I have a Netgear Wnr1000v2 router. I have set my NAT to secure mode ( I don't know if that helps). Many times when I see my router's log I see lots of DoS attack: RST Scan. I think that these only occur when I use uTorrent or Tunngle. Whenever I get hit with these DoS attacks my Internet slows down significantly, then it completely disconnects.

See the latest logs:

After continuous DoS attacks you can see that the Internet eventually disconnected. I then had to reboot the router to get it work again. This happens quite often - is there something I can do? The IP address doing DoS attacks always change, so I guess there is no use in blocking these IP addresses.

Even if I am equipped with the best antivirus , anti-malware or other software, I really want to avoid getting disconnected because of these DoS attacks.
