A Guide to fix the Thumbdrive Virus; RavMonE.exe Part 2!

Filed under: Daily stuff,Every Little Thing — Jasper Mah @ 10:03 pm

Hello All! StyleZ.Blog is updated once again with the latest guide to fix your harddrive & thumbdrive viruses! In today’s guide, I will illustrate how to fix the Autoplay/Auto issue when you right click on your thumbdrive/harddrive and notice that the Auto word is present.

So what problem does the “Auto” cause if triggered or activated by the user(which is you!)?

When your hard disk or thumbdrive has been previously infected with the viruses as listed below:





or other variants of other viruses that infect thumbdrives, it will create this Autoplay function.

When you successfully remove a thumbdrive virus with a Antivirus of any brand, you will normally assume your thumbdrive/harddrive is cleaned and you could immediately access it.

Recently, with the outbreak of viruses, not many would notice it, and just ignore it, but did you know?

The virus is not completely wiped out from your thumbdrive just by simply using the general Antiviruses available in the market. Currently from testing, only Kaspersky Products such as Kaspersky Internet Security & AOL Active Virus Shield, have successfully removed this “Autorun” problem.

OH MY GOD! Then what do I do if I don’t have this antiviruses installed?

Fret not! In today’s guide, I shall illustrate how you can remove the “Autorun” problem successfully with included screenshots!

NOTE : This guide is only useful if you have confirmed your laptop is now free of virus threats, as this guide will not work efficiently if you use it on a computer still infected with RavMonE.exe or its variants as mentioned.

So without further ado . . . . . .


1. Open up your My Computer and look for Tools, Select Folder Options.

folder options


2. Go under the View Tab as shown in the screenshot below.

Folder Options 2


3. In the Advanced Settings below, make sure that the “Show hidden files and folders” is selected and the “Hide protected operating system files is unchecked”. If ask whether to proceed, choose yes. Then, choose to Apply and press Ok.

Folder Options 3


4. After you have done that, enter your harddrive that has been infected with the “Autorun” issue. At this point of time, when you are opening the drive, please right click and select Open or Explore. DO NOT at any point of time, select AutoRun or (O)Open to access the drive. Once you are in the drive, you should be looking at this as shown in the screenshot below.

Local Drive

At this point of time, follow the instructions clearly, do not delete any file unecessarily. If you do not follow the instructions and delete a wrong file, it may cause you to have a improper booting or startup that will not allow you to access your Windows.

There are important system files revealed when your local drive has the option “Hide protected operating system files” unchecked. Do not touch them!

1. Look for the file called Autorun.inf

2. It should be shaped like an orange gear with a notepad in the background as its icon.

3. Select it and delete it.

4. Check for other files such as Cn911.exe, sxs.exe, Ghost.exe, whether if they are present.

5. If those files mentioned above are present, please select them and delete them as well.

Note :

For Thumbdrives/USB Mass Storage Devices like your Harddisks, Memory Sticks, SD Cards, Mp3 Players, after you have done the steps mentioned above, you can remove your USB device, and re-plug it back to your laptop or desktop. There should be no more “Autorun” problem mentioned! Congratulations!

For Local Drives, such as your internal C:\ drive or D:\drive(not the CD Drive, the second partition you may have), you would have to restart your laptop/desktop to see the effect. Once again, congratulations!

Note 2 :

Please remember to go back to your Folder Options, and recheck that “Hide your protected operating system files” and make sure the “Do not show hidden files and folders is selected”. Since you are not fiddling/meddling around with the “Autorun” issue already, best not to make any crazy mistakes of deleting the wrong bootup file!

5. You just learned how to remove your own viruses problems involving the thumbdrives/harddrives! Congratulations! Although this is a short method, there are also other methods to deal with the “Autorun” issue if you ever encountered it. It involves registry editing. I shall share that method once I conclude the information from trying!

DISCLAIMER : This guide can be freely distributed, but it shall not be used for any commercial or illegal purposes to sell to staff/students of RP or anyone in particular, and this guide is not exactly perfect, so I apologise in advance if I have caused any confusion. At any point of time, if you have any suggestions or opinions, please reflect it into the comments section, or mail me at for any enquiries.

I understand that there are actually a few methods to solve the thumbdrive problem, so this is a suggestion from me. I welcome all other suggestions and ideas from anyone else.

Thank you for reading this guide, and I hope you have understand and enjoyed your time here.

Thank you.

  5. I think, the alternative way (if the file autorun.inf is not possible to be deleted)to remove it by editing it. Open the file autorun.inf (can use notepad). Then, you will see something like these:

    open=RavMonE.exe e
    shellexecute=RavMonE.exe e
    shell\Auto\command=RavMonE.exe e

    Delete all accept the first line [AutoRun] and then save the file. at least if it cannot be deleted, it will not run automatically.
    sorry if it doesn’t work.

  15. Hi, I followed your steps BUT i dont have any of the files that u said to delete. In other words then if i restart it should just work…Taking into considderation that if i ha to delete those files abut they aren’t there, then its the same thing ? right? When i restart and try to open my computer it works the 1st time. The second time it just freezes up. I can explore my drives though. You think the virus is still there OR is a file just corrupt ?

  32. USBC@+ë i just found out that this file, while it corrupts files, is not a virus.
    It is a hardware problem, usually common on china-made usb and mp3 players.
    Check for warranty so you can replace it.

  35. How about little.exe and autorun.inf, i think its a variant of the dropper virus a malware but i cant get rid of it on my system. It also looks like the autorun.inf is encrypted in some way and i cant get the exact location of the file being executed on my windows machine. I thought that my thumb drive was the only infected media. First i tried to delete those 2 files mention from my thumb drive and flashdrives but i wasnt able to do that with explorer. My antivirus NOD32 cant identify it as well even with the latest signature. So i tried rebooting my laptop in safe mode with ms dos command prompt then deleted those nasty files on the command prompt, resetting their attributes with -r -h -s then deleting manually. After i started my laptop in windows, there it was again on my flashdrive. So i guess i got a trojan or virus which is undetectable as of now. Im just worried since most of my work is stored on my latop. I never experience such a nasty pest. This is giving me a headache. Lol! Anyway can anybody help me on this.
