Windows 7: In desperate need of help!

15 Feb 2011   #1

Windows 7 Ultimate 32 Bit
In desperate need of help!

So I had this terrible attack on my computer by this nasty trojan called Cycbot.B I tried many things to solve it and eventually found a guide that recommended using Malwarebytes to clean it. I ran malwarebytes in Safe Mode and after restarting, when entering Windows I got sent to a blue screen with a IRQL Not Less or Equal Error.

In safe mode I've been able to determine that this is an error with one of my System Base Devices. I believe it is one of the memory card reader drivers.
I'm running Windows Seven Ultimate 32 bit on a Sony Vaio VGN-NW130th.
This is the hardware ID of the device:


I've installed both drivers available on Sonys support site that cover the memory card readers and it still wont work.
Troubleshooting states that the device doesn't have a driver. I've uninstalled and desabled the device and tried reinstalling the driver to no avail. Why wont the driver stick!?! I tried restarting my computer with the device disabled and still get the blue screen error.

I think my computer is pretty messed up from the Trojan / Cleanup... Is there anything I can do to access Windows regularly? I don't even use the memory card slot so I wouldnt mind completely disabling it, is there a way to do this?
Any suggestions on how to get the driver to install properly?
Also, Windows Update isn't working (I think you can't run in it safety mode though so that might be it).

Thanks so much for any support you can give me!

(oh and also, what are the chances that the Trojan could sneak onto an external harddrive if I use it to back my stuff up before an eventual system format)

To disable the driver, you would go under device manager in your control panel, find the device and right click "disable" or "uninstall". If you uninstall, you can click "scan for new hardware" and windows will locate the device and install a driver for it, or you could look it up on Google and do a manual installation.

A trojan could sneak onto an external drive, it's a tricky thing to know without knowing what exactly the behavior of the virus is... The easiest way to do it would be to copy files that you know are not infected from safe mode, and hope that it doesn't transfer.

Windows 7 Ultimate 32 Bit

Hey Liquid thx for the reply, I've tried your suggestions but the driver still wont install properly. The installation sofware says it has installed correctly but Device Manager appears with Base System Device with an exclamation next to it

You could try downloading the driver to your desktop>go to device manager>update driver software>browse my computer>have disk>navigate to where the driver is downloaded>click or double clik on the .inf file and see if it will install that way.
