Hi thanks for the update,
This site does use keyword advertising but they only appear if your not logged into this site,
Some sites do the same but most do not and show the links as you describe all the time logged in or not,
You can try some of the scanners offered if you wish too ?
You haven't said what securitysuite you have installed ?
If it could be a browser add-on in any of the browsers you mentioned,
For Chrome you can check and at least make sure they do not run when Chrome is closed,
Review the Extensions section !
For Internet explorer,
Gear symbol on the top right and Manage add-ons,
