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.

Hello Ako,

Thank you for providing and maintaining such a great list. I've recently linked to it over at Calender of Updates, where myself and the Site Admin. would like to post in the calender there any updates to the list when they occur.

See here:

Is it possible to be kept informed when the list is to be updated and the changes that are to be made?

Best regards,

by ako (not verified) on 20. October 2009 - 5:48  (35034)

Hello RedDawn,

Thank you for your interest for this list. As the list is for looking for solutions when needed, I personally don't see informing about updates too important. However, I've been asked the same at Wilders, so we could do the following: when any major changes have been performed, I'll post a note to this thread:

Is this OK?

by ako (not verified) on 22. October 2009 - 13:10  (35246)

No reply yet. Reddawn, please contact me with the contact form.

by Anonymous on 28. October 2009 - 2:20  (35342)

Hi Ako,

I replied a couple of days ago but it must have got lost. Possibly due to this sites problems over the last few days?

I don't seem to be able to find the contact form, but will check by the thread at Wilders every now and then.


by MidnightCowboy on 28. October 2009 - 9:14  (35358)

Hi RedDawn
We did in fact lose all of the comments and some forum stuff covering a two day period after our site backup crashed. Sorry for that, but everything is back to normal now.

by Anonymous on 28. October 2009 - 13:26  (35360)

You need not to check it actively. Just register there and mark it as "follow this thread".

You'll see the contact form if you register here.

Thanks for your great list. FYI, Norton Security Scan is no longer part of the Google Pack, at least in the US.

by Anonymous on 28. October 2009 - 22:21  (35386)

Thanks, will do.

No bother, thanks for the reply.


by ako (not verified) on 29. October 2009 - 10:29  (35419)

Corrected! :)

Hi all,

Quick comment and question,

Why do you have the list repeated on "all" the pages but the comments by posters start over in their numbering?? Kind of a waste of space to repeat the list on 'each' of the pages, and sort of confusing to start post numbers over beginning at 1 on each of the pages!

Also, why is there no way to get a 'printed' version/format of the pages?

Thanks a bunch!


by ako (not verified) on 5. November 2009 - 12:58  (35929)

Good question, I'll pass it!

Startup Control Panel:
Startup Control Panel is a nifty control panel applet that allows you to easily configure which programs run when your computer starts. It's simple to use and, like all my programs, it's very small and won't burden your system. A valuable tool for system administrators!

Thanks, I'll check these.

Shouldn't FortiClient be listed as a Suite? It includes antivirus, antispyware, and a firewall.

by Brendan Bryson on 10. November 2009 - 3:33  (36290)

I vote that the name be changed to

The Best Free Security List in the World

As there is no probably about it.

Great work

by MidnightCowboy on 10. November 2009 - 9:34  (36294)

I agree with this 100% but to avoid possible legal complications the title would need to be "qualified" in some way. Even just a "?" at the end would be enough. Something like "The Best Free Security List in the World (challenge it!)" would be another option because that might induce people to post other lists we haven't seen yet containing information which might be of use here too. Whatever, I've always admired the work ako has put into compiling this list and how much is also involved with keeping it updated.

by ako (not verified) on 10. November 2009 - 10:18  (36299)

Thanks to both of you for kind words. :)
As a modest man I prefer to have the name as it is now. :D

by Brendan Bryson on 14. November 2009 - 3:37  (36591)

Hi by (no removal) do you mean that there is no uninstall option once installed?


by MidnightCowboy on 14. November 2009 - 9:30  (36600)

The use of this term usually means that a software can detect something but will not remove it or otherwise deal with afterwards which means you would need another program to complete this process.

by ako (not verified) on 14. November 2009 - 13:03  (36608)

Yes. Many commercial free programs encourage this way to by the full version.

by irwanwr on 15. November 2009 - 17:08  (36671)

Thanks for the a² information. Whether it's fully installed or portable one. I like the info. I think you have gave us very useful information to check and consider. Love you and your works.
I'll rate this post of yours to encourage you to provide people with more helpful and considerable information :)

Btw, I do think you can remove that "Probably" word on the title :D

by ako (not verified) on 16. November 2009 - 16:47  (36730)

Thanks! I'm happy if the information given here is found useful! :)

I admire the time and effort to put together such an extensive and comprehensive list.

I would like to suggest that the best and simplest security is to use a live Linux disk. Never a security problem. Never.

I love -- depending on my day and mood -- to use any of the following distros:

I'd like to know about that Net Studio USB Firewall. I've check the website link given up there. But, there's no button whatsoever to download the software. Is there anything that I've missed about how to obtain the free version copy?
Thank you.
PS: I am currently using USB Virus Scan (was Autorun Virus Remover).

by ako (not verified) on 28. November 2009 - 23:15  (37487)

The link was there :)


USB Virus Scan is not free?
