Hi, i am using eset internet security with firewall in interactive mode. I also run mbam exploit protection with it. When ever eset block a port scan attack my internet slows down to 1/4 th of its original speed. I could see the log in eset log list that the port scanning attack has been successfully blocked . But i don't know why my internet slows down after the attack ! I have to disconnect from the internet completely and reconnect to get the normal downloading speed again. I scanned my cpu with mbam(rootkit scan) enabled, hitman pro and eset IS and no detections have been found in my system . How do i prevent my internet from getting slowed down after a port scan attack ?
