Win32 sality AP
« on: February 26, 2008, 07:03:21 PM »
Hi Mohammed Aslam,

W32/Sality-AL is a prepending virus that also acts as a keylogger.

W32/Sality-AL includes functionality to send notification messages to remote locations.

When W32/Sality-AL is installed the following file is created:

<System>\syslib32.dll

The file syslib32.dll is detected as W32/Sality-H.

Download hijackthis from here:
http://www.trendsecure.com/portal/en-US/tools/security_tools/hijackthis/download
run and save a log file txt and then attach to your next posting,

Sys.ini can confirm also that Sality has taken over.

Edit it and remove these lines:

[MCIDRV_VER]
DEVICE=871703soflv19069
__h=18
__dr=22

Hi Mohammed Aslam,

I see nothing out of the ordinary there, we will have a more profound look with this:
Download Deckard's System Scanner at http://deckard.geekstogo.com/dss.exe to your desktop.

- Close all applications and windows.
- Double-click on DSS.exe to run it, and follow the prompts.
- The scan may take a minute. When the scan is complete, two text files will open - Main.txt and Extra.txt

Note: When running DSS, some firewalls may warn that sigcheck.exe is trying to access the internet - please ensure that you allow sigcheck.exe permission to do so. Also, it may happen that your Antivirus flags DSS as suspicious. Please allow the Deckard's System Scanner to run and don't let your Antivirus delete it. In this case, it may be better to temporary disable your Antivirus.

Post the main.txt and extra.txt from the C:\Deckard\System Scanner folder as an attachment to your next reply,
