Update:Pop up advert problem (fixed)
It has come to our attention that one of the advertising agencies that supplies adverts for our website has been careless and was running an advert which causes multiple pop-up windows and/or virus false-alerts.
We are obviously extremely annoyed at the advert-agency for allowing this to happen. We know how annoying pop-up adverts are, and explicity told them they must not run them. We have now fixed this problem by disabling ALL adverts from this advert agency. All their adverts and code have been removed from our site in response, so the problem should no longer occur. If you are still seeing pop-up windows at runescape.com then try rebooting your computer. If the problem still persists then let us know, remembering to tell us the name of the advert causing the problem.
Also I'd like to reassure players that if they saw a warrning about a virus called "JS/NoClose" they do not need to worry too much. This is not a real virus, but rather a way of opening many pop-up windows. It does not cause any other damage or problems, and I believe all you have to do to erase it is reboot your computer. So if you are seeing these warnings, please reboot your machine. If the problem persists after reboot then let us know.
I sincerely apologise for this. Like I say I'm severely disappointed with the advert-agency for doing this. I'll do what I can to make sure it doesn't happen again.
