Hello,

This my first post here, so I'll start off by apologising if I've put this in the incorrect place. I stumbled across this forum and have found it to be very informative. As a result, I was wondering whether anyone could help me with a query I have.

Recently, my laptop became infected with Spyware Guard 2008 (hereinafter 'SG2008') and this effectively prevented my laptop from connecting to the internet (everytime I clicked on Internet Explorer 7, it suffered an error and closed). Having browsed a few websites on another computer, I was given the impression that SG2008 could be removed by running Malwarebytes Anti-Malware. I transferred Malwarebytes onto my infected laptop using a USB storage device, but not before backing up some files onto another USB storage device and some music files onto my MP3 player.

Running Malwarebytes (3 times) revealed that my laptop had been infected by a backdoor trojan/rootkit infection (Malwarebytes picked up numerous TDSS.??? files). Following the advice given on a number of websites (and on this forum), I changed my internet passwords, reformated my hard disk, and re-installed MS XP. The laptop now appears to be fine, but I was wondering whether my two storage devices and my MP3 player could have been compromised by the infection? Are they safe to use? (I have not used them since).

Thanks in advance for any help - it would be very much appreciated!

Try this
------------------------


Please insert your flash drive before you begin!

Download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that is plugged in when you ran it. Don't delete this folder...it will help protect your drives from future infection.
