Unable to sign into anything

Hi, I'm new to the forum realm so I apologize if I'm not posting this in the proper location.

I have been having trouble when logging into anything. Gmail, youtube, twitter, stumbleupon, etc. Whenever I try to to log in, the page grinds and eventually I get "connection has timed out." I've tried using different browsers and its the same thing. I've enabled cookies, cleared the cache, reset/reinstalled firefox, deleted saved passwords, disabled my firewall, signed on as another user and nothing has worked. I've searched the web and can't find any solutions to this problem.

Does anyone have any ideas?

(I am currently running leopard.)

Just a thought. Have you tried resetting your router.

I tether my phone to my laptop. It may also be helpful to know that (to my knowledge) I haven't downloaded or installed any new applications to my mac since I've been having this problem.

are you using wifi, router, or directly connecting?

I am connected directly.

Maybe this has nothing to do with it, but i tried installing a couple free AV programs and I can never get past the definition update. Maybe a port is being blocked? I checked my proxy settings and everything seems in order.

FYI: If you regularily communicate with a Win machine, then an AV prog is moslty unnecessary. Altho I find it rather confusing, ClamAV would be probably the only AV program you should need as it scans for Malaware and virii. It doesn't slow your machine and is made for the mac rather then being new to it.

Try starting your mac in Safe Mode.. If you can connect and Login with no problems then it probably has to do with a 3rd party program..

I'm not sure if it will help with your problem, I've found also that sometimes fixing Permissions and running Verify Disk can sometimes help. Note: If you don't have Onyx (the correct version for you OS) then it's a good program to have.

This sounds like the problem to me.. I sometimes tether my phone to my laptop and if the phone doesnt have good service or the page is way too complex you will get that message.. When tethered your laptop will open the regular page instead of the mobile site, some of which we huge for a 3G connection to handle. Also if your moving you phone will go in and out of service areas and this can also be an issue. Does this happen when connected to the Internet via wifi or direct connect with cat5?

Installing "a couple of anti-virus programs" (when there are no viruses for the Mac) sounds more like the problem to me.
