by Rohit Khurana on March 2, 2008



One of our reader Kavi’s system got infected by the UST Scandal avi.exe virus, this is what he has said in the mail to


How to remove funny ust scandel.exe without any virus removal tool? or can you
provide any Vbscript for removing this virus?


As far as writing a vbscript for automatic removal of this virus, we would love to but these days we are not getting enough time to do it, but in future we will try to provide free virus removal tools made by the troublefixers themselves.

Let’s see what are the UST Scandal virus symptoms and activities and how can we remove this virus both manually and automatically.


Well we can remove this virus by a simple removal tool and through manual procedure also, lets first discuss about automatic removal tool.

Funny UST Virus Activities:

First of all this virus is not funny at all, either it may put yourself in state of embarrassment when it sends some senseless message to your friends in your yahoo messenger buddies.

It creates following files:

  • Killer.exe in c:\windows\
  • lsass.exe in c:\documents and settings\all users\start menu\programs\startup
  • xmss.exe in the root drive of all partitions and also in c:\windows
  • autorun.inf in all the partitions.
  • the main file Funny UST Scandal.avi.exe in all the partitions and
  • Funny UST Scandal.exe in c:\Windows.

Not only this, it also creates the following entries:

HKLM\Software\Microsoft\WindowNT\CurrentVersion\Winlogon\shell HKCU\Software\Microsoft\windows\Currentversion\Run\Runonce

You will find all these or some of these files if your system is infected by this virus.


Method 1: Remove the virus automatically by UST Virus removal Tool. Download it here


Method 2: Manual removal procedure.

1. Firstly you need to end process running by the virus, for this download process explorer.

killer.exe ,b.lsass.exe ,c.smss.exe

Note: close all those processes that have the same icon of Funny UST Sandal.avi.exe

2. Open Start >> Run and type “cmd” (without quotes) and press enter.
3. Above command will open up command prompt, type “cd\” (without quotes)
4. Type “attrib -h -s smss.exe” (without quotes)
5. Type “attrib -h -s autorun.inf” (without quotes)
6. Repeat step 4 and 5 for all the drives through command prompt (on the root folder)

7. Now open all your drives one by one by typing C: ,D: and so on in the address bar at the top, delete smss.exe,autorun.inf,Funny UST Scandal.avi.exe

8. Open command prompt again by following step 2.
9. Type “cd c:\windows” (without quotes)
10. Type “attrib -h -s smss.exe” (without quotes)and press enter. Type “delete smss.exe” and press enter also type “delete lsass.exe” and press enter.

Iwan BP October 14, 2008 at 3:43 am

I have my personal experience on this virus. I will help in answering the question from:
Asif, April 3rd, 2008 and sharjeel, April 26th, 2008

Before following my procedure, please run the virus remover with method 1 described by rohit, first! It will remove some of the virus component (though not all, because after thorough search in my hard drive, i still find some of them there). But the virus remover did a good job in enabling us to use the command prompt. Therefore, you need to remove manually for the rest. To use this method, you need to have some basic knowledge in how to use command prompt because you need to move from folder to folder and understand some of DOS commands.

Answering Asif question:
I had the same problem with asif as I can’t delete the virus which is:Funny UST Scandal.avi.exe. The problem is because the virus has space between it. And in command prompt/DOS prompt, you can’t delete filename with space bwetween it. I will explain how to delete it, but before that, you could check whether some of the virus components are still in ur harddrive:

In my example, i am refering to check on C: prompt and on C:\windows prompt because i find the virus components still there for me. You might need to check it in other suspected folder and sub folders yourself. Anyway, you can type the command to show hidden files which is Dir/ah/p at each command prompt as shown below:

/ah = it will show all hidden files in the folder
/p = pause the scrolling screen so you can find it slowly

For people who don’t know what DIR for, it instruct the PC to list down all the files in the current folder to your screen. But it only display non hidden files, as the virus files are hidden, you need /ah command. And some folders will contain alot of files, therefore you need to use /p command to pause at each scroll. Anyway, back to our problem:

You might find that autorun.inf, smss.exe or Funny USt Scandal.avi.exe is still shown in some of ur folder

Therefore, please follow this command in C:\> prompt:
C:\>Attrib -h -s -r funny*.exe /s
C:\>Del /p funny*.exe /s

/s = it will run the command in all folder and subfolder for the virus
/p = it will ask confirmation when you delete the file. It will prevent you to delete other files if you make some mistake in typing by asking confirmation before deleting.

Note: It will take few mins and longer if you have slower computer when using /s command. Because it search in all folder and subfolder of the specified drive (in this case, C drive). Just be patient and do other things until they finished doing their work.

By using funny*.exe, it means it will delete all executables files (exe) with the words funny in front of it such as funny.exe, funny UST Scandal.avi.exe, funny UST.exe, funnyscandal.exe, and so on.

And please do the same thing for autorun.inf. From C:\> prompt:
C:\>Attrib -h -s -r autorun.inf /s
C:\>Del /p autorun.inf /s

For smss.exe, you have to be careful. Because smss.exe located in C:\Windows>System32 is a valid windows file. So, I would not recommend using the /s command for smss.exe. Just go to C:\> and C:\Windows> folder and use Dir/ah/p on those 2 folders to see whether the file is displayed or not.

Don’t forget to repeat all of the above for killer.exe. Most of the time it already deleted by the virus remover. But sometimes you can reintroduce it again when you insert flashdisk/thumbdrive/pendrive or whatever you called the removable drive that still contain the virus.

Answering sharjeel:
I tried to remove the virus manually after I use the virus remover program mentioned in method 1 by rohit.

1. I think if you already use the virus remover, dont kill lsass.exe, as that one left in ur taskmanager is the valid one required by windows.

2. You have to use the command: Dir/ah from command prompt to find them. If you try to look for them from windows by looking at folder or subfolder, you wont find them always because some of them is hidden.

3. Look for my explanation aboce (explanation for asif)

I know asif or sharjeel might already solve their problem, but I am posting this to help other people still having the problem with this annoying virus.

One more thing, if you want to remove the virus from your flashdisk/thumbdrive/pendrive/other drive, then you need to remove it manually from command prompt. The virus remover only clear virus in your C drive/primary harddisk. When you plug in ur flashdisk/thumbdrive/pendrive/other drive, if the autorun command is active, you might re-contaminate your computer. So, first run the virus remover, second remove the virus manually again from your harddisk from command prompt, then go into the directory of your flashdisk/thumbdrive/pendrive/other drive (Might be D:, E:, F:, G:, etc) from command prompt and remove it manually.

Again basic DOS prompt is necessary for removing this virus manually. Hope my explanation will be helpful.

hi, i have only found this website now. but have a feeling that it might be too late for me.

i dont think that i have the Scandalavi.Exe virus but i do have smss.exe virus from a rogue flashstick in “c:\windows\system32 ” – yes there is a space. it blocked blocked my AV and gave itself auto permit with windows defender so it took some time for me to work out that i had it.i killed the processes and unplugged my internet hoping to restart my comp to get my AV back, scan and get rid of it.

which then leads me to my current problem. i am unable to login to my desktop, 2seconds after my comps tries to boot up to the desktop it logs out to the user login page. i have already tried all f8 – safe mode options and for each one it still logs me out.

i have also tried to boot up using the recovery console for dos access to do what you have already stated and remove from there, which brings me to my next problem the ” ” in windows environment, “c:\windows\system32 ” becomes “▼” – “c:\windows\system32▼” and i am unable to work out the dos ascii/accent for that image.

hence unable to access the folder to make it unhidden or delete the files and unable to do anything with my comp as it just logs me off.

any help would be greatly welcomed.

sir..i have tried running some anti virus before i researched for more ways to delete this virus. it was found and quarantined by both kaspersky and super anti spyware but my main concern is that my hidden files are not showing up even after trying to if i already changed the viewing of hidden file in folder options.

then i tried downloading the remover and it says…there is no funny virus running.

so i tried doing step 1…but it cant end the process of smss.exe and lsass.exe in task mgr.

then i proceed to step 2 and do it in all drives but the files cant be found.

i wish i knew what was happening to my pc why hidden files are not showing up…

any help sir? i dont really want to reboot my pc again…

thanks in advance and kudos for your site it is well recomended.
