Solved: Getting back online after viruses

[tgrover54]

Hi, I am really hoping you can help me, because I have tried everything. A friend asked me to help him with his computer, as I am pretty techie. He has a Toshiba L355D-S7901 with an Atheros AR5007EG wireless adaptor. He didn't renew the Trend Micro that came with his computer and has been running for six months with no protection! I couldn't believe it. All kinds of windows were popping up, it was a real mess. The computer is running Vista SP1. I have cleaned it up, and connection is there, but I still cannot get online. Here is what I did:

• I ran Malwarebytes and got rid of over 600 infected files and programs. I uninstalled Trend Micro and installed free Avira Anti-virus, which scanned and found 12 more viruses. I quarantined and removed all files. But one file cannot be deleted: Windows\System32\drivers\zaljvnzmw.sys. I even located it myself and it WILL NOT delete.
• No more windows popping up, but occasionally I get a message, like Host Process for Windows Services not found.
• I still cannot get internet.
• I went to Device manager, and noticed the 4to6 adaptors had no drivers. These shouldn't be necessary. Uninstalled them, and they did not reinstall on startup. But I'm not too worried about this.
• Went to Toshiba's website on another computer and downloaded the latest driver for the wireless adaptor. Uninstalled the adaptor (including software) and installed the new driver. Disabled Windows Firewall and Avira--still no getting online
• ran ipconfig, got ip addresses. pinged the router, got back replies
• Re-enabled Firewall and Avira--I sure don't want any more viruses!--but I am stuck.

I had one situation where I was told to re-name the Host in the System Root drivers/etc area. I even tried this, though I'm not sure what it is all about. No luck. So, I changed it back to "Hosts". Can you help me with this situation? My friend is about to throw away a $500 computer. Incidentally, I went into the LAN properties, and did not see a TC/ICP (sp) listed there. Help!

Does it get internet access with an ethernet connection?

Does it get internet access with an unsecured wireless network?

 

[tgrover54]

Thanks for answering, TerryNet. No, it does not get online with an ethernet or an unsecured network. It does say it has a connection, as I said. In Network and Sharing Center, it shows as connected to a network, but IE cannot show web pages. Incidentally, I have forgotten how to change the host name in the System32 driver/etc files, which did work in another situation for me. Can you help me try that? Or, any other solution would be most welcome.

If no luck, use a USB flash drive and,

Thanks, Phantom. Here is the log--I did this with the wireless connected to the network "successfully":

Run HijackThis again.

Select Do a system scan only.

Put a check mark on:

R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyServer = http=127.0.0.1:8074


Click Fix checked.


Try browsing again.

 

[tgrover54]

Wow! That worked. You are a genius. Can you please explain to me what this is all about so I will be able to do it again if/when I confront this issue? Was it the IP address for the host? What would I look for on another computer if I had the issue (I seem to have seen this happen on several--yes connection, no internet). Thanks so much, I can sleep again now.

 

[Phantom010]

Malware will often change Lan settings and configure proxy settings by "tunneling" traffic through a certain port (e.g. Local address: 127.0.0.1 Port: 8074).

Next time:

Open Internet Explorer. Click Tools > Internet Options > Connections > Lan settings > Proxy server > Advanced > delete proxy server settings > click OK > uncheck all boxes > click OK.

In Firefox, click Tools > Options... > General > Advanced > Network > Settings > delete proxy settings > select No proxy > click OK.

 

[TerryNet]

When you have internet access but browser(s) don't work the most common causes are a proxy, mis-configured or corrupted non-Windows firewall and corrupted stack/WINSOCK.

 

[tgrover54]

Thanks for the education, guys. I will definitely add this to my "fixing computers" folder.

You're welcome!
