Hello, I have joined this forum to try to get some help for our poor computers. We think they have been infected by a virus from one of our scan discs, from an unknown source somewhere else. The virus eats up all the CPU; I actually found this forum by running a google search on the virus and found that Barry Clifford of this forum had the same problem - but I didn't understand the posted solution.

The virus comes up in the processes as liouqi.exe on our pc and luimuu.exe on my laptop but I think its the same thing as it has the same effect. (uses up all the CPU) I have downloaded GMER as that seemed to come up a lot on the posts here and found that I can 'kill' the process using this but it comes up again when I load the computer again. Also I think it may be affecting access to the control panel as since this problem started I am having trouble opening programs, but particularly the control panel, and also task manager.

One issue I have is that both these computers aren't used for internet access and don't have wireless capability so I am looking for a solution that I can move to the computer via scan disc or cdrom from a healthy computer. This is complicated by the fact that our scan discs are infected (at least we think so).

To continue our sorry tale: the house laptop which we do use for internet purposes had the free AVG anti-virus program. I downloaded the flash disinfector (found link on this forum) and tried to clean the flash drives using this. I think (fingers crossed) I may have had some success as when I plugged the first flash drive in, the AVG found the liouqi virus and I then removed it and also cleaned it using the flash disinfector. I then repeated this process with two other flash drives also (apparently) successfully. Then on the final two flash drives multiple trojan viruses were found by AVG and I removed them and cleaned the drive in the same manner. Thankfully these final two that had the trojans weren't used on the other computers.

Downloader.Generic9.ARRK
FakeAV.TZ
Vundo.KA
FakeAV.AAF
Worm/VB.7.M

Since then the house laptop has also gone completely mad. It won't shut down normally (only through a forced shutdown), everything runs slowly or just stops working randomly, and I can't do anything on the control panel or task manager which won't even open. I have opened GMER here and there is no sign of the liouqi virus so I'm not sure what has infected this computer - maybe the trojans were too powerful. I have managed to run AVG since and found nothing and also tried Malwarebytes and found nothing. It's very difficult for me to do anything fullstop. I don't know if this is more normal with modern computers but there are over 90 processes going on the house laptop according to GMER.

Anyway the bottom line is that now all 3 computers are sick in some way and we are near the final straw and don't know what to do. Any advice? :thumbsup:

Summary:

One PC - assume infected with just lioqui virus
One Private Laptop - assume infected with just lioqui virus
One House Laptop used for internet - unknown problems

Let's start with the House Laptop used for Internet. We'll start by cleaning that machine then move on to the others.

We'll start by running a few scans.

Scan for Spyware/Adware

The process of cleaning your computer may require you to temporarily disable some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware Free version and save it to your desktop.

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.


alternate download link 1
alternate download link 2
  • 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.
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.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs
---------------------------
Be sure to re-enable your AV and malware scan tools if they were disabled

SAS, may take a long time to scan
Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.

Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and 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 and exit the program.
  • Do not run a scan just yet.
  • First
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and 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 and click "Next".
  • 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" and reboot normally.
  • 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.

Note.. SAS doesn't open the registry hives for other user accounts on the system, so scans should be done from each user account.

Please post the logs from MBAM and SAS when complete. If you have any problems running either, please let me know.
