hi Cummins......thanks for your "warning"
images are hosted on a well know server imagefap.com ....millions of users view pages everyday ....
probably your SONIC WALL..(quite sure a free antivirus) blocked you because imagefap ( like all free services) adds a cookie that push a window pop up for advertisemnt .....
so go safe ..if you like the pics ..watch them easely ...no virus trust me
harmly suggest you to change antivirus ...if you need a cheap choice i suggest you AVG....or AVAST
