I recently got a trojan horse on a pc whilst my Gogear was plugged into the pc charging. After i wiped the virus off my pc i noticed my mp3 would'nt play the mp3 files n flashed a red light instead of the...


a couplle of options is to see if your PC Antivirus has an option to detect trojans etc on your USB devices. Gogear are basically usb storage devices that act as music players. you have a trojan that has changed settings in you computer. ZFirst set of steps is to eliminate the trojan from your gogear ( after re cleaning your PC). So try these steps. or you can try and reformat the gogear as well.

Instructions
    • 1 Press the "Shift" key as you insert the USB drive into your computer. Holding down "Shift" will keep the computer from auto-playing the device. Click "Cancel" to exit the auto-run if you do not hold "Shift" down long enough and the auto-play function starts.
    • 2 Open the Windows Command Prompt by clicking "Start" and then highlighting and clicking "Run." Type "cmd" (without the quotes) in the text box, and press "Enter." If you use Windows Vista, click the Windows icon, then type "cmd" in the "Search" box and hit "Enter."
    • 3 Switch the Command Prompt to your USB flash drive by typing the letter of the drive followed by a colon--for example, "F:" without the quotes--and pressing "Enter." You can locate the letter that Windows assigns to your flash drive by clicking "Start," then highlighting and clicking "My Computer."
    • 4 List the directory of files on your flash drive by typing "dir/w/o/a/p" (no quotes) into the Command Prompt and pressing "Enter." This line will tell your USB drive to compile and display a list of all files.
    • 5 Locate common viruses, Trojan horses, or malicious files in the list. Two of the most commonly reported pieces of USB malware will appear as "Autorun.inf" or "smss.exe" (both without the quotes). Unless you are using your USB to transfer a program from one computer to another, you should be suspicious of any executable file--file types ending ".exe"--that appears in your flash drive's directory. Also, as a general rule of thumb, if you see any files on your USB drive other than ones you have personally stored on it, your flash drive is infected.
    • 6 Set your USB drive to show all files so that you can delete them. Copy and paste "attrib -r -a -s -h *.*" (without the quotes) into the command prompt and press "Enter." These letters stand for "Read Only, Archive, System and Hidden File," and entering this line will tell your USB file to recognize them.
    • 7 Delete any viruses, Trojan horses, malware and suspicious files. Type "del" (no quotes) followed by a space and then the name of the file; for instance, "del smss.exe". Press "Enter" to delete that file from your USB flash drive.

USB suddenly malfunctioning on Dell TOwer


It does sound like your ports on the front might be bad. They usually connect to a seperate port on the motherboard than the rear ones, and I have seen devices short out the front ports, such as a USB music player.

You can remove the ports on the device manager, and they should come back ok, without worry. However, I doubt that is going to help the front ones. I think you have a hardware problem.

If that is the case, the easiest solution is to get a USB hub, and run a USB cable from the rear, to the front of the computer.

Uninstall usr usb maxg driver


These instructions assume Windows XP. Correct me if I'm wrong.

Insert the adapter.

Navigate to Control Panel (classic view) > Administrative Tools > Computer Management

In the Computer Management window, select "Device Manager" in the left-hand menu.

Click the + sign in the "Network Adapters" field.

If the adapter shows underneath "network adapters", follow the instructions below to completely remove it's drivers.

It's a little involved...:

1.)Go to the device in the device manager>Right-click>Properties.....

2.)Click "Driver Details" and make note of all the files listed. Once the device is gone, you need to delete those files......

Secondly, you need to find the .inf responsible for it's installation.....

3.)Go to the Details Tab, and highlight the long string....Theres a drop down at the top, it should be on "Device Instance ID" (XP, might be a tad off on the verbage)

4.)Press control+C to copy it....

Looks something like the following....

USB\VID_03F0&PID_4F11&REV_0100&MI_00

5.)Navigate to C:\WINDOWS\inf in Windows Explorer (My Computer)

6.)Press F3 and copy that string to the "A word or phrase...". Make sure, under "More Advanced Options", "Search system folders", Search hidden...", and "Search subfolders" are all checked.

7.)Perform the search. If nothing is found, take off a chunk at the end, 1 at a time, going up to the &...

1st... USB\VID_03F0&PID_4F11&REV_0100&MI_00
2nd... USB\VID_03F0&PID_4F11&REV_0100
3rd... USB\VID_03F0&PID_4F11

...etc, uintil you get a hit, with a "Driverfilename.INF". Rename that .inf file to .OLD.

7.)Now go back to the earlier part where you found all the listed drivers in the Driver Details tab, and rename them all to .something, or remove them to a safe directory outside the systemroot.....

8.)Reinstall your Drivers for the device, and plug it back in and you should have new drivers...
