I would reinstall both your browser(s) and your download client(s) (uTorrent, Az, etc).
I recommend this because it sounds like uTorrent is taking up all your bandwith, so if you reinstall it, it might reset it to its original settings.
If that doesn't work, try limiting the download speed in uTorrent. This is done by right clicking the uTorrent tray icon, highlighting "download speed" and selecting a lower setting. Adjust this and see if your browser and other programs work on a lower setting.
Also, to humor us run speedtest and tell us the results.
Man you made me LOL specially with above thing

my download speed is a constant 28+ Mbps and my upload is 1.05 Mbps..not too bad,huh?
Im using Utorrent for abou 5 years and of course it will slow your internet speed,any torrent client would.but in 5 years I've never experienced that during Utorrent usage my internet browser would not work at all.
are you sure its utorrent?? ie9 and FF do it to me even when i dont run utorrent. chrome works fine
When not running Utorrent,never have any browser issue with FF4.IE9 I use very rarely.I've tried to install chrome and its happening with it too,so its narrowing down to Utorrent..but surely there still might be something else..If you google this issue with Utorrent,actually lot of stuff comes up,but its all dated like 2007 - 2010,nothing very recent.there is stuff about some kind of patch but its all for Win XP.
Interesting little dilemna you have here.
Do you have another computer on the network?
If so, can it access the internet when you have torrents running on your rig?
That will narrow things down a bit.
this was probably the most reasonable reply yet,so thanks buddy,but of course I appreciate all of the other guys replies too...
So after reading your post Kreij,I've done a little experiment.I run Utorrent on my main rig,of course browsers stopped working,then I turned on my lappie and..on wireless it worked without any issues.then I hard wired it with my router and this also worked fine.then I run Utorrent on my lappie too and wow..browser still worked I was like wait a moment uumm...(Utorrent on my laptop was allready updated to the same latest version as on my gaming rig,so its not the version that sucks)..then on my laptop,I run in Utorrent the setup guide,which supposed to determine the best possible speed settings,which when you finish the test,auto set to maximum possible speed...then the browser stopped working on my lappie too!!!..WAIT WAIT guys,before you say "you see I told you that its Utorrnet taking all your bandwich..cos then I decreased these speed settings in Utorrent(just like I've tried previously on my gaming rig too) and this unfortunately doesnt not put things back to normal..so what is the conclusion so far?I think there is something else that Utorrents setup guide fucks up while trying to do the best for you..
Is the rig your using wireless, or hard wired? Had the same issue as you are now having with my wireless access rigs. In the end I dumped utorrent and started using Tixati. utorrent just likes to go haywire to much, at least in my experience.
well I just love Utorrent too much,dont want to dump it so quick..after all,as I said over 5 years I never had similar issues..to answer your question,my main rig is obviously hard wired
