    Probably, but the best option would be to make sure the machine is clean, before implementing the firewall.

    Firewalls can block inbound and outbound connections from specific programs, but if some malware is already running on the computer, there is a possibility that it has the ability to add itself as an exception to the most common firewall applications.

    Modern OS's has built-in firewall mechanism and to the some extent that can to protect. But for full fledged protection, you may buy external firewall software/ hardware. However if it is personal/ standalone , then you can install a good anti virus software to protect. However, the tag mentioned eset smart security, if you installed that one already, you have to update time to time or when it offers for patch or set it as auto update.

    What OS are you currently running? Windows has a firewall but I never put much faith in it. I have used ZoneAlarm's free firewall with good results.

    If someone already has control of your computer then all bets are off.

    Hi guys thanks for your help. Basically, i let the backdoor through my windows firewall but i now have put ESET Smart Security and their firewall after they were hacking me. There wasnt much activity since the first incident so i can't make sure if they can get in or not. I run Win 10 on this Pc BTW.

    Better uninstall eset and go for another anti virus like avast/ kaspersky. There is free version also which works fine.

    It just gives you that added protection, that doesn't necessarily mean your PC is fully secure. Not only your firewall, but also having an antivirus license does not mean your PC is bound to be fully secure. Best bet would be to operate on a private server :)

    If I were you, then I would straight away unplug the internet cable, so that the incoming threats will get buried and you can then figure out the issues. This is the the best workaround that I can think of.
