I don't get that result from rdf.org, though there seems to be an abundance of sites using those initials in one way or another. Is this happening regardless of which computer you search from, or just one?  If just one, I recommend a malware scan, first with Malwarebytes Anti-Malware and, if nothing shows up there, with the bootable Kaspersky Rescue Disk 10, which just Rescued me in a big way.  Each will take a little while to set up, and the Kaspersky disk comes as an iso that you burn to a CD, but both are free for occasional use.

 

Sometimes it seems that technology is demon-possessed.  A few years ago a church I know of got all new phones and the prefix of every number was 666. They asked for and got a different one.   :-)
