var _alreadyRunned = false; setTimeout(function _watcherReady() { if (window.document.readyState === "complete" && !_alreadyRunned) { avastBHO.SERPWatcherOnReadyState(); _alreadyRunned = true; } else { timer = setTimeout(_watcherReady, 1000); } }, 1000);The error is right on the line "avastBHO.SERP...." From the error it looks like the java script above using name "avast" which is the same as the AV software I use. So I am guessing that Avast JS is executing in my IE 11 and causes the problem. How do I make VS 2012 NOT to execute Avast JS?
