loveblueVW I think you need to use the free download program called HiJackthis.exe available I think at
http://www.spywareinfo.com/~merijn/files/hijackthis.zip
This may be the way to get rid of something that has hijacked your system.
Don't despair I got rid of mine but I did have to use things like HiJack this and then clean up the registry and then see if it had gone. It did go eventually but it took a bit of cleaning up.
I think I emptied out the cache and the cookies and looked for examples of the name of the thing that is still cropping up (the one you can't get rid of) in the registry. I opened the registry under RegEdit and searched for instances of the xxx and the other annoying hijacked applications and settings and having backed up the registry before I did it, I just deleted the xxx and the references to sex and so forth that I knew had got into the registry from visitng a site where the Internet Explorer flooded me with pop-up java windows and opened thousands of windows I had to zap almost like space invaders.
HiJack this got rid of a lot of them and then my manual one finished them off for ever. They've never come back and I have never visited a Serial number finding site again. Serves me right but that was the only way to teach me a lesson.
