Another Computer Problem...

I thought our computer are totally recover with the virus but right now? i dont understand because everytime i surf the net, the blue screen showed up and it says the file been corrupted or something. I check the reports of our new Anti-Virus "the Kaspersky" and i didn't see any virus in there. Hmmm i was wondering maybe because some of the program are not properly installed and i need to check that to make it sure our computer is okay. Everytime i see that blue screen, i dont have any choice, i need to restart our computer. Its very irritating everytime it showed up. I checked already the add/remove programs at the control panel but i didn't see any file that is not finished installed. I dont know what to do, i dont want to bring our computer again at BestBuy because maybe it will take again for couple of days to fix the computer and we need to pay it again. Isn't that frustrating? Oh well, i need more patience and need to check all the files we have and check if they are properly installed or not. Will see what happen after few days :-)
