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.

The security suite link for Forticlient leads to a mobile AV. It should go here:

Hey ako
have you heard about this one?

It's been used a lot in Avast forums too

by Anupam on 3. November 2010 - 17:45  (60725)

Thanks a lot for informing about OLT mrpink. It looks like quite a useful tool. I think you should mention it in the Software Suggestions on our forum too :).

by mrpink on 9. November 2010 - 17:25  (60933)


by Anupam on 9. November 2010 - 18:25  (60935)

Thanks a lot mrpink. I am sure others will find it useful.

by mrpink on 2. November 2010 - 21:15  (60678)

Actually, the guy has created other tools too

and a bootable cd called OTLPEStd.exe but i can't find it there

Looks good!

"VPN sofware:
Logmein Hamachi
Comodo EasyVPN
TigthVNC" Sofware should be spelled "software" and TigthVNC should be spelled TightVNC. SMAC is also a great MAC address spoofing program that you should add, it works even for Windows 7 64-bit

"Vista/Windows 7 spesific security" <-- typo still there

by Dwayne Ingram (not verified) on 26. October 2010 - 15:25  (60203)

Is it safe to download from test my pc?

by ako on 26. October 2010 - 16:43  (60210)

See discussion below: most likely yes, but we will not guarantee it. The Wot-rating is green.

by Vicky (not verified) on 25. October 2010 - 11:51  (60129)


Thanks for the comprehensive list, five stars!

I'd suggest you to add 360Amigo System Speedup. You can find information on their website

I have found this rather new tool the best in cleaning and optimization. It is more effective than other similar products, and you can really see the difference in PC usage after a clean.



by Anupam on 25. October 2010 - 11:53  (60130)

Thanks for the suggestion. 360amigo was recently featured on our site here :

Avast picked up a Trojan download attempt at while trying to download all tests

by Anupam on 25. October 2010 - 11:48  (60128)

Yes, many files in that zip file are detected as threats by Avast. But, it could be because the files are for testing purpose. Still, I would advise not to use those files unless you are sure of what you are doing, or you have confirmed from someone that the files are for testing only, and are not infected otherwise.

But, where did you find the site from? I think this site is not posted on this article, or is it? And if its not on this article, why post it here?

by ako on 25. October 2010 - 13:29  (60136)

It is there, Test My PC. Many AV:s flag testing software as threats. That's a kind of hoax from AV-companies. I'm pretty sure this is the case here.

by Anupam on 25. October 2010 - 13:38  (60138)

Thanks for explanation Ako. I was looking for testmypcsecurity, and I didnt find it. Didnt look for Test My PC :D.

Yes, I too thought that because of the nature of the test files, Avast was flagging it as threat.

by J_L on 24. October 2010 - 19:04  (60101)

Can you add What's New to the Index please? It would save me from a lot of scrolling.

by Anupam on 20. October 2010 - 17:23  (59799)

Link for Avira Rescue CD has changed. Its now available here :

by mrpink on 15. October 2010 - 18:27  (59598)
