Probably the Best Free Security List in the World


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 "Best Free" webpages (links to them are shown in the list with ) . 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.

Norton Security Scan cannot remove anything, and the Google Pack version is gone.

a suggestion:

most users, like me, would not be able to draw benefit from this great list for lack of time. So i would recommend that you take a category, decide the best one, and post it here so that one can try it.


by ako on 1. June 2010 - 5:59  (50767)

"The products for each category are listed with the best free products first (non-free products are always at the bottom of each category), as judged by me. My current choices for real-time protection on my XP desktop and Vista laptop have been marked with ►. Other noteworthy products used by me have been marked with ♦, and my favourite malware detection/removal tools with ⇒."

It is the extensive list, which makes this article popular, worthy and unique.. there is no question of shortening it :D.

by Anonymous on 4. June 2010 - 10:17  (51031)

may be we should add for Anti-phishing/malware browser plugins: - seems to be promising!?

What do you think?

by ako on 4. June 2010 - 11:47  (51039)

Seems good :) Thanks! Added.

by MidnightCowboy on 4. June 2010 - 12:23  (51046)

Is this still in closed beta or has it been released yet?

by ako on 4. June 2010 - 12:56  (51064)

soon released

Hi Ako, I have been following this list since it was started, it has been a priceless asset to me.

NortonDNS is in beta and from my experience with it, it blocks 7/10 websites on MDL (for me at least). Seems to be just as fast as any other DNS.

Cheers mate! Si vis pacem, para bellum.

by ako on 4. June 2010 - 19:41  (51281)

Thanks pal! I'll add this good hint to the list. I'm happy to hear you've found this list worth using.

Si vis pacem, para bellum! :-)

Off the wall idea, how about a section of anti-virus/malware/cloud programs that can run alongside a main antivirus? Immunet for example. Would take some time to dig up those than can do such a thing, but heck, just an idea.

Cheers mate!

by Anonymous on 10. June 2010 - 4:18  (51796)

Not a bad idea. I'll think about it :)

I added "Anti-malware (Can be run alongside with an AV):" :-)

by ako on 10. June 2010 - 10:21  (51817)

I moved Clamwin Antivirus there, as it works with other AV. Any other?

by J_L on 11. June 2010 - 2:25  (51879)
by ako on 11. June 2010 - 7:19  (51892)

:-) another good hint!

Thanks!!!! :D

A-squared Free does not seem to be available on the Emsisoft website anymore. The download link redirects to Emsisoft Anti-Malware 5, which does have a restricted free license, but is bloated nonetheless.

OperaTor changed to "Operator". The new version lacks Tor/anonymity. It's now just a portable Opera browser.

It is now Emergency...something. I'll check this.

by AlanMcAlan on 13. June 2010 - 19:12  (52037)

Under Browser Tests > Browser security (java). It seems that Jason no longer hosts the Browser Security test, thus the link is broken.

Cheers mate!

Comodo Disk Encryption

Not sure what section it would fit in, it does a little of both I think.

by ako on 13. June 2010 - 20:49  (52045)


I made new title: disk encryption

by Anonymous on 14. June 2010 - 0:07  (52060)

Oh, as far as I know, Comodo Encryption can make virtual drives as well!
