Probably the Best Free Security List in the World - Part I


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.

Mitro was already in 14.11.

Thank you for the information :).

The link "Five (easy-to-follow) tips for strong passwords and secure accounts" is no longer valid.

Sorry, but I have to object to (seemingly) generally giving download links from or Maybe I misunderstand the text.

These are in my experience some of the worst sites adding unnecessary download programs and wrappers that in turn then get (ab)used to sneakily get PuPs installed.

Recommending Cnet/ IMHO equals aiding the proliferation of one of the nastiest kind of malware that currently is way too common. I have found that almost always there are other options.

Stupid captcha feature.

Nasties, that you can typically uncheck during installation, and if you accidentally install them, you can easily uninstall them. Or is there something more serious I am not aware of? (I yesterday reinstalled my Windows and used many times without nasty suprises.)

by eikelein on 10. January 2015 - 11:31  (120504)

Well, IMHO you only really know after you run ADWcleaner and Malwarebytes and both come up clean.

I encounter quite often the opinion that all PuPs can be removed in Programs and Features. Not true in my experience.

Babylon, Conduit and Searchscopes for example (there are many more) come up in these scans ONLY and can completely ruin the internet experience.

by ako on 10. January 2015 - 20:37  (120508)

Just to convince you: I scanned the PC today with Hitman Pro, MBAM and AdwCleaner. No problems found.
I am now scanning with Antivir. If it sees anything, I will report it. But I don't expect to see anything exiting.

by ako on 11. January 2015 - 14:24  (120520)

No problems here. But generally you are right. Most people probably just click, and there may be next time when I use these services more efficient efforts to put something on my system.
But the work for changing all links is huge. Perhaps we should add some warning first....

Thank you for your comments.
