(1/3) > >>

sunnyday:
my USB thumbdrive-1 name was auto changed to "pendrive" . I suspect it was caused by some virus , not sure in thumbdrive-1 or in computer .
 After copy some files from thumbdrive-1 to thumbdrive-2, same problem happen =>  now my thumbdrive-2  has been auto renamed as " pendrive"  .
I tried the 3rd thumbdrive by copy files from thumbdrive-1 , now the 3rd thumbdrive has been auto renamed as "pendrive" .
Something must have gone wrong , please advice how to resolve this . thanks !

If you already have Malwarebytes be sure to update it before running the scan!

Download Malwarebytes' Anti-Malware (MBAM)

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to the following:

* Update Malwarebytes' Anti-Malware
* Launch Malwarebytes' Anti-Malware

* Then click Finish
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform quick scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy and Paste the entire report in your next reply.

Extra Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts, click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.

I'd like to note: if we are talking about the hardware identification- rather then volume labels, I've seen this happen twice with very old thumb drives; rather then identify, for example, as a SanDisk Cruzer Mini, it identified as a "SanDisk Pen Drive". This usually happens as the drive itself is failing.

If however this is the actual volume label it's certainly malware.

I'm curious to see if any malware is found. I'm leaning towards no.... but then you never know.

I have run the MBAM on following :
a) scan the computer
b) scan the tumbdreive-3 ( which is a brand new 2G tumbdrive) nb. the original name of this drive was "Toshiba" 
c) scan the tumbdrive-2 ( this is also a new 2G tumbdrive ) nb. the original name of this drive is "tumbdrive"
d) scan the tumbdrive-1 ( this is an old 128M tumbdrive) nb. the original name of this drive is "tumbdrive"
