I am quite an advanced user, I only use a Windows Admin account for Admin task which makes it harder for viruses to take hold and I usually spot them.

 

However, the other day a popup launched from a website and run an Exe file from the web, it was stange in that the EXE file had the same name as much PC Machine name.  I later found it in the progam data folder and nuked it wilt Malwarebytes

 

So I have noticed some strange behaviour and wanted to know if anyone else has seen this or is it normal windows operations

 

I noticed this EXE running in TaskManager with the same name as my Windows User Account, so if my account was A1 or B2 it woulld be

 

A1.EXE *32

 

or

 

B2.EXE *32

 

 

Now it did not seem to be doing much but I have never seen it before and I am always watching my processes so I know what is usual

 

I scanned all partitions of my disk and can find no exe file of this name

 

I ran Malwarebytes on all partitions, it found nothing

 

So I went into Talk Manager and launched Resource Monitor to see what this sucker is up to, this image shows all the reg keys and files it is accessing.

What sticks out is a ZONE access which might suggest it is trying to redirect net traffic and I also saw it is accessing a file in winsxs, which is strange as that

 

I am able to zap the thing without it being recreated but when I start my PC thers is this delay and then I notice the process in Task Manager.

 

The only other system change I made was installing a print driver from Brother, not software just the native win driver.

 

Am I being ultra paranoid or is this some new Win7 feature?

 

Anyone got any ideas?

Before deleting users and running 4m tests it would be good to know whether someone else has experienced this?

OK to help others I have got to the bottom of this

 

The process that was my username WAS a virus

 

I found it by setting task manager to display more columns, I set the "image path name" to display and was then able to see where it was launched from.

 

 

You can see the behaviour described here

 

https://www.virustotal.com/en/file/12b60c4f943ec8f55a488495ead3a961d4dd608242622f9cf44597266195c37b/analysis/

 

So what it does is copy a file, e.g.

 

SRC: C:\12b60c4f943ec8f55a488495ead3a961d4dd608242622f9cf44597266195c37b
DST: C:\Documents and Settings\<USER>\Start Menu\Programs\Startup\<USER>.exe

 

 

then it runs the copied file

 

C:\WINDOWS\system32\cmd.exe /C copy /Y C:\12b60c4f943ec8f55a488495ead3a961d4dd608242622f9cf44597266195c37b" "C:\Documents and Settings\<USER>\Start Menu\Programs\Startup\<USER>.exe"" (failed)

C:\WINDOWS\system32\cmd.exe /C copy /Y C:\12b60c4f943ec8f55a488495ead3a961d4dd608242622f9cf44597266195c37b" "C:\Documents and Settings\<USER>\Start Menu\Programs\Startup\<USER>.exe""

 

 

I ran all your tools and none of them found it

 

I even ran Malwarebytes on the file and it said it was not malicious, of course I have to find the programme that creates it because at the moment there is no such file in root of C

 

All I can do is termimate the process and delete the copied file

 

According to this page

 

http://forum.bitdefender.com/index.php?showtopic=30471

 

it is also known as Mundo

 

https://en.wikipedia.org/wiki/Vundo

 

Any idead how I can get a log of what is launching it

Vundo is really old infection. I haven't seen it for years. 

 

It come through popups and all sorts of rogue software like: Sysprotect, WinFixer, WinAntiVirus, ErrorSafe, SystemDoctor, DriveCleaner, WinAntiSpyware, RazeSpyware MyPCTuneUp...

 

It creates random file names like: 

C:\WINDOWS\system32\vtsqr.dll 
C:\WINDOWS\system32\dsfvg.exe 
C:\WINDOWS\system32\rcmgkofw.exe

c:\windows\system32\ssqrroo.dll 
C:\WINDOWS\SYSTEM32\JGOSsys.dll 
C:\WINDOWS\system32\tmpA60.tmp.dll 

 

It was common infection, but then come VundoFix and that was the best cure for this infection. 

 

I found here more info to reminde me of the past.

 

But I don't think that Vundo is present here. 


I would like to help you to remove malware. Let's look inside.   :busy:

But I don't know to solve all PC problems.  :smash:
