(long story/explanation here, if you want to get to the point, read the last few sentences) A friend of mine was using my computer recently, (EDIT: Came from yahoo) and he managed to get ad yield manager, and a delta search toolbar virus inside my computer. I went through my program files, and regedit and tried to remove them since avast wasnt helping me find them, although they were never removed. So i ran old-timers temp file remover, and the adw cleaner (recommended from you guys) but it still didnt work. So i then ran tigzy`s rogue hunter. I still had the problem. (They arent rogue files obviously) I looked up for removal tools or manual removals and i was brought to spy hunter. I did some searches, some one that was an mvp on the microsoft forums said it was safe, and avast, too, so i trusted the download. I did a scan with it, and it found many things i thought i removed manually before, so i trusted it, and bought it. (not a very smart idea) I let it run a scan, but after today i was installing the program in another computer and McAfee said it was unsafe. Later i found articles saying it was fake, and hard to remove. I ran Microsoft`s fix it tool, to remove it, but im still wondering if its there. Also, i still have ad yield manager in my computer, too even though the fake anti virus said it was removed. How might you say i remove it? Also, is spy hunter a known fake anti virus? I can post some scan logs if you want, just tell me where from. Thanks for your help!
EDIT: Requested logs attached (will be adding more)
