use a reputable spyware finding/removal tool.
Fortunately, certain individuals have devoted a lot of time
and effort to create free software which is specifically aimed at removing these
(legal) pests from your system. One software system we tend to use
is Ad-Aware, freely available from the Lavasoft website as it is the most popular and
frequently updated removal tool. Ad-Aware functions much like any antivirus
program, so it should seem instantly familiar to most users.
Use the 'check for updates now' function to make
sure you have the latest updates. Hit the 'start' button and choose 'next' to scan
your system with the default options.
Once the scan is complete, you will be shown any
suspicious files, registry entries or cookies detected. You can now delete
or quarantine these files.
If Ad-aware found and removed malicious software,
you should empty your recycling bin and restart your computer and scan again to
make sure it is completely removed. Make sure to rescan your computer
