Hi...
I cannot answer re: specifically Norton apps for Mac, but...
Norton Internet Security on Windoze certainly catches most 'dataminers' which are what you are actually talking about...
Real 'spyware' is quite rare.
There are also numerous applications available for Windoze that are written solely for finding and either quarantining or deleting 'dataminer' files... I assume that there must also be others written for the Mac users.
When/If you do run an Adware/'Spyware' detection app., be cautious about how you read the results. Many of these apps are very poorly written and have as their 'definitions' rather primitive groupings that will often include every file related to a filesharing application !
If you do find some suitable application before anyone else also replies to you here, please come back and give the other Mac users a report, OK ?
p.s. Again, beware of the majority of posts and comments re: so-called 'Spyware'... The vast majority of things written about it are nonsensical misunderstandings powered by a lot of misplaced emotional 'heat' !
