Keeps Disconnecting from the Internet

By dprivette ·
Have an HP computer running XP that recently was infected with the Blaster Virus. It was successfully removed but now the computer continuously disconntects itself from the internet (MSN w/Dial-up) stating that "due to a firewall you have been disconntected....etc." It will stay connected for 1-5 minutes before this msg comes up and disconnects. I have verified that the internal firewall in XP was not enabled, I have also had MSN support on the phone who had me recreate the MSN profile. I have run diagnostics on the modem which show it is working fine. I have replaced the phone cord. Not sure where to go next with this, I know this is not a symptom of the Blaster Virus but that is the only common denominator I can come up with since this started the first time the computer was used after removing the virus.

There are a couple of situations in which your computer would disconnect you from the Internet.

You may be getting disconnected because your Internet connection idle time had reached the limit. Your computer has a time-out setting. To check your "idle timeout" setting:

If using Windows Dial Up Networking:
Double click on "My Computer"
Double Click "Dial-up Networking"
Right Click over your Internet connection
Single click properties
Click the "Configure" button
Click the Connection Tab
You should now see a tick box with "Disconnect a call if idle for XX minutes"
Untick this box if it is ticked.

You may be getting disconnected because you have Outlook Express set to disconnect after you have checked your e-mail (pressing the send and receive button). You can check to see if this is set by doing the following:

Open Outlook Express,
Click tools at the top,
Click options from the drop down menu,
Click the connection tab
From here make sure there is NO tick in "hang up after sending and receiving".
Click OK to save the changes.
Done.

If you didn't see the connection tab, then click the dialup tab,
From here, make sure there is no tick in "Hang up when finished sending and receiving or downloading"
Click Ok to save the changes. Done.

that error message is weird. can you give it to us exact? is it possible for you to set up another dial-up account and see if it stays up longer than five minutes? what is running on this computer (Start/run/taskmgr <enter&gt. what is trying to get updated/connected out on the internet? windows update? realplayer? kazaa? mcafee? norton? quickbooks? if you make everything cut that out, does it stay up then? have any other firewalls been installed and uninstalled recently? check their websites for this error...i wonder if anything would be in the event log...and what about giving ad-aware a whirl, get the spyware off...

" I know this is not a symptom of the Blaster Virus ", you are mistaken...
The worm causes the remote machine to acquire a copy of the worm, which is saved as msblast.exe in the Windows System and System32 folders.
Symptoms
Finding your computer cannot connect to the internet/network.
Download and install the patch.
1. Disable System Restore (Windows XP)
If a worm infects a computer, System Restore may back up the worm.Windows prevents outside programsfrom modifying System Restore. Tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.
Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat.
2. End the Worm process
a. Press Ctrl+Alt+Delete once.
b. Click Task Manager.
c. Click the Processes tab.
d. Double-click the Image Name column header to alphabetically sort the processes.
e. Scroll through the list and look for msblast.exe.
f. If you find the file, click it, and then click End Process.
g. Exit the Task Manager.
3. Reverse the changes made to the registry
Modify the specified keys only!
a. Click Start, and then click Run. (The Run dialog box appears.)
b. Type regedit
Then click OK. (The Registry Editor opens.)
c. Navigate to the key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
d. In the right pane, delete the value:
"windows auto update"="msblast.exe"
e. Exit the Registry Editor.
Reboot. Try the internet connection. If OK, turn on System Restore.

Major antivirus manufacturers have taken steps to combat this worm.McAfee VirusScan provides Stinger, a stand-alone utility that detects and removes viruses from infected systems. Download Stinger, and follow the instructions provided by McAfee to remove the Blaster worm.

I understood the virus was not written well and there was some bugs into it, that affected other parts of the os.
There several variants of the blaster make sure to run this tools to remove all variants.
http://securityresponse.symantec.com/avcenter/venc/data/w32.blaster.worm.removal.tool.html

after that reinstall xp servicepack 1a
http://www.microsoft.com/windowsxp/home/downloads/default.asp
and then the patches.
Else I am afraid you have to reinstall the pc.
