Not sure if viral or what

[Yerasimos]

Hiya,

I have run into an issue that I havn't seen before and am unsure as how to tackle it,  When out look starts there is an error message and it seems the emails are not being sent but they are, the recipient is recieveing them, also some downloaded music is being deleted, that is all I know for now,  I have tried running spysweeper, panda anti and rolling back the system restore but it hasn't worked.  Does anyone know if there is a virus out there that causes these issues or if there is something else wrong.  Thank you to everybody for any help you can give and have a great day. :-?

I don't know what to do for Outlook, but as for the music:
If its downloaded from KaZaa, it may have a string of programming in it.
Therefor, the piece of music is recognized as Spyware/Adware since it is from KaZaa. Running your antispyware/adware and possible your AV scanner may be the cause of the disappearances.
