I have a sneaky suspicion that I managed to get a virus in the past little while. My anti virus (both Avast and Malwarebytes) get disabled when trying to run a scan or anytime they try to run a standard scan. Avast has popped up warning me that there are suspicious files in my computer/windows/system32/drivers folder but the warning vanishes before I can do anything about it. I am not experiencing any redirects or slowing, but the fact that any scans are getting stopped makes me suspicious. If I checked under my network connections Avast warns me about two suspicious connections, but again, I don't know how to do anything about this.

I realize that this is super vague so if there is anything I can do to narrow it down, please let me know. I appreciate any help.

Hello Elizabeth

This infection changes settings on your computer so that when you launch an executable, a file ending with .exe, it will instead launch the infection rather than the desired program. To fix this we must first download a Registry file that will fix these changes. From a clean computer, please download the following file and save it to a removable media such as a CD/DVD, external Drive, or USB flash drive.

FixNCR.reg

insert the removable device into the infected computer and open the folder the drive letter associated with it. You should now see the FixNCR.reg file that you had downloaded onto it. Double-click on the FixNCR.reg file to fix the Registry on your infected computer.



Reboot into Safe Mode with Networking
How to enter safe mode(XP/Vista)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode with Networking using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.



RKill....

Download and Run RKill
  • Please download RKill by Grinler from one of the 4 links below and save it to your desktop.

    Link 1
    Link 2
    Link 3
    Link 4

  • Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as malicious. Please refer to this page if you are not sure how.
  • Double-click on Rkill on your desktop to run it. (If you are using Windows Vista, please right-click on it and select Run As Administrator)
  • A black screen will appear and then disappear. Please do not worry, that is normal. This means that the tool has been successfully executed.
  • If nothing happens or if the tool does not run, please let me know in your next reply

Do not reboot your computer after running rkill as the malware programs will start again. Or if rebooting is required run it again.


If you continue having problems running rkill.com, you can download iExplore.exe or eXplorer.exe, which are renamed copies of rkill.com, and try them instead.



Next run Superantisypware (SAS):

Download and scan with SUPERAntiSpyware Free for Home Users
  • Double-click SUPERAntiSpyware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the Scanning Control tab.
  • Under Scanner Options make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen.
  • Back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan.
  • Click "Next" to start the scan. Please be patient while it scans your computer.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes".
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.


Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

Please ask any needed questions,post logs and Let us know how the PC is running now.

Thank you so much for your help. I have gotten as far as running superantispyware but the scan stops in the middle and the program is gone. I tried doing the portable version and it gets stopped in the middle of the scan as well.

I don't know if you need the rkill log but here it is:

This log file is located at C:\rkill.log.
Please post this only if requested to by the person helping you.
Otherwise you can close this log when you wish.

Rkill was run on 07/09/2011 at 9:27:50.
Operating System: Windows 7 Home Premium


Processes terminated by Rkill or while it was running:

C:\ProgramData\EPSON\EPW!3 SSRP\E_S40RP7.EXE


Rkill completed on 07/09/2011 at 9:28:02.

No problem.

I ran rkill and then mbam - mbam was stopped and deleted from the computer. I tried running ESET and it didn't find anything. I tried re-downloading and re-running mbam and it was stopped and deleted once again.

One more try please.
1. Uninstall Malwarebytes' Anti-Malware using Add/Remove programs in the control panel.
2. Restart your computer (very important).
3. Download and run this utility. Mbam clean
4. It will ask to restart your computer (please allow it to).
5. After the computer restarts, install the latest version from here. http://www.malwarebytes.org/mbam-download.php
Note: You will need to reactivate the program using the license you were sent.
Note: If using Free version, ignore the part about putting in your license key and activating.
Launch the program and set the Protection and Registration.
Then go to the UPDATE tab if not done during installation and check for updates.
Restart the computer again and verify that MBAM is in the task tray and run a Quick Scan and post that log.

Thanks for your help - I tried following the steps but same problem. Mbam gets stopped after about 10 seconds and if I try to re-open it I get a file error. Incidentally, my security Avast tried to run a weekly scan and was stopped 10 seconds or so into the scan as well and was disabled. I re-enabled it.

Thanks!

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRL Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
