I dont see any more malware problems in you log so it looks like your problems lay with a file.See if this helps.


To do a Restore.

click on the Start button
select Programs
select Accessories
select System Tools
select System Restore

Start the System restore program.
Click the button next to "Restore my computer to an earlier time" and click the "Next" button.
A calendar will appear. Click on the date that you wish to restore Windows to. The box next to the calendar will show you the available restore points from that day. The ones marked "System Checkpoint" are the automatic ones that Windows XP created.
Choose the one you want, then click "Next". Don't pick a point too far back in the past,maybe one just before you started having problems -- remember, any programs you installed since your restoration point may not work anymore,so you may have to reinstall them.
Reboot your PC.
