please help, my system keeps crashing

Hello my name i Micke and i am in need of desprerate help,anrnt we all you say,

well my problem started about 1 and a half week ago, it all started with sudden system crashes and i thought it was just something i hade done wrong in windows, maby i hade surfed the internet and got a virus or something, well anyway, i dont ussualy use virus programs and havent used one since a few years back, since my pc has been working ok without any problems whatsoever,

i know this is not good, anyway, after i keept having these strange crashes i thought there was something wrong with the disk, so i went and bought myself a new one, reinstalled a fresh copy of windos XP 32, and everything was ok for a few hours, then suddenly i got that quick bluscreen and the computer crashed again, i then thought it was problems with my ram, i then downloaded memtest89+ and ran a memory test, actualy ran it three times, nothing turns up, my ram was working perfect, according to the test anyway,

well, i then decide to reinstall windows again, having my HD as a partian, nad keeping important files on the second pation, i then was afraid if it was a virus , witch i dident think at first , then maby i should remove that partion and all my backup files , but that was not something i wished to do, anyway, then succesfully reinstalled windows again, and decided to download Norton Antivirus software, and boom some virus came up, but that was not all, after using it today, a moment ago, something very suspicius came up thrue norton,

and i have no idea how to translate what this could be, and iam sure this could be the cause of the crashes ive been having, since the same exact file was been accesed that was running before i hade the crashes i told you about earlier,

So i took a screen dump of this warning message from Norton, and i would like som help , maby i could upload this here and you can take a look at it, and maby tell me what this could be, so i can finaly get my system safe again. as it looks now Norton seams to currently block the crash from happening witch is very nice i must say, but i still need to know what i am dealing with here, as it looks very much like someone is trying to acces my files from the internet.

 

Thank's for taking the time to listen to me!
