Internet help?

I recently got cable internet, through Comcast. It worked for an hour after the installer left, and has not worked since. I have spent hours on the phone with the Comcast techs, and have determined
that it is some program on my computer that is not allowing me to access the internet. I previously had McAfee and Symantec/Norton. The McAfee was corrupt, so I removed it, after speaking to McAfee people on the phone. Previously, I had suspected it was this corrupt version of McAfee that was causing the problem, but alas.
I can ping websites from the command prompt, but I can't access the internet through IE7 or Firefox 2.whatever. I can access the internet in safe mode. For some reason, hitting control+alt+del does not bring up the tast manager on the other account (I am admin in safe mode), despite the other account being an admin account too.
Can anyone help me please?

Open a command window and run ipconfig. What is your default gateway?
Open a command window and type telnet google.com 80. The command window will go blank. Type (you won't see the letters): GET / HTTP/1.0 and hit ENTER twice. If a bunch of text spills into the window, you can read google.com's main page. If nothing happens, port 80 may be blocked by your router or modem in some way.
Taking those steps will give us more info on what the problem might be.
Also, I was wondering if there was bad process or something. But I can't get the task manager to show up.
default gateway: 68.81.72.1
I did the telnet google.com 80 thing and got nothing. blackness, and a pause, and then the command prompt stuff.
The task manager thing is kind of a big deal, but I'm not sure it's related to your internet problem. I would recommend starting up in safe mode and attempting to uninstall (from the Control Panel > Add or Remove Programs) anything you see that doesn't look familiar.
Regarding the task manager. I'm assuming you can't get it to come up while in Normal mode. Have you tried right-clicking on the bar at the bottom of the screen and choosing "Task Manager" from the menu, instead of pressing ctrl+alt+del?
You can also do START>RUN "taskmgr.exe"
You really do have a promising career with the Geek Squad.
Open a command prompt. type:
ping www.google.com
See if you get a response (if not, you'll get a set of 'request timed outs') or maybe "destination net unreachable."
If it doesn't work, try pinging the IP address of your default gateway above. If you get a response, then your internet connection is fine but something is messing up your browser or your Web connections.
I have tried accessing the task manager in all of those ways. No worky. Also the command prompt. I am thinking it has a virus on it, somehow infected in the five minutes it worked. The inability to access the task manager/cmd when not in safe mode started yesterday morning.
Before that, I could ping stuff from the cmd.
After spending hours on the phone with Comcast techs, they determined the cable modem is fine, that I can access the internet (through the cmd and safe mode, plus the techs could ping my computer or see it somehow through the internet and my cable modem).
So I am going to install some virus protection to a CD, install that on the computer, and then try and connect it via the router and download all of the upgrades. I'll get back to you guys after all of that.
I've run into this exact problem before. Norton 2005/6 had some weird-ass issue with messing up the TCP stack when it got uninstalled. Go download SymNRT (official cleanup tool), run that, and see if you're not in better shape.
Edit:
CHESS!
CHESS!
Is it possible to install AVG to a jump drive, update that, and run it from that, while it is plugged into the computer? I am starting to think at least some of the blame goes to a virus. The Comcast peeps had me remove the virus protectors (mcafee, norton) because McAfee somehow became corrupt and Norton was interfering somehow. In the brief time the connection worked, I am guessing my luck caused a virus to lay eggs of evil in my computer and screw things up badly. A virus would probably keep the taskmgr and command prompt from showing up, right?
CHESS!
Is reinstalling really the only option? I have no idea where the windows install cds are.
okay, well, that being the case.....
AVG definitions can be downloaded for manual install here. I'd also recommend grabbing Ad-Aware and the latest definitions while you're at it.
Additionally, consider getting some additional tools to scan with, just to be damn sure the system's clean and nothing got missed. I'll name f-prot and spybot as secondary scanning/cleaning tools.
Once that's all come back and you're sure every thing's clean, you can try using this handy tool to repair internet explorer and a number of other things.
That should keep you busy for a while, and if that doesn't fix it, you're going to need to get the OS discs to try some other things, if not to repair/reinstall.
CHESS!
Still can't access the command prompt or task manager, but I am not detecting any more errors, virii, etc. What would cause that? Any ideas?
