View Full Version : Nsis
With the latest Definition updates S&D wrongly flags the NullSoft Install System (http://nsis.sourceforge.net/Main_Page) by the creators of WinAmp as Spyware.
Company:
Product: NSIS Media Extension
Threat: Adware
Description
NSIS Media Extension installs in a hidden process on the computer and creates a lot of pop ups when the user is surving the internet.
The NSIS by winamp is a harmless installation program which allows you to create installers, it does nothing else.
The following is the NSIS reg enterys i have:
Windows Registry Editor Version 5.00

Your thread has been move from the Spybot-S&D (http://forums.spybot.info/forumdisplay.php?f=4) forum to the False Positives (http://forums.spybot.info/forumdisplay.php?f=16) forum so it doesn't get overlooked.
If the reference that I posted above is not related to the detection that you received, perhaps it would also be helpful if you also included the actual Spybot-S&D detections that you reveive during the scan, the Spybot-S&D version and the update level in addition to the detailed information that you did provide. To do that:
Run another scan.
When the scan completes, right click on the results list, select "Copy results to clipboard".
Then paste (Ctrl+V) those results to a new post in this thread.
Thanks

Check your scan again after tomorrow’s updates and see if the false positive has been resolved. If not, please post again.
Thanks for actively participating in the effort.
17-11-06 Update has fixed it.
I just received the identified NSIS Media Extension entry only after applying the Nov. 17th update to Spybot:
HKEY_LOCAL_MACHINE\SOFTWARE\NSIS\Media
I've run several "Search and Destroy" tests during the past few weeks with all previous updates, none of which produced this entry.
I ran the CHECK.BAT per the instructions in this thread (http://forums.spybot.info/showthread.php?t=8859&highlight=nsis+media+extension) and the logit.txt file was empty.
Here's the Spybot results report:

"Is this NSIS Media Extension entry still to be considered a false positive?"
If check.bat results were empty and you are not seeing NSIS popups then yes it is probaly a false possitive.
Could we see the contents of nsis registry key please ?
Copy the contents of the code box below into a new notepad document (not wordpad).
Click file> save as...> call it nsis.bat > file types *all files*> and save it to desktop.
regedit /e /a NSIS.txt "HKEY_LOCAL_MACHINE\SOFTWARE\NSIS"
start NSIS.txt
Run nsis.bat and post back with the text that will open
Thanks for your reply, Lonnie.
Here's the nsis.bat output:
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\NSIS]
[HKEY_LOCAL_MACHINE\SOFTWARE\NSIS\Media]
"Stub"="ns65.dll"
"InstDir"="C:\\Program Files\\Common Files\\NSIS\\"
"Clsid"="{5BACC17E-BDF7-405B-BC68-ECB506395118}"

Let SpyBot fix that item.
It is Defiantly a leftover malware item.
Will do, Lonny. Thanks again for your help!

Yes this is a serious issue, it's in fact a trojan, according to spy sweeper, I'm currently running that on a clients system at the moment, waiting for it to finish so I can finally remove this pesky pos. This turns up on every reboot after removing via a spybot scan. It just regenerates. I manually remove the registry entry and the folder x:\program files\common files\NSIS and it just regenerates after a reboot. Not a fun issue to resolve. I prefer to use just spybot and adaware pro in tandem, as I have for years, it would suck to have to move to another product over one problem that cant be resolved.
