    Take a look at GUFW http://www.dedoimedo.com/computers/gufw.html
    GUFW is a graphical front end for the Linux firewall iptables. The tutorial I linked to is pretty comprehensive and has most/all the info you should need to set up a home user firewall.
    It can be installed in most distros and all the popular ones.
    Hope this helps :)

    EDIT: Just search your software repo for it.

    Thanks for the correct link Mrk.

    Hmm without been there its hard to say whats happening o_O
    I would try rebooting and running through Mrk's tutorial a step at a time.
    Sounds obvious but have you changed the Firewall status to on {turned it on)... to my understanding changes should be saved automatically.

    1st you have to open it with password and then drag button to right side to turn it on default system rules are good enough unless you want some special rules

    link is here for new firewall

    Thankyou, I logged in with my pass, then turned it on and left it that, I made no other changes. I close it, then next time I open it, it says its off. Though, when I log in with my pass it switches to on without me doing anything.
    Thanks for the link, maybe Ill try downloading and reinstalling it.

    Actually, I just noticed this here...."Ubuntu, for instance, does not have any services listening, so the firewall is not needed." What does this mean?

    Im using Linux Mint Edition based on Ubuntu Stable Version.


    Sorry, after nearly 20 years of windows Im struggling a bit with Linux.

    On a side note, should I be using some sort of cleaner, similar to CCleaner with Linux?

    just one and put on home mode you see nothing unless you see log or listening report there you see lot of things

    how to get it is click on rules then click on listening reports you see like above mrk screenshots :)

    as for ccleaner you have bleachbit but be careful using it never remove tmp files or you get trouble

    i use bleach bit only to clean trash firefox and google chrome and flash logs thats all nothing else for save side

    also in google chrome you have this incognito mode you can check that :)

    It's been a while since I used Mint but afaik Mint will show you your current status when opening the firewall GUI.
    Weirdly enough, when you check the firewall as non-root, it shows 'Off' because you're not root.
    Check this yourself by enabling it through terminal 'sudo ufw enable' and then 'sudo ufw status'.
    It should show 'Status: Active'.
    Closing the terminal and then checking the GUI, it will still show 'Off'.
    Don't worry, it only shows you're currently non-root. It's bollocks but that's how it is.

    well rkhunter and chkrootkit but they give lot of false warnings as well no worry unless they show infected :)

    as for antivirus i dont use any now but in past i use bitdifender and avast to scan pen drives in linux antivirus is no needed unless you want to scan some external drives ....etc and share lot of files with windows pc :)

    just scan your files from virustotal online


    also google chrome is come with great sandbox which work even in linux and firefox with no script more than enough for basic needs

    to check chrome Sandbox Status

    chrome://sandbox/

    I would recommend just using iptables. This is a good website to get you started. The Arch wiki is also an excellent resource. I've just migrated from Windows to Linux too (Arch) and found writing bash scripts to import/edit and reset my rules easier than creating them through ufw/gufw.

    I would also recommend the book The Linux Command Line: A Complete Introduction. I'm about 1/2 finished with it and I think it will be the first technology book that I actually finish reading cover to cover. There's no avoiding the command line in Linux and this book is great for beginners.
