Just came across this information after receiving an odd message from drivecleaner.com. I was on Careerbuilder.com at the time, which doesn’t surprise me since my resume was “picked up” by some email scammers (phishing for SSN#s I guess) from that site recently. I have also been browsing EBay quite a bit lately. What exactly do I have to fear, as a consumer, from these heavy-traffic sites? I rarely click on the types of ads you have shown here, but now I NEVER will. I’ll just go directly to any website I want to visit. I work on an Apple MacBook,which I believe to be far less susceptible to viruses, and this drivecleaner showed up while I was browsing in Firefox. Any thoughts?

Then this morning, I received a second one:

Hello, I know very little about techie things, but i am on a mac and get the errorsafe messages on the careerbuilder website.

So, I thought I’d take a look, and sure enough what do I see?

Apologies for the crappy windows paint outlining but what you see there is a “mysurvey4u.com” ad on careerbuilder.com. If this name doesn’t ring a bell, I’ve already identified this as a fake front for running Errorsafe/Drivecleaner/Winfixer ads on my Errorsafe Page. Of course I have a tracer open, and what do we see? (Displayed URLs edited for clarity)

Now I”m mostly guessing here, but it looks to me like CareerBuilder is hosting this creative themselves using 24/7 RealMedia’s Open Adstream adserver. Looking at the URL I’m going to guess that the creative for MySurvey4U was supplied by “BurnAds” — which from their website appears to be yet another online advertising/marketing/ad-network.

If you happen to have a contact at CareerBuilder they could probably use a little education on ad-safety.
