I cannot connect to the internet. Network Diagnostics says "Windows has detected a problem with the Winsock provider catalog on this computer. This catalog allows programs to communicate with this computer across the network...."

The computer was running ok, but I ran a full scan with Avast Free Antivirus. It found and removed the following problem - Win32:Alureon-FZ, file name C:\Windows\system32\drivers\ipsec.sys.

The Network Diagnostics asks "Would you like Windows to reset the catalog to the default configuration? I have clicked yes, restarted, and the problem is not fixed.

I have Windows XP home edition, SP3. I don't know what other information you would need but please ask and I'll do my best to provide it.

Thanks in advance, Mike

Did you delete or quarantine the Ipsec file.?

We may need to put it back.

Try this--open control, internet options, connections tab, lan settings, uncheck the box next to "use proxy...."
OR
Go to Start ... Run and type in cmd
A dos Window will appear.
Type in the dos window: netsh winsock reset
Click on the enter key.

Thanks.. I checked and use proxy was not checked. I have tried to do the netsh winsock reset a couple times and that does not work either.

I'm stumped. It seems like the file that Avast removed was maybe a critical component because everything was working fine up to that point.

By the way I had Avast delete that file. I've checked in the scan log and there is no option to restore it. Can that be done manually?

Try running SFC

Please run System File Checker sfc /scannow... For more information on this tool see How To Use Sfc.exe To Repair System Files

NOTE for Vista users..The command needs to be run from an elevated Command Prompt.
Click Start, type cmd into the Start/Search box,
right-click cmd.exe in the list above and select 'Run as Administrator'


You will need your operating system CD handy.

Open Windows Task Manager....by pressing CTRL+SHIFT+ESC

Then click File.. then New Task(Run)

In the box that opens type sfc /scannow ......There is a space between c and /

Click OK
Let it run and insert the XP CD when asked.

The SFC completed. It didn't ask me to put in the CD, and it did not fix the problem.

Hi :thumbsup:.

A couple of things we can try. It looks like resetting the TCP/IP setting may clear up things.

See http://webcache.googleusercontent.com/sear...=clnk&gl=us.

It may seem complicated, but it's really not. I had to do this a couple of years ago (which means that all you have to do is follow the instructions :flowers:).

The error message that you receive has two listed alternatives for solving...I'm not sure why sfc /scannow did not install the correct file...unless you used a CD that did not reflect SP3...but this is the alternative way of replacing ipsec.sys.

That didn't work.

When I click 'Diagnose Connection Problems' and click View Diagnostic Log, the errors I get are

Provider entry MSAFD Tcpip [TCP/IP] could not perform simple loopback communication. Error 10050.
Provider entry MSAFD Tcpip [UDPIP] could not perform simple loopback communication. Error 10050.
Provider entry RSVP UDP Service Provider could not perform simple loopback communication. Error 10091.
Provider entry RSVP TCP Service Provider could not perform simple loopback communication. Error 10091.
A connectivity problem exists with an installed LSP.

Not sure if this is helpful but just wanted to throw it out there.

It's been over a week since I've gotten a response... I guess you've given up. Thanks anyways.

I feel this is a driver issue or even your network card is bad or loose.

To rule out malware you need to make a disk.
