Endpoint Protection

I have Symantec Anti-virus version 10.2.0.276 

I recently upgraded Firefox and now it won't work. I can't get on the internet at all with Firefox. My Windows Firewall if off for sure and nothing else is running. I've got to get this fixed. I've tried so many different things to try and get it to work. I've turned off auto-protect but that doesn't seem to do anything. I can't seem to find where to turn off the firewall all together to at least test the problem.

Thanks

Oh I run Windows Vista

Hi Tnissen,

First thing, whether the client is managed or unmanaged.

For Managed Client: -

• The firewall rules can be confired from the manager.
• If you want to stop symantec firewall you can stop the symantec management client service. Use the command smc -stop.

For Unmanaged Client: -

• Go to change settings and select network threat protection configure settings.
• One can use the same command to stop the service (smc -stop to stop the service and smc -start to start service)

Regards,

 Have you tried other browsers such as internet explorer, google chrome, or opera? Also see if you can ping other ipadresses on the internet. If you can do this then it is a problem with just firefox and NOT your internet connection. To do this follow the steps below:

1. Click start then run
2. Type cmd then hit enter
3. When the window with the black screen loads type ping www.google.com and hit enter
4. If you have an internet connection you will see 4 lines that say something like

"Reply from 74.125.105: bytes=32 time=300ms TTL=52"

After doing what Grant has suggested and you have verified that Firefox is the issue, you might want to look at the Firefox forums for an answer. There seems to be many users experiencing the same type of problem after upgrading.

I have looked at the Firefox forums...

I was able to run Chrome for about a week after I lost Firefox but now Chrome is gone as well. Only Internet Explorer works for me.

I have read about many similar problems on the Firefox forums so I was decently content that it was their problem until Chrome went out. And I can't seem to turn my firewall off to even test it out.

The firewall is through my college so I don't have all controls over it (annoying) and I won't be able to change any admin settings. I'm not sure what's up, but it's very frustrating because IE isn't anywhere as good as Firefox or Chrome.


Thanks

 hmm tnissen this is strange. If you are able to reach the internet with IE then it is very unlikely that it is a firewall issue. Do you know if your school is maybe putting in a proxy or something? Also just to be clear when you say "chrome is gone as well" or "cant get on the internet with firefox" you are saying that you get the page not found error for both of them right? 

Grant-

I wouldn't think they have put anything new in place, nor have they issued any statements which they usually do when they upgrade the system or such.

I get the "Webpage is not available" for both of them when I open them up. It's really very odd. Is it impossible to turn off my version of Symantec Anti-virus to test?  I can't seem to find the place where I can just turn it off. When I right-click on the yellow shield there's an option that says "Enable auto-protect" and when click that it then shows the red circle around the shield for a few moments but then that goes away.

Thanks

Update...

I just downloaded Maxthon2 browser and it couldn't connect to the internet either. Definitely some kind of firewall setting.

Can you check for Proxy settings in IE?

Open IE, go to Tools>Internet Options>Connections>Lan Settings. Is Proxy server selected? If so, then enter the address shown there into the Firefox network settings.

Open Firefox >Tools>Options>Advanced>Network>Settings, select manual Proxy configuration and enter the information found in your IE settings.

There is no proxy on IE.

Thanks

Please  try  disabling  the tamper  protection. If it allows Firefox to work, then you may exclude firfox from tamper  protection.

Regards,

I tried that and it didn't work.  I turned off tamper protection and still nothing.


Also, I did what Grant_Hall said earlier and did the command thing and it came up and said that that is not a recognizable internal or external command.


I'm getting desperate.

If possible , try to enable the Windows Firewall and add Firefox in exception program list.  See what happens.
In case of the same negative result, disable again the WIndows Firewall and try again to open a webpage with Firefox.

Don't know why the ping command would come up with not a recognized command error. You must have typed it wrong, since I has been installed on every Microsoft operating system since windows 95. Just to be clear the command is:

ping www.google.com

If you are having firewall issues this should fail. The only thing that makes me think it can't be a firewall issue is because of the way the browsers "went out". They should have all just stopped working, not firefox went down first then chrome ect ect. Have you tried a full scan in safe mode yet? If not try a full scan in safe mode with system restore off. Sometimes if you have a virus it can keep you from reaching the internet (or at least certain sites). Usually the virus will keep you from reaching the anti-virus sites like www.symantec.com, to keep you from being able to seek help or update your virus definitions. It doesn't really make sense that the virus would keep you from reaching the internet period, but stranger things have happened.

Hope you get your internet back soon : (

Grant-

Ahh shoot I just remembered something from college too. My roomate got his internet shut off (no warning just page not found error) for illegal downloading. Most schools have that policy in place, and reserve the right to shut off your internet at any time. So maybe you should check that out too.

Cheers again,
Grant

Any news about this issue ?

I've had a similar problem regarding installing and using Google's Chrome browser.  It seems to be blocked by Symantec, and is logged under the Client Management Control Log.  It simply blocks Chrome every time it attempts to access the internet.  I created a rule in the firewall to allow Chrome passage, but it remains blocked.  Any advice?

Symantec Endpoint Protection version 11.0.1000.1375

Windows XP SP3

On a home network, so don't have to mess with college interference.
