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.

Hi! I just wanted to inform that I can't download the YASC application called secure-it. I've tried different places, but they all take me to a webpage called XXXXXXX, but the download doesn't start, or is nowhere to be found. I was able to download harden-it by YASC also, but I downloaded it from Major Geeks. Sadly, Secure-it isn't available on Major Geeks. Can you give a link where I can download it? Harden it is only for WinXP and earlier, when I try to install it on Vista, it tells me to download Secure-it, but I haven't been able to. Thanks a lot, and congratulations on a great and useful website!

PC Tools Free Antivirus

It is there (Spyware doctor with antivirus)

by MidnightCowboy on 7. September 2010 - 8:04  (57395)

This is the Google pack restricted/limited (IMO very!) version of Spyware Doctor +AV

as opposed to PC Tools Free AV

Hey Ako, in the section removing stubborn malware can you elaborate a bit more on it. I am mostly wondering about how you run DrWeb Cureit and Emsisoft Emergency on UBCD4Win. Are they already on the UBCD4win or do you have a USB plugged in with these programs on it (would the programs then have to be portable versions?). Also do you run full scans for all the suggested scanners or some quick scans and some full?

Many thanks for the great freeware list!

by ako on 4. September 2010 - 8:20  (57247)

Yes, you should copy them to the hard disk or USB stick. Run always "full scan".

How is this related to security? Is this alternate DNS? Where are the IP addressess for their DNS servers?

by AlanMcAlan on 3. September 2010 - 17:31  (57214)

You can (through quite a painstaking process) register, create a domain, and use their DNS servers with your own custom filters, almost like OpenDNS.

by Adrastos (not verified) on 5. September 2010 - 17:10  (57313)

its not recommended for the faint heart I'd still take openDNS over that...

Hey Ako, this is becoming a monster! Looking great! I am really liking the new area you added about removing stubborn malware.

by ako on 20. August 2010 - 20:36  (56437)

I'd be happy if people will find it useful.
P.S. Thanks for encouragement! :)

Thank you Ako for adding my website: to your list. I greatly appreciate it!

You are welcome :)

In the anonymous browsing tools you refer Ultrasurf

In (Practical Internet Privacy) you can read: "Well, you would normally avoid government-funded freebies that log everything. One such service is Ultrasurf – linked to the Falun Gong run GIF Inc, and headed by an NSA scientist to break Chinese censorship."

by ako on 14. August 2010 - 23:23  (56037)

The overall opinion of that page seems OK.

Vba32 did great, while Sophos was satisfactory.
