I got several PCs on network at home, and recently noticed that I was getting really laggy net performance. I traced this to one PC that is absolutely HAMMERING the router causing it to consistently lag every 3-10 seconds. Funny enough it isn't using much bandwidth. Most net usage won't notice this, but online games certainly do.
Now while working on this, I found that a safe mode start gets rid of the problem, but shutting down every task I could think that could be shut down would not fix it. I've run numerous scans on the system and nothing has shown anything suspicious and it was recently rebuilt. So short of another rebuild, does anybody know a good program to track down what is using the networking in this kind of burst fashion (or even better what may be the issue)? I suspect it is malware as I can't see any legitimate program using the network this stupidly, but I don't want to go through a whole rebuild just to find out it is something I've dumbly installed.
