I have Bitdefender Total Security 2014.
Recently I have been getting the message/alert "Port scan detected and blocked". I did not care about it much until I getting more especially in a specific timee. I was shocked when I saw the External IP of the attacker is from the same country where I am; so it's not a robot or virus, it's a hacker and I am his target. Can the hacker break my security and access my computer if he found an opened port?
How to block port scanning by hackers? I have heard of NMap but I am not network specialist.
If my anti-virus and firewall are not the best, what do you recommend for me? All internet is saying Bitdefender is one of the best (if not the best!). But I have asked a specialist and he said "COMODO".
What configurations should I set on my router to help regarding this problem?
Should I allow the following settings or not?
I have disabled UPnP
Wifi password encrypted "WPA2-PSK"
I have enabled: ICMP Flooding, SYN Flooding and ARP Attack but I think my internet connection getting slower!
