Probably the best spyware, adware, etc..ware removal tool that you can
get is a free one available from Lavasoft. You can find their homepage
You can download Ad-aware from this CNet's download site at:
You'll also want to get RefUpdate which you can find here:
Install Ad-aware first, and launch the program once installed. Then,
exit without doing any scans and install the refupdate program. Run
the refupdate program, update the datafiles (you may have to choose a
different site to download from). Once finished, exit refupdate and
re-run Ad-aware. Select, "deep scan", "scan memory" and full scan of
drive "C". Hit next.
Once it is done scanning, hit next then, right click on the list of
malware it found and select 'Check All'. Make a backup of what it will
remove, then, hit next. Voila. No more spy/mal/adware!
