Any advise how to get rid of Win32:JunkPoly [Cryp] virus?

system · June 10, 2008, 5:10pm

Recently my Avast antivirus started to detecting a virus called Win32:JunkPoly [Cryp]

The infected files are C:/gm.exe and C:/rklm.exe i always select delete but it keeps comming back.

So, any suggestions how to get rid of this virus ?

Lisandro · June 10, 2008, 9:50pm

It’s safer send to Chest than direct deleting files…
I suggest:

Disable System Restore and reenable it after step 3.
Clean your temporary files.
Schedule a boot time scanning with avast with archive scanning turned on.
Use SUPERantispyware, MBAM or Spyware Terminator to scan for spywares and trojans. If any infection is detected, better and safer is send the file to Quarantine than to simple delete than.
Test your machine with anti-rootkit applications. I suggest avast! antirootkit or Trend Micro RootkitBuster.
Make a HijackThis log to post here or, better, submit the RunScanner log to to on-line analysis.
Immunize your system with SpywareBlaster or Windows Advanced Care.
Check if you have insecure applications with Secunia Software Inspector.

I got the same virus in my PC
If you know of a free antivirus / antirootkit / antispyware that has proved to work to remove it please post it here

I’ve tried several programs so far:

avast 4.8 (avast detects and delete it but it appears again after reboot)
spybot search and destroy
sophos anti rootkit
pctools spyware doctor
XoftSpySE Anti-Spyware.
Avast antirootkit

it would be useful to run a HiJackThis scan and post the results here…

Shit! I had suspected from this file, but it seemed to be part of windows, so I let it alone. It’s the first time I’ve been told the file to have something wrong in it, and I’m not sure if it’s the mentioned junkpoly or another one. What I’m supposed to do now? There’s another thread where it says that this same file triggered a false positive

It’s running as a service.

Click “Start” > “Run” and type “Services.msc” (without quotes) then hit “Ok”.

Click the “Extended” tab.

Scroll down and find the service called Windows Action Script - Unknown owner - C:\WINDOWS\system32\scvhost.exe
Click once on the service to highlight it.

Click “Stop”.

Right-click on the service.

Click on “Properties”.

Select the “General” tab.

Click the Arrow-down tab on the right-hand side on the “Start-up Type” box.

From the drop-down menu, click on “Disabled”.

Click “Apply”, then “OK”.

Now you will want to delete the service:

Open HijackThis.

Click on the “Open Misc. tools section” button.

Click on the “Delete an NT service” button.

Type “Windows Action Script” in the space provided and click OK.

The program will ask you to reboot. Accept.

Run HijackThis! again, tick the following entry, close all other windows and click ‘fix’:

O23 - Service: Windows Action Script - Unknown owner - C:\WINDOWS\system32\scvhost.exe

Reboot into Safe Mode and delete the following file:

C:\WINDOWS\system32\scvhost.exe

That should fix it.

Thanks, with just the first steps the virus doesn’t seem to resist the cleaning anymore. I badly need my computer at this time, I will go further and delete service and file in some time when I finish my work and I can risk to mess a bit my PC
