To only call this a firewall is really an injustice. Online Armour Free is almost a full security suite in itself. What I mean by that is it has actual HIPS features and virus definitions and updates and everything!
With Online Armour and a full fledged antivirus program you will be completely and totally protected from all the nasty & ugly's. I often used two antivirus programs together and a firewall until I discovered Online Armour Free here On SnapFiles. Now I only have an antivirus and this program, but feel more secure than before. It's really that good.
My PC boots quicker because it doesn't have to load as many programs at start up. I have more available ram than before and less taskbar clutter. This is all good stuff!
I'm more than pleased and will always keep this on my short list of security favorites. It is truly much more than just a firewall.
I used to me a diehard Zonealarm fan.. for years. Then things changes there and not for the better. I went with Microsoft Security Essentials and a number of other free firewalls - I can't even remember all the ones I tried. I have to say that Online Armor has surpassed my expectations. It did not slow down my PC at all. I do have 4 megs of ram and if you're finding it's slowing down your system you really need to upgrade your system. I have it paired with Avast free antivirus and the two programs so far are living together harmoniously.
This is good software that happens to be free. It is very light on System resources (exactly 7 MB ram and 3 cpu peaks only) It blocks keyloggers and always warns you if software tries to do something suspicious but you only get alerts if you install new software and the vast majority of software is automatically allowed (because they're trusted vendors) so you don't get annoying pop-ups!
Now to answer some other reviewers criticisms: "my computer takes longer to boot" Well then you have a lower spec processor/ram! Online Armor 6 Free updates itself every boot or every 6-8 hours If this is a bad thing you don't want to be protected! "the site matou sec..." This site doesn't even rate Emsisoft's product despite it's free! Suspiciously the site rates Comodo's products above EVERY other including Bitdefender and Kaspersky PAID solutions which means I never gonna believe in their reviews!... I used ZoneAlarm Free but after seeing that it never updated (even manually!!!) and gave the same number of blocked IP packages every day realized that this information was totally bogus and I don't like to be deceived by a security product! I recommend this firewall after testing ALL free firewalls! This one was the winner.
