I'm trying to fix a poor internet performance and have narrowed it down to apparent bottle necking when a certain PC (running Windows 10) connects to the network (wired or wireless). Everything is fine without it connected but when connected ping spikes and download speed become unusable on all devices on the network. Malware bytes etc. has failed to pick anything up but I'm suspecting something bot net based or some other high traffic malware is in there somewhere causing the jam but hiding itself. Can anyone offer any advice/steps to take? Research has pointed me towards combofix, is this a good idea?!


Thanks in advance


edit: File transfers on two other machines within the network seem unaffected by its presence so I'm ruling out network bottleneck and think it must be saturating the (already poor) internet connection.
