Quite frankly, if the OP is getting shitloads of malware installed then they're doing something wrong somewhere because I, and countless others, don't have any sort of problem.
You shouldn't get pop-ups when you are logged in. Set Guru to remember you and you will auto login.
If you are logged in and still getting pop-ups, the Site Feedback is the place to report it. Somewhere like http://www.guildwarsguru.com/forum/s...php?t=10270701 for example. Inde will probably read this anyway, but it's always good to post in the right location.
I use adaware to remove the malware that it finds. Apparently the site forgot me and didn't log me in automatically recently. I thought maybe the malware could have possibly come from another site , so I specifically didn't go anywhere else between the times I used Adaware, only visited GWG. It loaded the same malware, but it was when i wasn't logged in to the site.
I am sure its an excellent way to get new members by bombarding them with popups because they aren't logged in, throw out the First Impression Theory ...
