Internet Exployer website restore eror

December 2, 2010 at 06:17:08
Specs: Windows XP

When I start exployer, I first get the home page flashes on the screen and then I get an error screen for code 0xc000005. This repeates for 2 to 3 times. After cycling though these error messages. I then get an exployer error pages stating that there is a website restore error.
The error code 0xc000005 code details are Iexployer 8.06001 with file tbzon1.dll

I have tried the following.
Spyware and Virus scans.
Restarting with a restore point .
Uninstalled Iexployer then reinstalled exployer.

All of these resulted in same problem . It seams to me that something is wrong with an addon or some software on top of iexployer. I can not access the tools menu in exployer to manage the add on because of the problem. What should I try next? I am ready to toss out this computer.
Thanks for Your Help

I'm assuming the error referred to Iexplore.exe and that you can't get online.

Search your file system for tbzon1.dll
If you find it in "C:\Program Files\ZoneAlarm" then it's probably safe (anywhere else it is likely to be a virus so ignore all that follows and report back).

I assume you use Zone Alarm firewall. Try "temporarily" disabling ZA then see if you can get to your home page. If you can then get to your homepage, something has probably gone wonky with Zone Alarm and it might have to be uninstalled and re-installed to fix the problem.

I have found tbzon1.dll in C:/program files/zonealarm This file is version with a description of Conduit Toolbar ver 1.0.. I also found a file named tbzone.dll version in the same directory and file description.

When I tried runing explorer after disabling zonealarm , I get the same problem. The home page flashes on and off then I get the same error message. When it flashes on and off , there are diffent tool bars on the web page.

What should I next.? Should I delete these two files ?

I know nothing about Conduit Toolbar, which is said to be spyware. Is this something you particularly want to use? If not then here is a website which explains how to uninstall it (which seems like a good idea to me, whether it's the culprit or not):

I normally don't advocate picking off files although if you do so temporarily and keep them in the bin for later restoration it might help your diagnosis. When you delete files you leave programs and registry entries in place which is likely to result in further issues. The correct option is to always do a proper uninstall of programs.

I removed all the files named tbzon1.dll as well as files that were variations of this file name. This seamed to solve the issue. Explorer is now stable.

Thanks For Your Help

Good news but generally it is best not to pick off files because it can often backfire.
Thanks for taking the trouble to pop back and let us know.

I had the same problem. Tbzon1.dll is in ZoneAlarm, but it is part of conduit toolbar owned by Conduit LTD, so I think ZoneAlarm has some sort of partnership with them, and I think I picked it up like a virus from Myspace or Facebook. So on to the solution.

Open Control Panel, then Internet Options, then Programs, then Manage add-ons. Then disable everything from Conduit. I did that, and IE 8 loaded right up. The coolest thing is that it was a no risk fix, because I did not have to delete anything or change the registry.

Zone Alarm Toolbar keeps re-enabling itself in the fix I posted above, so I went into the Zone Alarm control panel, and then "program control" and removed zone alarm toolbar. Zone Alarm itself seems to function ok, and IE8 works better than ever.

Yeah, most toolbars are a waste of space and likely to cause issues.

I also had this problem with Iexplore. The fault lead to tbzon1.dll. This file is part of a tool of Zonelarm. I deleted that "sub-programma of Zonealarm and the problem was solved. Tks to you all

Thanks for this. I'm having the same problem. To stop the loop on the ie restore tab I disable the ie restore in tools/options/advance. BTW #1 said he couldn't get into tools because explorer kept crashing. You can always get into tools via the control panel.

Back to the crash problem and my query

How did you disable the ZoneAlarm Toolbar?
When I look at Programs in ZA I can see ZoneAlarmToolbarHelper.exe

Is that what I should choose to remove?

Many thanks

Thanks but I can answer my own question!
I looked on ZA and they suggested removing ZA via Control panel/add remove progroams.
Then install latest version of ZA ( which installs the correct tbzone1.dll and hopefully resoves the problem.

Many thanks for help here. I'm going to award us all medals for getting to the bottom of this one. Like looking for a needle in a haystack but what fun!

I am a rather experienced computer operator and I have been reading the above posts concerning IE Crashing as a result of Zone Alarm.

I have been fighting the same excat website restore errors for a week now and tracked to Tbzon1.dll which is part of Zone Alarms conduit engine.

Your right in every instance. The only way to keep IE stable is to disable the
conduit engine under managing add-ons. The problem is the engine will restart
itsself at a check point. The only lasting solution is to uninstall Zone Alarm which I personally have used for many years.
