HI!

I recently installed windows XP on my computer and transferred files over from an older computer. In the process something happened and I cannot open the "My Computer" Icon, nor can I get to my computer drives in anyway other then opening a my documents window and then typing in the drive that I want to see. Normally this wouldn't bother me, but I can click on a drive to save a file or to browse for a file without the program shutting down. I suspected i had a virus, but have run multiple virus and spyware softwares and have come up with nothing. Since this problem occured, my computer will also not completely shut down either. I am turning the computer over to my 87 year old grandmother and want it to be running smooth for her...can you please help? Based on other threads I have read I have downloaded and run hijack this and here is the report:
