I'm using d-link 2600U router (updated to latest firmware). My router's DNS setting keep changing and my browser redirects to adult websites and fake ads.
I scanned my computer with this softwares:
– BitDefender anti virus free
– Hitman Pro
– Kaspersky tdsskiller
– windows defender
Also scanned my mobile phone with bitdefender mobile security free
None of this softwares found any malware.
I tried factory resetting router, changed my router's password, default ip, disabled Upnp, but the problem isn't solved.
Can it be a problem with my ISP? or my PC is infected?
What should I do next?
I tested the router on another computer. Problem is still there! So there is something wrong with the router. Can a router be infected with malwares?
