Hey everyone,

Two days ago I discovered a trojan on my USB-stick. When I plugged it in on a computer at work, NOD32 Antivirus 4 came up with the following notification:

Object:
F:\AutoRun.INF

Threat:
INF/Autorun.gen Trojan

Action:
Deleted - quarantined

This notification kept popping up until I removed the stick out.

On another computer of a another firm I work for, Norton also detected a threat when I plugged it in. Norton quarantined the following files:

usb_tools.exe
usb_driver.exe
u3_sandisk.exe
sandisk.exe
kingston.exe
imation.exe

Besides the two computers at work I only use the stick on my home computer. Given the fact that the computers at work immediately detected the threat I think the stick must have been infected by my home computer. Ofcourse I would like to clean my stick but at first I am concerned about my home computer being infected. Therefore I already ran the following tests on my home computer (Windows XP Pro SP2):

Maleware Antibytes' Antimalware (scanned whole computer in safe mode) --> nothing found
AVG (scanned whole computer in safe mode) --> nothing found
Kaspersky (scanned whole computer in safe mode) --> still running

Could anyone please tell me how to verify if my home computer is infected and how I could get rid of it?

Thanks in advance!

Toni

P.S.: Kaspersky has finished and found nothing (scanned whole computer in safe mode with security level "Recommended")
