I have a machine that has been infected with spyware. Have cleaned it up but I am still having problems with the USB Ports. We have 4 ports and are using USB mouse and keyboard without issue. As soon as we plug a hard drive in or an iPod the machine reports drives corrupt and need formatting. Plug same drives into a different PC and they work as they should. Cheers.

Remove the drivers, update them again, then restart and try to use your External Drive again.

I have done that already. On reboot it re-installs the drivers and then the same issues come back.
I am wondering where the drivers are that get installed are stored? Can I delete them and download a new set?

It sounds like the driver files may be infected or damaged.

- Check that the BIOS options for USB support and emulation / legacy / USB 1.1
   are turned on.
- Use ComboFix and TDSS killer if you have not already to rule out possible rootkits.
- Do a Chkdsk /R on all local drives to rule out potential file corruption
- Perform an SFC /Scannow within the system or externally with another system to
   remedy damaged system files

If the above methods to not help it is likely you will need to perform a re-install of the
operating system. The mass storage drivers (including USB storage) are a part of the
Windows system files and cannot be removed without serious issues.

Can you post a screenshot please? does not sound like windows to me.

Try this, press and hold the Shift Key when connecting the USB device, which will disable Autorun. Release the key 20 seconds after you see a disk letter on my computer. then run a complete Online scan from here :

Let it clean-up any of the spywares / viruses found . Let us know how it went.

Thanks guys for your input. I have run Stopzilla that found some entries and removed them. If I plug a USB device in safe mode it works ok. Also when I plug a USB device in Autorun doesn't seem to activate. I do think it is virus/spyware related but this has become a monster.

I have done an in place re-install of XP Home and re-installed SP3 (the Windows disk I have is SP2 only)
I had to reactivate Windows also.

Housecall didn't find anything. I am going to download ind install Spybot next.

What would you like to see a screenshot of?
Cheers and thanks.

Tod,
Most of the new Viruses / spywares use the Autorun feature on the USB key to copy themselves, I would strongly recommend leaving it disabled.

Eitherways The Autorun program can be invoked by Right clicking on the device and Select "Autorun /Autoplay" .

However, if you have any specific reason to keep it Active, then use this MS tool which fixes problems automatically:

Hope this helps.

Regards,
Shiva

This is driving me nuts. I just had the iPod working and a USB stick. Rebooted machine and now it is failing again. I have downloaded Serviwin and found the USBSTOR driver wasn't starting. I still think it is spyware related.

Try rebooting in safe mode and see if USB device works, if it does it means that something is blocking USB devices in normal mode.

Since you have tried most of the options, try the following:

Open Msconfig : Disable all startup applications
Check Hide all microsoft Services and disable all but your Anti-virus program services.

Run Process-Mon from MS:

http://technet.microsoft.com/en-us/sysinternals/bb896645

1. Hit CTRL+A and note the system time in Processmon, hit Ctrl+A to start Auto Scroll
2. Connect the USB Disk and see which entries and processes get executed.
3. Wait for the Symptoms to show-up again
4. Hit Ctrl+A to stop the Autoscroll,note the time down.

Now, you should be able to analyze the whole set of processes going on during the timeframe.
See if any process is being triggered from any suspicious locations / registry entires and you could list them here for further discussion

Thanks mate,
Client has the drive out of this machine to copy some content off. When I get it back on Friday I will give Processmon a whirl.
Cheers.
