Hello!

I just did big spring cleaning and it took me a good good while, because all this comp stuff is quite new to me. I clicked "Scan only" on CWShredder and it gave me strange list of things. Spybot SD, Ad-aware, CWShredder and HijackThis already did good job. And all this remains on my comp? Or it's something ells? I don't understand this. I am new here and will appreciate if someone could explain me what is about and how can I fix it if I have to? I put here this report.
