Removal guide for "bestfriends.scr" AIM adware/virus.

PLEASE SEE THE UPDATED REMOVAL GUIDE FOR THE MOST CURRENT INFORMATION.

Click here for the updated guide. :)

My sis managed to get one of the family comps infected with what would appear to be a new variant to the "bestfriends.scr" AIM adware/virus.

She clicked a link in somebody's away message with a link labeled "LOOK HERE". Clicking the link would launch the default web browser and ask you to download the file bestfriends.scr.

Upon executing the downloaded file, two popups would appear which both contain banners hosted on an Angelfire site, along with setting the same AIM away message as mentioned before. Also, if one were to attempt to open either task manager or regedit on the infected machine, the windows would stay open for a mere second, and instantly close.

The installed executable could be named one of two things; either YAHOOMSG.exe, or NETSTATT.EXE, both saved in your %winroot%\system32 folder. To find out which variant you have, I'd recommend closing everything related to AIM and Yahoo Messenger, running Hijackthis, and removing EVERYTHING labeled [Yahoo Messenger] in HJT.

After you check the files and remove them, wait 10 seconds and have it scan again. Any file(s) which reappear on your list labeled as [Yahoo Messenger] is your culprit file (I have seen it labeled either "YAHOOMSG.EXE" or "NETSTATT.EXE", but your results may very).

To remove this file for good, boot Windows into safe mode, select Start/Run and type "cmd" (without quotes) into the new dialog box and hit "Ok". A DOS-like console box will open. In the box, type:

cd\ **ENTER**
cd %systemroot%\system32 **ENTER**
DEL *the filename found* **ENTER**

Note - **ENTER** = press the Enter key on your keyboard.

Once you have done this, reboot the machine back into normal mode. Run HJT again, and check and remove the infected file from the list (if the file starts reappearing in the HJT log, go back into safe mode and repeat the steps above being sure you haven't received any errors) AND the "AIM Button" .

Assuming you have followed these steps correctly, you should now be rid of the problem. If not (or you cannot find the files causing it) please post your HJT log.

Edit: Other files found which may be the cause of the problem (as taken from a HJT log):

[AOL Messenger] HQSNPFLH.EXE
[Microsoft Gina V Encryption] MSGINAV.EXE

IF YOU HAVE OTHER SPYWARE IN YOUR HJT LOG YOU MUST MAKE A NEW POST TO GET HELP WITH REMOVING IT. THIS THREAD IS FOR BESTFRIENDS.SCR ONLY!

    This entry screams to me that it's what is causing the issue:

    O4 - HKCU\..\RunOnce: [AOL Messenger] HQSNPFLH.EXE

    Check to see if that file is in system32. If so, go into safemode and delete it like I outlined in my first post.

    Hey. I was wondering if you could help me out with this. I have this problem that you were talking about but im having some problems with the removal steps. I ran hijackthis but did not see any of the files you mentioned but did notice this one "O4 - HKCU\..\RunOnce: [AOL Messenger] AOLMSNGR.EXE" looked similar to the one on jordan24s results. I posted my results below.

    Any help would be appreciated. Thank you.

    Check to see if that AOLMSNGR.EXE file is in your system32 folder (it will prolly be hidden, so make sure you have "Show hidden files" enabled in your Windows Explorer's folder settings). If so, then I'd be willing to bet it's the culprit.

    It also appears that you have quite a few other spyware related entries as well. Be sure to post your HJT log in another thread to get help with this.

    hey i did find aolmsngr.exe in the system32 folder as a hidden file. I checked it in the hijackthis and 'fixed checked' many times but it keeps coming back every time I run hijackthis.

    I also cannot run 'msconfig' to start my computer in safe mode. It is acting just like the task Manager as it pops up for a second but then goes away. Any suggestions?

    F8 gets your comp into safemode.
    you need to also manually delete that file from your system32 folder
