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.

Is it good?

BTW, Eset SysInspector, Process Explorer, RunScanner, and SanityCheck supports 64-bit as well.

Could you please change the link for "Immunet" because the actual link leads to a "Page not found" notification with an automatic redirection to the new page.

The new address is : >

Interestingly, that "page not found", if you wait a few seconds, forwards automatically to the correct page.

MRG ? I would not recommend them to anyone, strage methodology, fake reviews,

by Anonymousio890 (not verified) on 27. July 2010 - 8:24  (54972)

You are 100% Right!

MRG is just a cover-up of (a Warez site).

Anyone, who knows enough the AV Testing sector, will not trust MRG!

Better stay with the AMTSO members:

by MidnightCowboy on 27. July 2010 - 8:56  (54974)

This is old news which was never real news at the time it was posted years ago. MRG is now a respected member of the software testing community although the relevance of what any of them do varies according to personal need.

Wilders is one of the most acknowledged forums in this area and this is an example of what their members are saying now:

"Their methodology is clear and in my eyes well chosen"

Sveta from MRG responds to questions at Wilders and also to myself whenever I ask. You can't get much more open and interactive than that.

You should never make software choices on the basis of one set of test results alone, but accumulate information from a variety of sources and then decide which best meets your own criteria. As for reliability, only select those whose websites are rated "green" by WOT. True this is not 100% infallible but is still the best guide as WOT ratings change very quickly if something dodgy is uncovered.

by ako on 27. July 2010 - 9:08  (54975)

No need to comment, MC explained it very clearly :-)

by MidnightCowboy on 26. July 2010 - 13:44  (54948)

Bit like PC Mag then :) So who would you recommend and why should these be any more relevant, or believable?

by Sputnik (not verified) on 25. July 2010 - 19:43  (54919)

There is "Secret disk" in the "Hiding files/folders" category.

I think it should go in the "Encrypting with virtual drives" category.

Hide in Picture (
Good Steganography tool.

by ako on 25. July 2010 - 17:22  (54914)


by Sputnik (not verified) on 24. July 2010 - 17:46  (54873)

Would you consider, ako, to add a new category : Steganography ?

I think it can be considered as security software in the sense that, a little bit as the "Hiding files/folders" category, it's purpose is to hide something inside something else so to protect it.

Thank you

by ako on 24. July 2010 - 17:55  (54874)

Good idea!

by Demon (not verified) on 24. July 2010 - 6:38  (54850)

i think you should add trinity rescue kit to your list

by ako on 24. July 2010 - 18:00  (54875)

It is there already :)

by Sputnik (not verified) on 24. July 2010 - 0:12  (54828)

There is one category actually missing in this very exhaustive list : softwares for hiding folders and files.

In this category I would suggest "Hide Folders" :


I am not saying it is the best, I just mention it as a reference.

This one can only hide folders, not files.
