Ewido Doesn't Find Tracking Cookies Anymore?

Hello. I just used Ewido 3.5 and it didn't find any tracking cookies. In addition, it got hung up on the file dell atapi.exe. So, I figued perhaps there is a new version of Ewido out and sure enough; I uninstalled 3.5 and have 4.0 now. Thankfully it didn't get hung up on that file, but it still didn't find any tracking cookies. When I used 3.5 before it would always find tons of tracking cookies unless I had just used Crap Cleaner (which I didn't). Do you think there is an issue or just an anomoly? Thanks.
