uTorrent Update -> No more P2P/ General Connectivity Problems

[yeptryagain]

I let uTorrent update a few weeks ago after ignoring the message for a while and all downloads went red. Now no download works, other torrent clients don't work, couldn't even get Filezilla. Also, I have had some problems connecting to my school's wireless network. None of them seem to be able to connect to the net at all. Also, I am pretty sure the problem is with my computer as uTorrent works on my old, dying laptop. I have posted my setup etc below. please help

Symptoms

-All torrents Red (no traffic)

-Port Test: Error! Port 48978 does not appear to be open

-All Trackers Say: "No Connection could be made because the target machine actively refused it"

-DHT: Waiting to log in (not sure what this means exactly, but disabling firewalls etc. doesn't help, neither does killing them with task manager.)

Computer (Gateway M-6850FX Laptop)

-Intel Core 2 Duo T5550 (1.83GHZ, 32Bit)

-3.00GB Ram

Software

-Windows Vista Home Premium

-Symantec Antivirus 10.2

-COMODO Firewall v3.0.25.378

Network

Router: Linksys WRT160N

ISP: Comcast

Speed: 4359Kb/s Down, 3726Kb/s Up

Attempted Fixes (With firewall, windows firewall, and anti virus disabled)

-Different Torrents

-Default Settings

-Uninstall/Reinstall

-Downgrade(am back on 1.8.1)

-Port Forwarding (undone so I can connect at school)

-Other Clients (BitTorrent, Vuze, Bittornado, Bitconjurer)

Nothing I have tried so far has made difference, please help.

Thank You

Perhaps Comodo is misconfigured. Try uninstalling Comodo to clear all the settings to make sure it's not blocking anything.

You may ultimately have to ditch symantec as well, though I'd do it anyway, since it's a lousy antivirus.

Indeed, I've seen Comodo cause very odd problems when not configured properly. Remove all µTorrent related rules in Comodo and recreate them: http://forum.utorrent.com/viewtopic.php?pid=292343#p292343

Can you clarify what you're referring to when you mention your school connection...? In general, you can't torrent on most school networks.

Problem Solved, Thank You!!

-I uninstalled Comodo, no change.

-Then tried uninstalling Symantec. No internet! (This is the same problem I was having at school, local connectivity only, but no ping from router?)

-Used Symantec removal tool. All good. Took me several hours to find that I need the stupid removal tool, which was frustrating, but that's it, I'm done with Symantec (It was required to access CMU's network).

Thank you for your help!! I have one final quistion (not sure if I've already read it somewhere here, I've been all over the site, but I am exhausted). Are there recommended, free, firewall and antivirus prog's that don't cause problems with uTorrent. I used to have zone alarm but it caused problems with vista and crashed all the time and I'm not really a fan of Comodo.

Thanks Again!

ps. URL for Symantec Removal Tool in case anyone else has this problem:

You can reinstall Comodo now.

Why don't you like Comodo though?

AVG Free is fine, long as you don't install the email scanner.

[Ultima]

AVG comes up with odd false-positives >_> (well, there have been at least 2 recent false positives -- one on a core Windows component, and another on, I believe, Flash)

[yeptryagain]

Comodo gives me non-firewall related warnings all the time, for example when using Visual Basic (legal from dreamspark) I get warnings all the time on different things.

Turn off the Defense+ feature. There's probably other features it has that can generate a bit too many popups.

[Ultima]

Defense+ is basically an application firewall that controls whether an application can or cannot perform specific actions (read/edit the Registry, add a startup entry, etc). Unless you feel like training it, you should disable it (as you've already noticed, it's rather noisy).
