Title: HKU\S-1-5-21-....
Post by: REDACTED on March 05, 2016, 12:47:07 AM
Hi . Since thursday , when I ran a malwarebytes full scan, mbam found this thing "PUP.Optional.ConduitTB.Gen", its type : Registry key , and its location which is the most weird and i've not even found it to this day : "HKU\S-1-5-21-...-...-...-1003\SOFTWARE\Conduit . Malwarebytes says it's pup ( potential unwanted program ) , but for real . Every time I put it to quarantine and delete it, this virus ( thing ) it shows up again next day , maybe next hour after the removal .
Here is one log from Threat Scan : Malwarebytes Anti-Malware

Do any of you know how to get rid of this ? Oh , I have to mention that in this time I've reinstalled the windows as well , but only quick formatting the SSD , not the HDDs.

Ahmm.... So I've downloaded AdwCleaner and after the scan, it says something strange somehow and that is that my computer is safe ... You what mate ? Here is the message it displays after the scan : " AdwCleaner found no malicious program on your computer !"
So ? What now ? I mean, I read on the Internet about that HKU\S-1-5-21 and it says that is quite harmful  for the PC , including things like keylogger, a downgrade of the pc peformance, and so on ...
Oh, and if you ask yourself if the scan was made without any programs running in the same time , yes it was, i've closed everything from steam, chrome to my mouse/keyboard drivers.

Sorry for double posting, but even in the situation of seeing that message, I ran a scan again, of course it didn't find anything, but I pressed on Clean and i've restarted the PC. Here is the log .

No not dangerous, just a annoying toolbar
PUP.Optional.ConduitTB = Conduit Tool Bar

It is not showing in any log...  Navigate to this key and see if it present

HKU\S-1-5-21-2785295504-2673479696-1846757279-1003\SOFTWARE\Conduit

OK ... 1st of all : @Pondus : I don't understand what you wanted to say ...
2nd of all : I've used once again adwcleaner this time after a restart and a MBAM threat scan where, once again MBAM found that PUP, but this time i didn't remove it and didn't click finish from mbam so I can use ADWCleaner . Here is the log .
And finally , essexboy how can i navigate to it ? I went to regedit and then to HKEY_USERS . There i have more things ">.DEFAULT | >S-1-5-18 | >S-1-5-19 | >S-1-5-20" and of course 2 more with the name of the location but without "HKU" so at HKEY_USERS I have as well ">S-1-5-21-2785295504-...-...-1003"
It has a subfolder named SOFTWARE , but SOFTWARE doesn't contain a subfolder Conduit so... Yeah ... This is the weirdest virus or whatever it is , that i've ever had ...

Yes, it's still here... Should I reinstall the windows again, but this time erase everything on my SSD and HDD too ?

Ok . Before I do this I want to know something, if I do what you said there, is there any risk to break my computer, as you said ? And how ? :o
One more thing . I've got a little problem with the memory usage, I went to task manager and it says that "System" is using ~200MB , which is quite high because in the first/two hours it only uses around 50MB , can you tell me why ?
Title: Re: HKU\S-1-5-21-....
Post by: essexboy on March 06, 2016, 10:26:49 PM
This fix is for your computer only, use it on another computer and it may break...  Your computer is safe :)

Windows will use as much memory as possible, otherwise why have it
Title: Re: HKU\S-1-5-21-....
Post by: REDACTED on March 07, 2016, 02:08:16 PM
Yea... It says it was unable to find that registry key ...

Edit: I tried once again after a restart and there you have it : ( second one )

Is MBAM now still finding it

Title: Re: HKU\S-1-5-21-....
Post by: REDACTED on March 08, 2016, 07:14:07 AM
I'm done . It's still finding it ... :(
Title: Re: HKU\S-1-5-21-....
Post by: essexboy on March 08, 2016, 04:01:22 PM
Personally I would just ignore it as it can do no harm
Title: Re: HKU\S-1-5-21-....
Post by: REDACTED on March 08, 2016, 05:40:36 PM
Ok , i just found what is causing this problem . I went to that location in regedit and in "Conduit" there is only one subfolder : "AppPaths" which leads to an application , that one is bsplayer ... What it's quite strange, is that i've been using bsplayer for many years (more than 4 years), and only now, it appears ? MBAM as well , I'm scanning everyday my PC with it. So now, the question is, should i uninstall bsplayer ?

L.E: Or should I chose at MBAM , when it's found to be ignore always?

It depends on you really, obviously the player recreates that key on restart although it does not  actually install any files.. You could change player or just ignore it
