MSN Messenger offline links sent whilst my laptop is switched off!

Hello!

i need some help. my friends keep telling me i've sent them links whilst i've been offline from MSN messenger live and whilst my laptop is shut down.

the link seems to change, but one friends told me there's said 'http://very.coolstuff.info'.

i run vista. here is the story so far...

i first ran my virus checks and found errors with c:\hiberfil.sys and c:\pagefile.sys. i then found some solutions on other forums to solve these problems (or so i think). i turned off hibernation and completed disk clean up to delete file. and then went through start-run-regedit-hkey_local-sessionmanager-memorymanager and made sure my virtual memory was low, which it was. and then cleared two boxes with random words in. which seemed to leave the problem undetectable from Avira.

whilst searching forums i downloaded 'wise registry cleaner 3' which told me i couldn't deleted file ' Hkey_classes_root/msnphotoload.photouploadctl.1 ' could this be the bad file? but i couldn't locate it under the 'Hkey_classes_root' cataegory.

i have used so far SpyBot S&D, Avira Anti Vir, Adaware, Wise Registry Cleaner 3, RogueRemover, and windows disk clean up.

is there another program that i can use to help locate this msn virus/malware?

or does anybody know what it is and how to get ride of it?

if you need any additional information let me know!

Thank you so much in advance!
