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.

Bad link: The windows sysinternals link takes you to a random page in a sysinternals forum, not a download site.

Thanks! Removed.

I have noticed that PCtools has retired Pctools Firewall Plus and also threatfire now, It must be due to being owned by symantec. I'm using MSE as its simple and effective and I don't and haven't ever had any issues with it so no need to switch. My question is now that threatfire isn't available I was wondering what I could add or run along side MSE to replace Threatfire. I'm thinking about Immunet but I'm not sure if I do should I leave the ClamAV off and use it or should I use all engines provided by Immunet and adjust the exclusion list so they play nice. If there is something else that might run well with MSE I'm just interested in hearing a recommendation.

Thanks. That seems to be the case . But unfortunately I cannot edit the list (and who knows when the problem is corrected).

Any experience anyone?

by Anupam on 4. October 2012 - 9:55  (100243)

Don't think we should be considering this before the final release, because according to its page, it will go commercial once its out of beta.

by vodomar on 4. October 2012 - 11:56  (100245)

software has a good rating here,2817,2410274,00.asp

if it becomes trialware, we always have a symbol $ :D

by Anupam on 4. October 2012 - 12:09  (100247)

Many commercial software have a good rating. Ours being a freeware site, I think we should avoid such software. Anyways, it's a Best FREE Security List :D

by vodomar on 4. October 2012 - 13:14  (100254)

of course, but this software is more like an exception
"...Other users may want to hold off until the final release of this unusual approach to exploit protection." (,2817,2410274,00.asp)
This list should be open to innovation, even when it is paid :) (e.g. s.10.3 and 10.4)

by Anupam on 4. October 2012 - 13:22  (100257)

Many such software can be made an exception. I think it would be better to ask in the Team Forum about its inclusion here.

Many times we have avoided such software, because they were free in beta, but turned commercial when their final version was released.

by vodomar on 4. October 2012 - 13:42  (100259)

Ako should decide about s.9,9.I think that this is a new kind of security software and currently there is no free alternative :)

by Anupam on 4. October 2012 - 14:06  (100262)

OK :). Let's see what MC has to say on this :).

by MidnightCowboy on 4. October 2012 - 14:55  (100269)

IMO discuss on an individual basis in the team forum. :)
