are these safe??

i just downloaded ewido 4.0(i have the paid version)i like the new interface and some of the options.
i use netscape browser 8.1....have used netscape for years and when i ran a full scan with ewido(had the resident shield off at the time)i got @1500 of these:----mozilla.104:C:\Documents and Settings\drh\Application Data\Netscape\NSB\Profiles\hyx8lzdd.default\cookies-47.txt -> TrackingCookie.2o7 : Cleanedi

i know these are tracking cookies and probably nothing to worry about....will leaving the resident shield on automatically cleaned these with that options being checked in the shield section and is this tracking cookie issue anything to be of concern?

any help or advice would be appreciated
