Is Valiselight.exe closing my Internet Explorer 7 help

 

Hi all, I was surfing ebay yesterday and IE7 kept closing down to the desktop, If I had a few windows open they all closed for some unknown reason, im using Norton Internet Security 2010 with the most updated virus definitions. I tried a registry clean and a registry defragment too, I had some 40 tracking cookies fixed when I did a full system scan yesterday, and in the past in my quaratine there was a file called "Valiselight.exe" that was a high level severity. If I leave my pc for about 15-20 minutes Norton will do something in the background like a scan or something and now and then "Valiselight.exe" will be "Blocked" but it never fully gets rid of it, would this file be closing down IE7? I have XP Home w/ SP3 and almost all windows updates as I didnt install IE8 as I dont like it. Regards GK
