Hello, today i was using my Internet Modem USB 3G stick on my laptop; i then plugged it into my computer so my brother could use the internet when "THREAT DETECTED" popped up. I've scanned my whole computer, twice- it has found nothing. I then scanned ONLY in 'my computer' the drive with my Internet USB stick plugged into it, and found the virus "FILE: E:\ResetDevice.exe INFECTION: Trojan Horse Generic16.BSXH" It says the result is 'infected' and cannot be healed or moved to the vault as it is "located on an optical drive". This was all done with AVG FREE 8.5.
I would like to know a way of removing this, and if plugging the usb back into my laptop will cause any infections to it?
(I have also scanned my laptop and found nothing on it, as it's only a week old also)

As no logs have been posted, I am shifting this topic from the specialized Malware Removal forum to the Am I Infected forum.

==>PLEASE DO NOT NOW POST LOGS<== unless a log is specifically requested.

Please describe the issues you are experiencing with your computer.

regards, Elise

Hello, its good you are concerned about this. Malware can indeed use flash drives to spread to other computers.

Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.

regards, Elise

No, it will not format the flashdrive. It will only remove malware files.

Can't you try to move all data (known safe files that is) to another drive and format the flash drive afterwards?

Yes, that is true. Please try to scan it with super antispyware.

SUPERANTISPYWARE
-----------------------------
Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.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 it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • 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 "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.
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 E:\.
  • 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.

regards, Elise

Hi All,
Alicia if you are using AVG I've had the same problem and it is NOT an infection, it was a problem with their virus definition update, they have made the necessary change today and recommend downloading the latest updates as the problem should be fixed.

Here is where I found the info regarding this problem.

I hope this helps. :thumbsup:

Grey__Wolf, thanks for sharing this with us :thumbsup:

Alicia, can you please do as suggested and update AVG to the latest definitions to see if this fixes the detection?
