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.

I'm glad if you found the list useful! :-)

by Anonymous on 4. April 2010 - 19:13  (46961)

This is truly a Great list of Software,I use lots of these! I'm a IT Professional, its my second job.
Lots of the security software,and other tools are useful! I have issues sometimes though,with the way people think of software.I've heard many people say well if its "Free" it doesn't always work! That has to be one of the BIGGEST LIES I've ever heard.Many free tools in dozens of software areas can be better and Software that is not free.It's all about Advertising,and Promotion

The other issue is,how people use the computer! All these programs above are great some work better for some than others! Sometimes people use too many of them,once again it becomes more of a "It gives you a good feeling" you're protected or being more efficient and then people's computers start running slow and then they use something else. etc etc! On and on!

I don't even use Anti-Virus,I do regular scans using different tools,and I'm a downloader...But I know how to use my pc,the problem we got here is people being un-educated and spending money when they don't need too.But Gizmos is Awesome and how it informs people! I just think more people need to focus on really understanding software,and 90% of these companies get their money from people who don't want to google or ask a professional,they read blogs and there you go.

I guess its my view on it.

Anyway Great site and Staff

That's sad to hear. On my malware testing machine it has worked flawlessly. Hopefully you had disk image available?

by Anonymous on 16. April 2010 - 18:54  (47795)

Well, I'm speechless! There's nothing else like this the world. I reckon a medal or some certificate of honor is overdue for Gizmo and his team and all who help. This has developed into a stupendous work, seemingly without end. Where would we be without it? And there's a huge bond of trust between us folk and Gizmo and his team, whose honesty and integrity are without question! It's so refreshing to find such open honesty on the Internet riddled with thieves of all types and sizes... Congratulations Gizmo and Company! Bob.

Thanks for the kind words Bob. Ako puts a huge amount of time into expanding and maintaining this list, and still finds time to do other things for the site as well. It's always nice when the effort is appreciated.

Clam Sentinel's home page is at on source Forge. Sentinel was originally designed for Windows 98 and Windows 2000 machines, but it also works well on XP, Vista, and Windows 7 machines as of today, April 16, 2010. It provides basic file protection, but you should probably use it with an Antispyware/Antimalware program like Windows Defender (real-time) or the free version of SuperAntiSpyware/Malwarebytes, or a behavior blocker like WinPatrol or Threat Expert. I currently use it with Windows Defender, WinPatrol, SpywareBlaster and the free Windows Firewall on my Vista machine. I download all Windows patches, keep ClamWin updated hourly, and set ClamSentinel set to scan in real-time for the 50 most dangerous file extensions. Spyware Blaster is updated once or twice a month and WinPatrol warns me about autostart/hidden files. I do a daily scan with ClamWin. My little security setup seems to provide pretty good protection--all for no cost.

Wondershare time freeze link doesn't work for me.

by Anonymous on 24. April 2010 - 6:34  (48323)

Due to site politics direct links to executable files and non-green WOT-sites are forbidden. In such cases replace [dot] with . and the link will work.

Everyone needs a hero. Ako you are my hero! Thank you so much for the excellent work you did on this list. I don't know if you make any money doing this, but it is worth paying for, and you provided it for FREE! This is going above and beyond the call of duty. Words can not describe how great this list is, even if I disagreed with everything in it. YOU RULE!!!

by ako on 1. May 2010 - 8:21  (48884)

:) Thank you very much for your kind words. This is just a hobby, but I'm really happy if people feel it helps them to secure their PCs.

Hi Antti !

Thank you very much for this very exhaustive list ! :-)

GeSWall and DefenseWall seems to be very similar considering their approach.

Could you say why you prefer DefenseWall over GeSWall ?

Thank you.

by ako on 13. May 2010 - 15:56  (49729)

Well, both give excellent protection. I started to use DW due to a free Give-away. (I had tried GesWall free earlier.) I noticed that the developer of DW is very active and gives great support. This means that he corrects bugs very quicly. So DW gives almost always 100% protection. GesWall gets new versions not so often, but in practice it is also almost unbreakable.

You should try both and decide which suits better to you. For average Joe DW might be a bit easier to understand and use.

Thank you Antti for your answer !

I have investigated a little bit more about GeSWall and I finally saw the table showing the differences between the free and the paid versions of it.

The free version seems to be too restrained compared to the paid version and it seems clear that DefenseWall is better.

hey! my html tags are not working!

by Anupam on 30. May 2010 - 18:15  (50632)

Yes, they will not work. We have had some trouble with spammers using code injection... to hide links in their comments. Therefore, for anonymous posters, we have disabled the html code.
