Hello

I am experiencing very huge problem. I have 4 computers in network, and from each a lot of data is being sent to ISP name servers. Sometimes data is being sent a little from each computer in network, sometimes it is just a lot of data from one computer.

I have antivirus (Avast) and malware scan (SpyBot)

I know port 53 UDP is dns which resolves domain IP so its' needed.

Also I have read that ISP name server might have been infected.

So what is the best thing to do in this situation.

Also sometimes internet starts to lag really because of port 53
