Please download
CCleaner
Please download
Process Explorer by Systernals from
HERE.
Also download
KillBox by Option^Explicit from
HERE.
I see you have Trend Micro Internet Security and AVG free AV installed , i would remove the AVG since two AV's can cause conficts and performence issues , and AVG is free and only an AV.
Then boot up in
SAFE MODE and stay in safe mode (hit f8 when booting up), untill the entire fix is done.
Unzip
Process Explorer and double click on
procexp.exe
In the top section of the Process Exlporer screen double click on
winlogon.exe to bring up the winlogon.exe properties screen. Click on the
Threads tab at the top.
Once you see this screen click on each instance of
msupdate32.dll once and then click the
kill button.
After you have killed all of the
msupdate32.dll 's under winlogon click
OK.
Next In the top section of the Process Exlporer screen again , double click on
explorer.exe and again click once on each instance of
msupdate32.dll then click the
kill button.
Once you have done that click
OK again.
Next run
HijackThis and place a check beside each of the following:
F3 - REG:win.ini: run=C:\WINDOWS\inet20010\services.exe
O2 - BHO: (no name) - {5321E378-FFAD-4999-8C62-03CA8155F0B3} - (no file)
O4 - HKLM\..\Run: [xp_system] C:\WINDOWS\inet20010\services.exe

Delete the folder in bold , and run Ccleaner.
Double click on
Killbox.exe and then check the
delete on reboot button.
Enter the following filepath and filename into the Full path of file to delete box:
C:\WINDOWS\SYSTEM32\msupdate32.dll
Click the
red circle with the white x and allow your computer to reboot.
(if killbox doesn't reboot on its own then please reboot manually)
After your computer has rebooted please run Hijackthis again and post a new Hijackthis log.
I would also disable the windows Messenger service:
Please download
Shoot The Messenger
Download and run the small (22 kbyte) "ShootTheMessenger.exe" utility. It will display the current status of your system's Messenger Service. The button near the bottom of its window will allow you to set the service to whichever state ? running or disabled ? that you desire.
If, for any reason, you should ever choose to re-enable the Windows Messenger Service, simply re-run ShootTheMessenger to do so.
