Yesterday, we accidentally picked up a virus that kept routing our google searches to Shopica and februaryfinder.com. I have symantect endpoint protection and ran that...Nothing. I then ran an online search recommended by this site which found and deleted one virus. I then ran superantispyware in safemode and that found 2 threats and deleted them. When I restarted my computer I get the "Error loading NFR.DLL" message and when I try to connect to the internet, there is no connection and diagnostics says it is a firewall problem. I have been running MBAM a few times and it finds absolutely nothing wrong at this point.
Anyhelp you could provide would be great

Hello and welcome..
Its not unusual to receive such an error after using specialized fix tools.

A "Cannot find...", "Could not run...", "Error loading... or "specific module could not be found" message is usually related to malware that was set to run at startup but has been deleted. Windows is trying to load this file but cannot locate it since the file was mostly likely removed during an anti-virus or anti-malware scan. However, an associated orphaned registry entry remains and is telling Windows to load the file when you boot up. Since the file no longer exists, Windows will display an error message. You need to remove this registry entry so Windows stops searching for the file when it loads.

To resolve this, download Autoruns, search for the related entry and then delete it.

Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if you're not sure how to do this.)
Open the folder and double-click on autoruns.exe to launch it.
Please be patient as it scans and populates the entries.
When done scanning, it will say Ready at the bottom.
Scroll through the list and look for a startup entry related to the file(s) in the error message.
Right-click on the entry and choose delete.
Reboot your computer and see if the startup error returns.

Thanks very much for helping me. That worked and when I restarted, I did not get the error. I still however can not connect to the internet. When I start IE, I get the "internet explorer cannot display the page" and when I diagnose connection problems, I get the following error message:

"Windows cannott connect to the internet using HTTP, HTTPS, or FTP. This is probably caused by firewall settings on this computer. Check the firewall settings for the HTTP port (80), HTTPS prt (443) and FTP prt (21).
You might need to contact your internet service provider (ISP) or the manufacturer of your firewall software"

Any idea what is going on? I can connect using my other computer, so I know if is related to the virus removal and not my connection.
Thanks

Ok I am moving this out of "Infected" to "AntiVirus, Firewall and Privacy Products and Protection Methods "
So we get more skilled eyes on this.
Confirm it 's a Firewall issue by diabling the firewall and connect to BC only again and see what happpens. Of course reenable the wall after.
What is the Firewall you are using and is this an XP machine?

I turned off my windows firewall and but I could not get any connectivity. I dont think I have any other firewall. My antivirus that I usually use is symantec endpoint protection. when all of this happened I installed superantispyware and Malwarebytes Anti-Malware. Maybe it has to do with one of these?
I am using a XP machine
Thanks

Hopefully this will help. Were you able to scan with Superantispyware and Malwarebytes and get a log? Did they find malware?

See if this fixes your Net issues .

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.

Reboot your system to complete the process.

Check to see that your internet isn't trying to connect through a proxy on port 7070. This particular redirect virus sets up a proxy as part of the infection. If you remove parts of the infection, this setting in all likelihood won't get changed and your computer will be trying to connect through a proxy that doesn't exist, leading to no internet.

If you have firefox and IE, make sure you change it in both.

Firefox: Click Tools ==> Options ==> Network tab ==> Settings ==> Look to see if a proxy has been set up, odds are it'll be on port 7070 ==> Click "No Proxy"

IE: Click Tools ==> Internet Options ==> Connections tab ==> LAN settings ==> Look to see if a proxy has been set up, odds are it'll be on port 7070 ==> Uncheck "Use a Proxy Server for your LAN"

Great!,let's just run one more scan to be sure. Run MBAM...

Please download Malwarebytes Anti-Malware (v1.32) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

This is a great answer thread for something that is in the wild (without a browser fix apparently)
If you're here following the nfr.dll thread - (Lan works but no internet)

In case it hasnt been mentioned:
Once you've removed the malware and removed the proxy calls above,
Dont forget to:
Re-disable the file sharing (if you had it OFF to start with)
Re-enable the Windows Firewall (if you had it ON to start with)
Go into the Windows Firewall "Exceptions" Tab and deselect the references to nfr.dll

My Google query brought me here and the great info provided help me get my
system back up easily, but I wanted to add my own comments to the mix.

ps:
That autoruns tool looks like a great way to simplify cleaning out those entries as well.

thanks guys
