twaintec.dll

I'm trying to follow your instructions o n removing Yuckware. I have searched for xtarget.dll and had 23 entries. I was only able to delete about half of them. On the rest, when I right-click, I only have three options, copy, open and extract. When I try to extract, it copies it.
I tried to unregister the program with no avail. Any suggestions would be a great help. By the way. Ikeep getting porn movies in my favorite places.
