codes from web pages. It’s very common that malicious codes conceal in the executable objects,
such as ActiveX, Java Applet, compressed files, and other executable files. Once downloading
these types of files from websites, you may risk bringing threat to your system. For example, an
ActiveX control object is usually used for providing interactive web feature. If malicious code
hides inside, it may occupy user’s system.
For example, if you add key words such as “sex”, Vigor router will limit web access to web
sites or web pages such as “www.sex.com”, ”www.backdoor.net/images/sex/p_386.html”. Or
you may simply specify the full or partial URL such as “www.sex.com” or “sex.com”.
Also the Vigor router will discard any request that tries to retrieve the malicious code.
