My router might be infected

So for some time whenever accesing some websites I get a pop-up windows labeled NAT Router, an is requesting my admin username and password for something calle google-analytics. I've googled this problem and I read that this has something to do with my router being infected, and that some people found the solution here. Can someone please help me?

 

I'm 99% sure it's not the computer, I have an active anti-virus an firewall, anyway i'll look for a firmware update

 

Also, is it possible that any login credentials that i use, since they get passed trough the router might be compromised?

 

Firewall is not going to keep you from getting infected. Can you post a screenshot of what you are getting. What is the manufacturer & model# of the router. google-analytics is a valid item, that is used by google for ad tracking.

 

It's a KONIG-CMP ROUTER 10

I'll try to provide a screenshot as soon as I get the problem again

 

Now the other question is, where are you located?

 

Romania, is that very relevant?

 

Yes, because location helps. Now the next question is, is this cheap Chinese router ISP provided, or is it one that you picked up?

 

Bought it from a local IT shop

 

I would ditch it and get a better router. If you can get either Netgear or Linksys products, I would do that. I just have a problem with some product that I have never heard of, and not knowing like you, how secure it is.

 

i doubt it's the router as i didn't always get that problem. Also i get the pop-ups from google-analytics and s.youtube.com

 

If you are getting pop-ups, then it is a operating system problem not the router as has previously been stated.

 

It's not the OS either, what happens is that when accesing some sites, my browser shows me a login window like the one you'd get on protected sites, requesting NAT router username and password, the request originating either from google.analytics or from s.youtube.com

 

Really can not tell you anymore than already has been covered. Suggest at this last point to get another router and see if the behavior disappears, or not.
