[My reply goes to my inbox?]

Not sure if this will resolve your issue as I don't have IMAP setup, but please check the following items:

1) Tools->Options->Preferences tab->Email Options button

Is "Save copies of messages in Sent Item folder" checked?

There is also some options by clicking the Advanced Email Options button

2) Do you have any Rules setup which filter your replies directly to your Inbox?

[Virus]

Try the applications listed by TiXer.

If that fails, make a note of the location of the files and boot up with a disk like BartPE (http://www.nu2.nu/pebuilder/). Then manually remove the files from within PE. One of my friend's had a virus which Norton and another AV could not remove for some reason. I used BartPE to remove the file manually.

Re-installing should be the last option when you have exhausted all other possibilities.
