Malicious Programs - pp10.exe and ld12.exe

This section provides some notes on malware pp10.exe and ld12.exe registered as startup programs together with the Antivirus System PRO infection.

More notes on what I did to remove Antivirus System PRO and related malicious programs.

13. Looking at the folder, C:\WINDOWS\. sysguard.exe is not there. But there are several strange files created. See the picture below:
Antivirus System PRO pp10.exe and ld12.exe

14. Looking at running processes in the Task Manager, pp10.exe and ld12.exe are currently running. End both of them with Task Manager.

15. Deleting all 5 files listed below from C:\WINDOWS:

Name                     Size   Type                Date Modified

pp10.exe                 15KB   Application         7/4/2009 10:26 AM

ld12.exe                 28KB   Application         7/4/2009 10:24 AM

16. Running HijackThis and got 2 extra O4 (Enumeration of suspicious autoloading Registry entries) lines in the log file:

O4 - HKLM\..\Run: [sysldtray] c:\windows\ld12.exe
O4 - HKLM\..\Run: [pp] c:\windows\pp10.exe

17. Checking both of them and clicking the "Fix checked" button in HijackThis to remove ld12.exe and pp10.exe registry entries.

Some quick conclusions:

Last update: 2009.
