Title: Autorun.inf
Post by: jackls on August 05, 2010, 06:24:45 PM
Each time a UDS memory stick is pluged in, an autorun.inf file is added together with DIJAMANTE\veciti.exe to which autorun refers.   Cant delete these files unless explorer.exe process is stopped and then I can erase them via cmd. prompt.    They will not reappear if I restart explorer.exe but will appear next time I remove it and  plug in again.  Avast scan of these files is clear.  I also tried malwarebytes but also gives clear report.    No entry in the registry for veciti.exe.  Veciti.exe file properties describe it as CDBurnerXP version 4.3.2.2140 and is 151040 bytes.

What is this and how can I stop the process putting the files on the memory stick?

Flash Drive Disinfector
Information and Download Flash_Disinfector.exe by sUBs from >here< (http://experi3nc3.wordpress.com/2007/05/10/flash-disinfector-by-subs/) and save it to your desktop.Note: Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive plugged in when you ran it. Don't delete this folder...it will help protect your drives from future infection.

Mirror download site, http://download.bleepingcomputer.com/sUBs/Flash_Disinfector.exe

- Also see, AutoRun.inf problems, etc. - Download and run Autorun Eater (http://www.softpedia.com/get/Security/Secure-cleaning/Autorun-Eater.shtml)

Have you tried uploading the file to www.virustotal.com and have it checked by 42 virus scanners
when you have the result copy the URL in the adressbar and post it here

Thanks for the Virustotal link Pondus.  Scan results as follows

autorun.inf see http://www.virustotal.com/analisis/4aef6afbe53b9bb3dc1f0eb7f18c3cea8693c7c1b26a71b76968357f490c670d-1280931250

Seems to be a lot of info there but I have no idea what to do to remove it.   Any pointers as to how to analyse the results?  I dont really want to use a tool if I can help it and would rather do things manually.

Many thanks

The first two are detected by Norman and the zip file by DrWeb, so you shoud be able to remove using these

Dr.Web CureIt http://www.freedrweb.com/cureit/?lng=en
How Do I Use Dr.Web CureIt!? http://www.freedrweb.com/cureit/how_it_works/
Norman Malware Cleaner http://www.norman.com/support/support_tools/58732/en-uk

Download and save to desktop, and run from there ( fully updated when downloaded )
the programs are not installed so when the work is done you can just remove by drag and drop in resycle bin

and you also have the tools suggested by DavidR

Use the Flash Drive Disinfector tool as that will place a folder on your hard disk partitions preventing reinfection of the autorun.inf file and then run the tool for for each USB that you have to do the same preventative measure.

Autorun eater may be required to remove the autorun.inf file on your USB and hard drives.
