My computer is unable to shutdown properly since Monday, the 11th of February. I am turning off the power to shutdown. I've got an error "Winlogon.exe encountered a problem and needed to close." every time I log in but not sure if this is the error caused by not shutting down properly.

This is my Hijack log:

please help!

Thanks.

This is an error screen.

Hello,
The presentation of a "hijack this" log is usually a sign that someone told you to run the program due to a suspected malware problem. With that said, I would strongly encourage you to post your results in a specialized forum that is designed specifically to interpret the results of 'hijack this' logs. Sorry, I am not trained in that area.

One Shutdown issue introduced with XP Service Pack 2 was caused by the addition of "Automatic Windows Update Installation". Every time XP SP2 is shutdown, it checks for any Updates that haven't been installed yet. Sometimes, this process can cause your computer to hang if something goes wrong.

To see if this is the case, take a look for error 0x80248011 in the Windows Update logs. Specifically, look in %windir%\SoftwareDistribution\ReportingEvents.log. If you see this error, then you are going to need to do the following:

• Click "Start"
• Click "Run"
• Type in: SERVICES.MSC
• Click "Ok"
• Stop the Automatic Updates service.
• Find the software distribution folder; (c:\Windows\SoftwareDistribution) to c:\Windows\SoftwareDistribution.old
• Now go back to services and restart the Automatic Updates service
