I don't remember entering any "funny" website and this virus warning seems to pop-up at random once every day, anyone know what it is? How can I fix it?

Object: http://mst.my03.com:8080/k.zip | [Embedded:MSEnc...

Infection: VBS:Downloader-ABT [Trj]

Process: C:\Windows\System32\wbem\scrcons.exe

    I suggest you try scanning with another AV tool, e.g. MalwareBytes (malwarebytes.com). Also, see superuser.com/questions/100360/…

  • @James Thanks, I will install malwarebytes trial, hope there won't be any conflicts with (the stupid) avast.

    You don't have to go to "funny" websites to download malware, most malware is sent through, ads

  • I have ran MBAM and disabled WSH and today that warning popped up again... Not sure what else can I do.

  • @Cristy: Try using a couple of bootable anti-virus ISO's (see the link to the SuperUser question in my previous comment) in case you have a rootkit deeply embedded in your system and your symptoms are just the tip of the iceberg.

Looks like a malicious VBScript is hooked somehow to your WMI event system - that is what scrcons.exe is responsible for - see here.

Using a free version of MBAM is a good idea, I would start with that.

You can allways check URL with Virustotal.

For the mentioned url mst.my03.com you get:

Dr.Web                  known infection source
Websense ThreatSeeker   dynamic dns

So it looks likely it is not a false alarm, it is a vbscript downloader.

One thing you can also do before you get rid of the rogue script completely is to temporarily disable WSH.

  • Thanks, I disabled WSH. Is there any drawback if I keep WSH disabled?

  • No older scripting llanguages ike VBScripts, JScript will work, BAT or PowerShell should be ok. It may be problem when you install something that uses VBScripts during install. Aug 30, 2016 at 11:48

    You may try to post your C:\Windows\System32\wbem\scrcons.exe on VirusTotal.com. There is a huge number or VBS:Downloader variants on Avast from AAA to AHK. You can also eventually block the one website superuser.com/questions/270524/… Sep 1, 2016 at 14:03

    I think this is related: la.trendmicro.com/media/misc/… but I didn't understand how to fix the issue.
