Probably the Best Free Security List in the World

Probably the Best Free Security List in the World - Page Index
1. Introduction

This article contains a comprehensive list of free security-related programs or web applications for Windows XP and later Windows PC-based operating systems. The few non-free programs on this list are included because they are of high merit (in our opinion) and lack a comparable free alternative. This list also includes links to webpages that contain security-related information.

We don't give specific recommendations on this list except for the personal suggestions of the list authors. If you are seeking recommendations then check out Gizmo's Freeware The Best Free Security Software for PC. Gizmo's Freeware also offers free personalized security advice via the Security Wizard.

We usually list a given item on this list only once, putting it where we think it best belongs. However, sometimes we list a given item more than once if we feel strongly enough that it belongs in multiple locations.

We check all links with Web of Trust. Only links that are rated by Web of Trust as green are shown as hyperlinks. Links that are rated by Web of Trust as yellow are shown as obfuscated links; in such cases copy and paste the obfuscated link to your browser's address bar, then replace [COLON] with : and [DOT] with . to change the obfuscated link into a valid URL. Links that are rated by Web of Trust as red aren't shown either as hyperlinks or obfuscated links. Links that directly link to files are shown as obfuscated links.

We usually don't test the programs or web applications on this list. We usually don't scan the programs on this list with antivirus software.

We usually don't check these keys for a given item: " Adware that may or may not be optional," " Includes software recommendations via OpenCandy," or " Nagware." We usually check key " Program that works without installation" for a given program by using only online information, not by testing the given program.

We encourage you to use the comments section below to let us know about dead links, incorrect links, links to malicious websites, links that include malicious software, incorrect or missing keys for a given item, items that could be added to the list, programs that work only on pre-Windows XP operating systems, or any other issues. You may also use the comments section to tell us about your experience with a particular program or web application. We value these suggestions and look carefully at each one.

Wuick comment. The concept is too interenting to drop away, be it free of not.

by Conan (not verified) on 24. September 2012 - 9:27  (99681)


This program is similar to CTM and RollbackRX.

The free version offers creation up to 10 snapshots.

by ako (the) (not verified) on 24. September 2012 - 15:59  (99696)

But I think 10 too little.

by ako on 24. September 2012 - 21:42  (99703)

I added it anyway.

by alexxx46 on 24. September 2012 - 10:51  (99687)

According to Bitdefender TrafficLight, 'contains viruses or other malware'.
This site is Chinese.

by MidnightCowboy on 24. September 2012 - 12:20  (99688)

This too is a false positive. URL Void returns 2/30 of which BitDefender is one, VT is clean 0/29 and Zulu returns 0/100. It would be a good idea to make a note of these links so you can check out any future queries yourself.

by alexxx46 on 24. September 2012 - 21:38  (99699)

Thank you MC.
Yet, WOT's rating of the site (3 of 5) is not very inspiring as well. All in all, there are too many caveats for an AV imo.

by MidnightCowboy on 25. September 2012 - 4:15  (99713)

You're welcome.:) This is just my personal opinion, but unless I had a spare machine for testing only, I would never trust any new program to be my main AV, irrespective of what ratings it might have. I remember well how UnThreat launched at the top of the independent testing pile, and is now down at the bottom. There are now so many well established and consistent freeware solutions available, there really is no need to risk your machine to a new product. For standard programs, AVG continues to impress with it's 2013 version and Forticlient is now up with the board leaders. For suites I personally am using ZoneAlarm Free Antivirus + Firewall with zero issues to report and of course the free Agnitum suite (Outpost) is also producing favourable reviews.

by alexxx46 on 26. September 2012 - 20:04  (99797)

I am using MS Security Essentials and EMSIsoft Emergency Kit together with MS Win 7 Firewall but I think I'll give a try to Forticlient instead of MS SE. Outpost is good and reliable, its' main con being the abundance of rather slow message boxes.

by MidnightCowboy on 27. September 2012 - 4:56  (99825)

Let us know how you get on with FortiClient. Incidentally, the old FortiClient Standard suite (AV, firewall, web filter, VPN) is still available at Softpedia.

The only thing I'm unsure about is how much it is being updated. This won't contain their new technology but for a full suite with an excellent web filter it was always a good performer.

by alexxx46 on 27. September 2012 - 19:26  (99869)

A newer version of Forticlient Lite 4.3.2 (without Firewall) can be also downloaded from via It seems to be a clean download, no crapware inside.

by AnonymousD27 (not verified) on 24. September 2012 - 7:03  (99674)

I tried that link at the bottom and Agnitum stopped and quarantined a threat and I canceled the installation. I got alerted to Adware.MarketScore!zitxnvecDX8 type trojan. Just letting you know so check it out I was going to try it out decided not to when that popped up.

by MidnightCowboy on 24. September 2012 - 8:01  (99676)

This will be a false positive. See the VT analysis results here:

by AnonymousD27 (not verified) on 21. September 2012 - 21:00  (99569)

I didn't realize that Roboscan Internet security free did so well in the recent test I was surprised where it was on the detection list. I have Agnitum Outpost security suit free and I'm happy with it. I see Agnitum way down a bit below half way was considering the switch to try Roboscan Internet security free. Any recommendations is it worth trying or should I just stick with what I have?

by Anupam on 22. September 2012 - 6:30  (99588)

Can you please share your experience with the free Agnitum suite? It looks interesting, but its site puts me in doubt. There is very little information about the suite on its site. Also, it does not seem like it's being updated.. no version information too. From its download page on CNET, the program hasn't been updated since April 2011. Don't know if they are developing it or not. This creates whole loads of doubts.

by AnonymousD27 (not verified) on 22. September 2012 - 20:56  (99619)

As you mentioned it has been a while since there was any updates to the program version. It's still version 7.1.1. I think they recently upgraded the Anti-malware engine component in the program for all versions but its only been minor changes nothing major in the last year or so and minor updates roll in when the updater runs. I am hoping they are in development of it still maybe working on the next version who knows really I haven't contacted them or inquired I guess that could happen next just to see what they have planned. It really is a good suit much better then Zonealarm free AV+ Firewall for a few reasons.
I have tried both Zonealarm's free AV+ Firewall and have gone back to Agnitum's Outpost Security Suit Free. I think Agnitum still has the better product and even though it hasn't been updated in a little while I'm sure they will soon enough. I'm happy with their HIPS and firewall component isn't too talkative if you don't want too many pop ups and can also be really talkative if you want more control over your system. The Anti-malware component is decent I believe it is a third party engine incorporated and not in house I checked and it seems its provided by VirusBuster. I haven't had any complaints with it in the time I've used it seems to offer average or above average protection. I still would recommend it even though its version hasn't changed in a bit. The HIPS is solid, the firewall is effective and the anti-malware is effective as well I haven't used the anti-spam feature as I don't have outlook or any other email clients. I do like how light it is on my system I don't find any slowdowns at all or slight pauses that can sometimes happen with other programs like Zonealarm. I look forward to seeing what they come up with in the next version I think they will keep adding to the free version as so many other providers have been as they move forward with their products. Its the minimum basic protection that one should have for their system with the threats these days I run it with Trusteer Rapport for the added online fraud protection for online banking and sensitive information. Still a good choice and I plan to stick with them. I hope that's helpful I haven't had any bad experiences with them to mention.

I am also using the Outpost Security Suite Free version. I like the firewall and, like you, also find that it does not slow down my system as much as some other options have, e.g., ZoneAlarm Free Antivirus plus Firewall. While Outpost Free does not allow you to schedule any scans, it automatically does a quick scan (about 45 minutes) at 1:00 a.m. every night. This is OK with me. I also hope they do an upgrade to the free version. I asked them about this on FaceBook, but they haven't responded yet.

by Anupam on 24. September 2012 - 7:05  (99675)

Thanks a lot. That was indeed helpful, as I think this is the first time someone has shared their first hand experience about the product here on TSA. It's good to know it's working well, and it runs light, and that you are happy with it.

I do hope that they develop it further, because from their site for the free suite, presently, it gives the impression that they do not care about this product much, and it kinda looks abandoned.
But still, from your experience, it looks like a usable product, and so if people are interested in a free suite, they can go for it.

by AnonymousD27 (not verified) on 24. September 2012 - 1:42  (99665)

I just wanted to make current and future Agnitum users aware of this, I haven't checked their site before now but since the last comment on here I decided to look into it and glad I did.
Agnitum Aquires VirusBuster technology and will provide it in house after October 1st. I guess there will be a new major update coming not sure what they have planned for the free Security Suit they offer could be the time to inquire.

by AnonymousD27 (not verified) on 24. September 2012 - 2:23  (99667)

It looks like VirusBister is closing Agnitum will be taking over...

by MidnightCowboy on 22. September 2012 - 1:07  (99575)

IMO stick with what you've got. Swapping AV's on the basis of a new set of test results make little sense, and doing so risks leaving something behind in your system that will affect the performance of new programs. UnThreat turned in similar results when it was first released, now it's at the bottom. Stick with one of the tried and trusted long term performers, of which there are plenty to choose from.

by AnonymousD27 (not verified) on 20. September 2012 - 23:48  (99529)

I guess you'll save a cell for them in case they have to do time again lol... @MidnightCowboy I bet there isn't much files left after that just about 500 false positives, they might think about a feature to cut down on that false positives maybe cloud verification or something.
