SOLVED!
Hello everyone. I wanted to let you know that the mystery was finally solved. My ex-boyfriend came over today and confessed everything. Months ago he sent me (over email) a file that he said contained pictures. It did, but it also contained a program that collected messenger info and emailed it to him once a week. When he emailed it to me he said to change the .ese after the name, to .exe. Dummy that I am , I trusted him and opened it. I saw the pictures and I figured that was all it contained.
Unlovedwarrior, I want to thank you because your suggestion of downloading spybot did the trick. Apparently, it was the coolwwwsearch.svcinit. I installed the hacker program again just to see, and then ran spybot again, and sure enough, it found it once more. So, thank you. Even though he confessed today, your suggestion of dl spybot bought me some days of privacy. Plus, now I am much better protected should this happen to me again.
My love life may leave something to be desired, but my computer is finally safe again! Thank you all for your help and creative and prompt suggestions.
