If cleaning yourself seems either beyond your depth or likely to take more
time than you can devote, using Hijack This and posting the log in a forum
devoted to such things is the way to get the job done expeditiously. The
name is perhaps confusing, but this app basically creates a list of startup
items from your machine and logs them in a form that allows the folks in the
forums to suggest which items to disable to remove the spyware processes
that are hard to kill.
You can get the application here:
http://www.aumha.org/free.htm
and use the links in the text to the right of the download link to locate
both a tutorial in its use, and a forum in which to post your log. Don't
latch onto an existing thread--post in a new thread--the subject header you
used here should be effective, I'd think.
