I'm hoping some of you super techies may be able to explain what's going on with my cookie cache, and I'm worried it may be sign of my security having been compromised.

Normally I remove most of the cookies from my browser's (Safari) cache every few days.   I'm increasingly annoyed and puzzled, btw, at how many cookies keep cropping up from sites I've never visited, and how some of these cookies pop up not long after I've deleted them, even if I haven't gone anywhere on the internet since I deleted them, but that's not what's got me really worried.

About a week ago I wanted to watch a TV show (ABC) online after it aired, and I found a site that would let me do that without having to fill out a SPAM-ready survey or set up an account or give them a credit card, etc. But I had to download a video player, which seemed to be a common one. (I think it was Flash Player, but I've since deleted it.)    Starting shortly after that (I didn't try to delete cookies for a couple days), I noticed that there are a handful of what seem to be cookies that I can't delete.   I hit "delete" and they disappear but pop right back up again -- even if I am not connected to the internet at the time.

Here are what a few of these look like:

Anyone know what the heck these are? How they get into my Safari cache when I'm not online?   And, most importantly, are they dangerous? And if so, how can I get rid of them?

Thanks,
