I've noticed a file on an SD card named USBC(■¿, which I can't delete, rename or move. Does anyone know if this is malware and if so, how to remove it? I've tried File Assassin and Unlocker but no good. Thanks.

Hello,

 

can you upload that file for analysis?

 

You can submit suspicious files for analysis to more than one online service:

§  Jotti's virusscan

§  VirusTotal

§  VirSCAN

§  ThreatExpert

§  Metascan Online <- allows large file submissions

§  Anubis - Malware Analysis

§  Malwr Analysis Service

§  Payload Security Hybrid Analysis

§  Comodo


I would like to help you to remove malware. Let's look inside.   :busy:

But I don't know to solve all PC problems.  :smash:

i can't get it to upload to any of those. Every time I try to open it it says there's a problem with the file name, directory or syntax.

Please download MCShield from the following link:

MCShield -Official download link 
 

  • Double click on MCShield-Setup to install the application.
    Next => I Agree => Next => Install ... per installation click on Run! button.
  • Wait a few seconds to MCShield finish initial HDD scan...
  • Connect all your USB storage devices to the computer one at a time. Scanning will be done automatically.
  • When all scanning is done, you need to post a logreport that MCShield has created.

Under Logs tab (in Control Center) for AllScans.txt log section click on Save button. AllScanst.txt report shall be located on your Desktop.

=> Post here AllScanst.txt


Explanation: USB storage devices are all the USB devices that get their own partition letter at connecting to the PC,
e.g. flash drives (thumb/pen drives, USB sticks), external HDDs, MP3/MP4 players, digital cameras,
memory cards (SD cards, Sony Memory Stick, MultiMedia Cards etc.), some mobile phones, some GPS navigation devices etc.

MCShield Anti-Malware USB Tool is a lightweight scanner designed to prevent infections transmitted via removable drives (usb, external, camera cards). It's real-time protection is only real-time when you plug-in an external.

Here's the scan. McShield says the SD card with this suspicious file (Drive E) is clean:

 

 

 

>>> MCShield AllScans.txt <<<

 
-----------------------------
 
 
 
 
MCShield ::Anti-Malware Tool:: http://www.mcshield.net/
 
>>> v 3.0.5.28 / DB: 2015.11.24.1 / Windows 7 <<<
 
 
02/12/2015 19:41:58 > Drive C: - scan started (ACER ~144 GB, NTFS HDD )...
 
 
 
=> The drive is clean.
 
 
02/12/2015 19:41:59 > Drive D: - scan started (DATA ~140 GB, NTFS HDD )...
 
 
 
=> The drive is clean.
 
 
 
 
 
MCShield ::Anti-Malware Tool:: http://www.mcshield.net/
 
>>> v 3.0.5.28 / DB: 2015.11.24.1 / Windows 7 <<<
 
 
03/12/2015 10:54:57 > Drive E: - scan started (no label ~15288 MB, FAT32 flash drive )...
 
 
 
=> The drive is clean.
 
 
 
PS - I wondered if the SD card might be corrupted but CHKDSK says it's OK.
