It appears to be complaining about the google sponsored ads that come up at the left and top. Â I hardly pay attention to them, but they are somewhat regional and you may not see the same ones as other people. Â I'm at work here in Columbus, Ohio, but my internet is out of Phoenix so I see different ads than I see at home. Â There should be no active content, which would make the site unsafe. Â Any of our ads require you to click on them before anything happens. Â What antivirus, or security suite are you running?
I just checked the specific ad you mentioned and they are indeed regional that come up if you are in the NY/CT area. I see no active content that should be a real problem for you. One of the advertisers there might be on someone's naughty list.
