+第一处
+```javascript
+var _0x2bf8cc = function() {
+    var _0x393c59 = new RegExp("\\w+ *\\(\\) *{\\w+ *['|\"].+['|\"];? *}");
+    return _0x393c59.test(_0x9a4b8c.removeCookie.toString());
+};
+```
+修改成
+```javascript
+var _0x2bf8cc = function() {
+    var _0x393c59 = new RegExp("");
+    return _0x393c59.test(_0x9a4b8c.removeCookie.toString());

+第二处
+```javascript
+var _0x39e88c = function() {
+    var _0x5ea72e = new RegExp("\\w+ *\\(\\) *{\\w+ *['|\"].+['|\"];? *}");
+    return !_0x5ea72e.test(_0x3b5e10.toString());
+};
+```
+修改成
+```javascript
+var _0x39e88c = function() {
+    var _0x5ea72e = new RegExp("");
+    return !_0x5ea72e.test(_0x3b5e10.toString());
+};
+```
+第三处
+```javascript
+var _0x569c5b = function(_0x201582) {
+    this.rc4Bytes = _0x201582;
+    this.states = [1, 0, 0];
+
+    this.newState = function() {
+        return "newState";
+    }
+    ;
+
+    this.firstState = "\\w+ *\\(\\) *{\\w+ *";
+    this.secondState = "['|\"].+['|\"];? *}";
+};
+
+_0x569c5b.prototype.checkState = function() {
+    var _0x225f13 = new RegExp(this.firstState + this.secondState);
+    return this.runState(_0x225f13.test(this.newState.toString()) ? --this.states[1] : --this.states[0]);
+}
+```
+修改成
+```javascript
+var _0x569c5b = function(_0x201582) {
+    this.rc4Bytes = _0x201582;
+    this.states = [1, 0, 0];
