Regedit and msconfing closes by themselves

hi guys first of all i'm going to introduce myself, as i'm new here. i'm paulo,31 from portugal. this is the problem i get, maybe malware or virus related seriously don't know.

when i open them they close after a few seconds. i also cant access windows security center or windows firewall or add/remove programs cuz it gives me this weird rundll32.exe. kaspersky internet security 6.0 tells me i have a virus and it tells me av.exe itself (kis main file has a virus too). i thought formatting the pc would solve this eventually, but the virus remains, it causes my computer to crash with BSODS (blue screens of death), when i try to execute a programs it says either the file is corrupted and has been modified or it crashes.

i have the weirdest errors like when i start windows xp it logs in and then automatically it logs off after a few seconds. i dont know what kind of virus this is, but it seems kaspersky 6.0 doesnt seem to be able to delete. once i start kaspersky it goes crazy with reports of virus and it says i have to delete lots of files, even windows system files, when i dont delete the file it asks to delete another one and so on, lots of files with virus. i ran ewido and online antivirus like trend micro and kaspersky and they detected nothing, nor virus or spyware. somebody please help, i'm going crazy here.

i'll post 2 of my most recent my hijackthis logs



hope you guys can help me out

thanks in advance
