Hi Yared,
A analysis on your HJT logfile left these issues to fix…
We couldn’t detect any active process of a firewall on your system. Possible reasons:
(1.) You are using the windows firewall or a hardware firewall.
(2.) You are using a firewall of an unknown vendor.
(3.) You are using a firewall, but for unknown reasons it is disabled
(4.) You don’t use any firewall at all.
We recommend you to use a firewall. Download and install one or activate windows xp´s own one…
This empty entry could be fixed using HJT:
O2 - BHO: WormRadar.com IESiteBlocker.NavFilter - {3CA2F312-6F6E-4B53-A66E-4E65E497C8C0} - (no file) Neutral Unnecessary (deactivated) entry that can be fixed. LinkScannerIE.dll - LinkScanner, http://linkscanner.explabs.com/linkscann er/default.asp
This entry should be fixed definitely and apply the given anti-tojan removel instructions
O4 - HKLM..\Policies\Explorer\Run: [svchost.exe] C:\WINDOWS\svchost.exe
Must be fixed! Added by the ZAPCHAS-V TROJAN! Note - this is not the legitimate svchost.exe process which is always located in the System (9x/Me) or System32 (NT/2K/XP) folder and should not normally figure in Msconfig/Startup! Re: http://www.pcreview.co.uk/startup/svchost.exe.php
Removal instructions for ZAPCHAS: http://www.xblock.com/product_show.php?id=2854

This entry can also be fixed
O20 - Winlogon Notify: winouw32 - winouw32.dll (file missing) Unnecessary (deactivated) entry that can be fixed. winouw32.dll Filetype : Dll A Dll file (Dynamically-Linked Library) shares functions and procedures which can be used by other windows programs.
If it persists the HJT fix ,this winouq32.dll, in that case download KillBox,unzip/extract it to your desktop, from: http://download.bleepingcomputer.com/spyware/KillBox.zip
Start up Killbox and place a check in ‘Delete on Reboot’.
In the ‘Full path of file to delete’ box,copy and paste:
C:\WINDOWS\SYSTEM32\winouw32.dll
Then press the red button with the white cross.
It will then provide a window for you to confirm the delete.
Next it will ask if you now wish to reboot,select YES.
Allow it to reboot.
If it does’nt reboot automatically,reboot manually.
