I'm having the same issue. I can only access the site with TapaTalk. Firefox, Chrome and IE bring up the NOD32 anti-virus alert which blocks the page from loading.
No Norton huge boxes, but some of us are getting huge ESET NOD32 anti-virus alerts with blocked access to the page. I can only access SVTP with TapaTalk.
I just had the issue of not being able to access the site at all for the last 45 minutes on firefox. wouldn't load anything. back on with firefox now but still have the boxes.
Its funny it pops up for me too... I thought whole page was blocked then I saw scroll bar. It was tiny. Scrolled down and the page was loaded like normal but just with the virus stuff at the very top.
