Hi, my computer has been running fine ever since I've got it but all of a sudden I've been having tons of problems. My sister was on and I believe she messed up my system very badly. I now get all kinds of pop-ups, TagAsaurus was installed but I think I've managed to get rid of it, yet the color underneath all of my desktop icons is a strange dark blue. Also, when I sign on I get an "error loading w3d3b8f5.dll" message. I don't know what happened but I'm hoping that someone can help me out here as I have no idea what to do.
Here is my Hijack this log:
