Windows Explorer restarts unexpectedly - HJT log included

Unknown

My Win XP Pro has a problem with Windows Explorer. When I go into explorer, it will open and function normally for a couple minutes, then it'll quit and the icons on desktop disappear and then are replaced. Any instances of explorer windows are closed. This happens pretty consistently.. basically all the time - it makes using the computer very frustrating! Any ideas?
Thanks in advance for any help that is given!!

A quick glance at your HijackThis log doesn't show anything seriously wrong.

Please run a free online scan with Kaspersky AntiVirus (works only with MS Internet Explorer 5.0 or higher).
Go to http://www.kaspersky.com/virusscanner and click the "Kaspersky Online Scanner" button (NOT "Kaspersky File Scanner").

• In the new window that opens, click the "Accept" button to accept the user agreement, install the ActiveX control, and download the program.
• When you get the Windows dialog asking if you want to install this software, click the "Install" button.
• When the "Update progress" line changes to "Ready" and the "NEXT ->" button lights up with a green arrow, click it.
• Click on the "Scan Settings" button, and in the next window select the "extended" database, and click Ok.
• Under "Please select a target to scan:", click My Computer to start the scan.

When the scan is finished, click the "Save as Text" button, and save the file as kavscan.txt to your Desktop, close the Kaspersky On-line Scanner window, and post the text in kavscan.txt in your next reply.
