This thread got a bit side tracked from the first post, right?
twunk_32.exe is from a worm called: W32.Blackmal.C@mm. The worm uses its own SMTP engine to email itself to all the email addresses listed in MSN Messenger, Yahoo Pager, as well as in all the files whose extensions are either .htm or .dbx. (I got this info from Symantec).
wscsvc32.exe is trojan/spyware. Try scanning these with an antivirus and antispyware programs.
If you are going to change the partitions' name from fat32 to ntfs you should use partition magic. It's safer to use and don't have to worry much about losing data. I have used it before and you can install up four operating systems with four different partitions on the same hdd.
Sorry about my earlier post; got side tracked myself. :/
Hope this helps.
