Here's a Tip on USB Devices on protecting them.. :) Hope you want this... Enjoy :P

1. Check first the Auto Insert Notification setttings. Set it to "prompt user...".
2. Insert your USB device
3. Open "My Computer" after the USB loads
4. DON'T left-click, but right-click on the USB drive
5. Check: (very important)

if it displays:

Quote

Open
Explore
Search
Autoplay

then it's safe.

if it displays:

Quote

Autoplay
Open
Explore
Search

or:

or:

Open
Autoplay <-- Note that Autoplay comes after Open
Explore
Search

then your USB device is infected.

To remove it (without having to reformat your USB device):
- Of course, scan and clean it with an anti-virus software.

But to do it manually:
1. Go to Tools>Folder Options. If Folder Options isn't displayed, then proceed to step 7**
2. Go to the View tab, then enable "Show hidden files and folders", and uncheck "Hide extensions for known file types" and "Hide protected operating files" (click yes on this part)
3. Apply and Ok
4. Click the address bar
5. Type the drive letter of your USB device (example - F:\)
6. Look for suspicious files... like EXE files that has the icon of a folder, and named after the folder it is in... or VBS files in the root folder... or krag.exe and other unnecessary executables, or the folder RECYCLER. Delete those.
7. Run Notepad
8. Go to File>Save As, go to any folder you want to save.
9. Name it as "autorun.inf", then save.
10. Copy autorun.inf
11. Paste it on the root folder of the USB drive (example - F:\)
12.Confirm file overwrite.
13. Reconnect your USB device.
14. Finished. No more Autoplay.

**if there is no Folder Options, then it might have been disabled by the administrator, or your system also has already been infected.

===================================

Also dont Reboot PC (pressing restart button.) while your USB Device is inserted. it can corrupt data...

How I can do to prevent that the virus come again and infect my drive?.

Another thing, autorun and Lio appear has hidden, Read - Only and Archive and I cannot remove hidden because the option has disabled.

Thanks for the answer from antelation and excuse my english, if are something wrong.

Replying to Trap FeedBacker

I have the same problem with that lio.Vbs, my pc systems is infected, because Avira Antivir detected it:

The file 'C:WINDOWSsystem32Lio.Vbs'
Contained a virus or unwanted program 'HEUR/HTML.Malware' [heuristic]
Action(s) taken:
HKEY_LOCAL_MACHINEC:WINDOWSsystem32userinit.Exe,C:WINDOWSsystem32wscript.Exe C:WINDOWSsystem32Lio.Vbs
The fund was classified as suspicious.
The file was moved to "48b4e016.Qua"!

After I send it to quarentena, because I couldn't erease it, my script host send me a message after each reload: the archive lio.Vbs is unable in 'C:WINDOWSsystem32Lio.Vbs'
I don't want this in my startup, how I can finish it?

Ahh, my USB was infected too, but the antivir could clean it.

I had a similar problem with my sandisk drive. I went to my computer --> manage-->then go to disk management
It should see the drive there, where you can manually reformat it.
