a virus, then if you highlight the offending scvhost in Netbalancer, it should show you the process information including the path and which services are associated with that copy of scvhost and the ip addresses that it is connecting to. This might identify and thus allow you to stop/uninstall the offending service. – sgmoore – 2012-04-26T14:35:22.973
3Just for the record, blocking
svchost.exe
is a BAD IDEA. It's the "Windows service host" which is to say that every window service (Control Panel->Administrative Tools->Services
) is represented by this one executable. Thats not to say you don't have a malicious service installed but blocking this will cause a LOT of problems (eg windows clock not synching properly, domain issues, any servers won't run, some apps rely on services, etc, etc). Find the problem service and uninstall it but don't blocksvchost.exe
