Bogus flash player download offerred?

One of the banner ads on the right is putting up a display saying a problem was detected in my flash player version and offering a link in a big yellow box to "Update Now!"

NOTE: There is no problem with my flash player version.

The link starts out with ad.z5x.net/ followed by a LONG string of gobbledygook.

This is HIGHLY SUSPICIOUS! There are any number of bogus flash player installers being offered up out there on various compromised sites which actually install malware.

This needs to be checked out, ASAP.

Unfortunately I couldn't find anything in the ad itself that identified it, or a company, or any product. It was mostly white space with a message to the effect "the video could not load". The only URL available was the download link starting as quoted in my post above.

This one really looked bogus to me.

I've not seen this bogus ad in the rotation on AVS today. Hopefully whoever was serving it up in the first place has squelched it.
