Hi.

 

My router has been playing up a bit lately, cutting out etc, it could just be technical issues but it seems a little strange, is there any was to tell if it has been infected?  I guess that there is not much that can be done anyway.

 

Thanks.

FYI: that article is for a router with compromised DNS settings. An infected router is a router that runs malicious code, a router that has only compromised DNS settings does not run malicious code. Checking and fixing DNS settings is easy, checking for and removing malicious code is often very hard.
