Windows 10: How to format "win32/installmonster" infected USB drive

Hi, after i gave my usb drive to one of my friends and took it back, i realize that my drive is write protected. I try 90% of the solutions on the web and i couldn't fix it. Now i found out that's a high alert rate virus called "Win32/InstallMonster" that the defender can't remove it.

clean possibly infected flash drives and CD-RWs

Your steps in post #1 should work for 99% of viruses that may be on a usb flash drive. However, there are a very few viruses that can infect the MBR of a drive. I would use Diskpart from a command prompt (Admin) to clean them. In the command prompt type DISKPART then, at the Diskpart prompt use the commands:

LIST DISKnote the disk number of the usb and use it in place of # in the command:SELECT DISK #
CLEAN
CREATE PARTITION PRIMARY

After this you will have cleaned the partition table from the usb and created a partition using the whole of the the available space. You can then format this partition in File Explorer.


For a CD-RW, if you right-click on it in File Explorer there is an Erase option.

 

How To Format A Write Protected Flash Memory ?

¿You already tried this one?...

Run CMD


1. diskpart
2. list disk

Then in the 3º step, put the correct number of disk in the list for the usb flash (if it's listed in disk 3, then you'll have to write select disk 3).

2. select disk #
3. clean
4. create partition primary
5. select partition 1
6. active
7. format fs=fat32
8. assign
9. exit

with that commands you will format the flash drive in fat32, if you have a large drive you can select also "format fs=ntfs" in step 7.

good luck!

 

USB Flash Drive saying not formatted..?

Hi,

I have a Memorex Poker Chip USB Flash Drive 1GB, and It shows up fine on one PC as "Poker Chip" in explore, and I can transfer files... but on my other PC (the one I'm on now..specs in profile) it's listed only as H: Removable Disk, and when I click on it, it says: "The Device is not formatted, would you like to format it now? (Y/N). Why would it be recognized on one PC, but the not the other? How come the other PC didn't need it formatted? When I click yes to format it, it says: "Windows was unable to complete the format"

I went to the BIOS and USB 2.0 is enabled. And Device Manager does list it as a Memorex Poker Chip..
