You can let Ewido run again and let it fix what it finds this time.
Download and run this tool to 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.
And this one can be fixed with
hjt:
O4 - HKCU\..\Run: [LDM] C:\Program Files\Logitech\Desktop Messenger\8876480\Program\BackWeb-8876480.exe
Have you tried to rootkit scanners i posted? Did they find anything?
And i see you have no service packs installed , i would highly recommend to update windows to atleast sp1 , but preferebly sp2.
Also it seems you have no AV , have a look in our download section for some free ones.
