A few months ago my computer was hacked because i downloaded an unsafe application to my computer. I was not using any antivirus back then other than windows defender. After realizing it i changed all my passwords, reset the windows 10 using USB, flushed DNS and reset my router. I also changed my router's password and remote control was closed all the time. I downloaded ESET internet security and till this day i am getting notifications on arp cache attacks, duplicate IP addresses on network and most of them are from my router. Is there a chance for my router to be still hacked? What should i do further? Kindly advice me.
