I use a free software, Superantispyware that is light years ahead of any other antispyware. Will find viruses, spyware without any conflict to your own antivirus. Finds what all other miss or unable to delete.

http://www.superantispyware.com Update and run an in depth scan. Being free, you must perform a manual update daily.

Pls., excuse my English, not my primary language.
