My Kaspersky Internet Security pops up with a "malicious script" warning on IE every time I access ET. Same on more than one computer. Have accessed ET with Pale Moon/FireFox "with script blocking" and don't get the same error. Perhaps you want to check into this? Unfortunately, the popup warning doesn't last long enough for me to gather the info and report... but it has something to do with "ads".
I've been saying this for a month now. It went away for awhile and now came back again. I think there is an angry ETer out there planting viruses here.
