Probably the Best Free Security List in the World

Probably the Best Free Security List in the World - Page Index
1. Introduction

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 The Best Free Security Software for PC. 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.

Just Interested in the Prevention Antivirus is it antivirus and antispyware? I noticed it uses Sophos and Lavasoft engines is that just for the paid version. Is that a good combo?

by ako on 26. January 2010 - 6:39  (42094)

Haven't tested, but it should be reasonable AV+AM+AS.

by ako on 26. January 2010 - 6:39  (42095)

I had the same experience with a friend's PC.

There is a new VirusTotal Uploader version available here:

For the My Documents taking a long time to load, I have a relative who had the same problem and it stumped several of us who are somewhat computer literate. We managed to find that she had a very large file that was taking forever to load. It was a Garmin map update file that was over 1 gig. Once that was deleted My Documents loaded just fine. Check to see if you have any very large files in that folder or any sub-folders in My Documents and either back them up and delete them or just delete them if you no longer need them. Hope this works. I run MSSE on Windows 7 and have had not problems with it.

Any comments on the hazard shield? I didn't get much info on the website other than its got a new version. Is it still in beta?

by ako on 5. February 2010 - 9:01  (42859)

Haven't tried that.

I just tried the free edition of Forticlient Security Suite, customized to Anti-Virus, Firewall, and Application detection modules. So far, so good, and does not seem to hog resources or present frequent annoying alerts.

Good alternative to more of the well-known security suites. Something to consider.

by ako on 12. February 2010 - 8:02  (43425)

Interesting. Thanks for informing!

This has to be the best list that I've ever come across,.. well done !
I've recently installed "Immunet" cloud based malware protection,.. so far, so good. I'd be interested to know if any of you have anything good or bad to say about this one.

by ako on 14. February 2010 - 12:37  (43597)

I've got the impression it gives a good extra layer.

by Anonymous on 19. February 2010 - 10:47  (43947)

Great list. I reference it all the time. Personally I think Prevx should be removed since the free version is virtually useless. "Pay now" and remove your malware.

by ako on 19. February 2010 - 11:02  (43948)

I disagree. To know that you are infected is even more important than being able to remove. (And you can do it then by hand or with other tools.)

by Anonymous on 24. February 2010 - 2:04  (44319)

There is also a free version of Outpost I don't see that linked in your list. Not the "Trial-Pay" one, just the free one on the same page.

Definitly the best best list. unfortunately I saw it after using the net for five years.

by ako on 26. February 2010 - 22:27  (44574)

Thanks! I have had it public only 4 years and 3 months so far (first only in finnish though).

The Clam Sentinel program provides a real-time antivirus scanner for the free ClamWin antivirus program. ClamWin is required to be installed and configured first, and then Clam Sentinel can be installed. Sentinel is designed especially for older computers, but it has been tested on Windows XP and Vista machines and is available for use on them as well. It will probably work on Windows 7 also but has not been extensively tested on it.

Sentinel installation and configuration is easy. Sentinel comes with a default configuration that is suitable for most users, but it can be "tweaked" via two configuration option menus (Settings/Advanced Settings) that are available by right clicking on the Sentinel badge icon in the Windows System tray. Sentinel provides real-time scanning (Via ClamWin) for hard drives, USB/removable drives, and the optional detection of Potentially Unwanted Programs. It has real-time and memory scan logs and provides easy access to the Quarantine folder.

Both Clam Sentinel and ClamWin are free, open source programs. ClamWin can be downloaded from

Thanks for that. Clam Sentinal does not have a home page as such, so this link will take you to a forum page with some info and a download link.

You should add "Simple Adblock" to the browser security list. It uses Adblock Plus' EasyList. Been using for it ~6 months on IE8 and haven't noticed an ad on 98% of sites.

True but it's not really freeware. It's crippled payware.

by ako on 9. March 2010 - 20:05  (45262)

True. For this reason there reads: Prevx (no removal, see footnote)

by Anonymous on 12. March 2010 - 23:12  (45459)

on My mind, it will be nice, if you mark separatly x64 bit application

by ako on 13. March 2010 - 1:02  (45464)

This is something I have been thinking of. However I would need help here, as it would be an enormous task to do this.

by J_L on 17. March 2010 - 16:46  (45720)

For "Better XP Mode" under "Windows 7 Security" please include VMware Player.
