It all started when my classmate inserted a USB infected with the Nathquanglan virus. My computer got infected, so not it's plaguing my Yahoo messenger, not letting me open my task manager, and it's infected my flash disk too!!!
I don't have Norton, AVG, Avira or Avast, but the computer administrator of this computer installed "SuperAntiSpyware". It's not much help. I think there's also a Regrun running here or something like that. I'm not the computer administrator by the way, and they (the computer administrator) aren't doing anything to remove the virus.
I've tried running my computer on the safe mode and using SDFix, but RunThis.bat won't work. I've also tried to run taskmanager.reg but everytime I click it says it's not a valid win32 application. When I used the Deckard's System Scanner, the log showed that Nathquanglan is still plaguing my computer.
I don't know what to do, please help me! Every file on my computer and the USB as well is very important to me. Please, I need the help, ASAP!!!


Please don't tell me to tell the administrator about it--they're really NOT DOING ANYTHING even if I'll tell them about it.
And how do you delete the Nathquanglan virus on your USB?

Hi themadavenger and welcome to Bleeping Computer.

Try this program:
Please download Flash_Disinfector by sUBs and save it to your desktop:

* Double-click Flash_Disinfector.exe to run it.
* Follow any prompts that may appear.
* The tool may ask you to insert your flash drive, or other removable drives. Please do so and allow the tool to clean it up as well.
* Wait until the program has finished scanning, then please exit the program and reboot.

Note: Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive plugged in when you ran it. Don't delete this folder...it will help protect your drives from future infection.

See if this helps.

Hello, Starbuck, thanks for the help regarding deleting the virus on USB! I'll try it on my friend's flash disk, her flash disk is really suffering virus invasion.

Your hijackthis log is posted here.

After posting a log 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 HJT 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 member 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 HJT Team should be the only members that you take advice from, until they have verified your log as clean.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

To avoid confusion, I am closing this topic until you are cleared by the HJT Team. If you still need assistance after your log has been reviewed and you have been cleared, please PM me or another moderator and we will re-open this topic.

Thanks for your cooperation and good luck with your log.
