I presently run NIS 18.6.0.29 on two pc's. One runs XP and the other Windows7 (both have identical settings on all categories). Note, I use Firefox on both devices and have set the setting to not allow tracking cookies - which does not seem to help on the W7 pc).
I notice that Quick Scans on the Windows7 pc finds and resolves tracking cookies on a fairly regular basis (as opposed to the XP pc - which is fairly rare in identifying them).
After running a test by visiting the exact same sites (down the level of pages), with both pc's, the XP pc does not discover and resolve any tracking cookie but the Windows7 pc does.
is Firefox closed on both machines when you are doing the scan? Because during a browsing session Firefox still can download cookies to interact better with the internet sites, but should remove them after you close it.
How many cookies? I'm sure there are other variables involved that would account for the difference between the two PCs. Flash setting is one that comes to mind.
During the tests described above, I made sure Firefox was closed. In fact I made sure no other application was running.
As for the type of cookies: Post Process; Quantserve; etc...
Not being overly technical, I running out of ideas and areas to check. I understand tracking cookies can be low-risk a the best of times, but I'd like to be able to correctly attribute the difference between the two devices and possible have consistent scans.
In the Flash Player Settings Manager, you need to go through the various panes and make sure that third-party content is blocked, that sites are not allowed to store Flash content, and that you delete any previously visited sites that might already have content stored. This will eliminate so-called Flash Cookies which can regenerate HTTP cookies after you delete them,
