The Best Free Spyware, Virus, and Browser Protection

Searching out, downloading, and installing free security programs from the Internet may appear to be a “no brainer”, given the vast quantity of such programs out there in the wild blue of the Internet.

The problem, as I see it, for the casual computer user, is not the availability of these programs, but which ones work; which ones have a deserved reputation for quality and functionality.

I’ve been involved in system and Internet security for many years (too many, it sometimes seems), and I have tested the following recommended applications and their updates over those years for reliability, functionality, and quality. These programs have a strong and loyal following that is well deserved.

Anti-virus software:

avast! 4 Home Edition

This anti virus app is a real fighter, scanning files on demand and on access, including email attachments. Let’s you know when it detects mal-ware through its shield function. An important feature is a boot-time scan option which removes mal-ware that can’t be remove any other way.

AVG Anti-Virus Free Edition 8.0.1

AVG Anti-Virus Free 8.0 now incorporates protection against spyware through a new combined anti-virus and anti-spyware engine as well as a “safe-searching component” which has been incorporated into the new AVG Internet Security Toolbar. This program scans files on access, on demand, and on schedule and scans email incoming and outgoing. For those on Vista, you’re in luck, it’s Vista-ready.

Avira AntiVir PersonalEdition Classic

This anti-virus program offers comprehensive protection with an easy to use interface. In the eight months I have been testing Avira I have been impressed with its performance, and I have come to rely on it as my primary anti-virus program. I highly recommend this one.

Anti Spyware Software:

Spyware Doctor Starter Edition

Spyware Doctor Starter Edition from PC Tools is an excellent choice, as a secondary line of defense. This free version of the award winning program, with its easy to use interface, is used by millions of people worldwide to protect their computers; it’s reported there are a million+ additional downloads every week. Be aware however, there is no real-time protection offered with this version and this is the reason I recommend this application as a secondary scanner only.

Spyware Terminator

Having tested virtually all of the major anti-spyware applications over the past year or more, I’ve settled, for now, on Spyware Terminator primarily due to its strong real-time protection against spyware, adware, Trojans, key-loggers, home page hijackers and other malware threats. Spyware Terminator excels in strong active protection against know and unknown threats. If anything, I find it perhaps a little overly aggressive. On the other hand, better this than the alternative.

Internet Browser Protection:


SpywareBlaster prevents ActiveX-based spyware, adware, dialers, and browser hijackers from installing on your system by disabling the CLSIDs (a system used by software applications to identify a file or other item), of spyware ActiveX controls. A secondary but equally important function offered by SpywareBlaster, is its ability to block spyware/tracking cookies and restrict the actions of spyware/adware/tracking sites in Internet Explorer, Mozilla FireFox, Netscape, Seamonkey, Flock and other browsers.

Since SpywareBlaster doesn’t scan for or clean spyware, but as stated earlier, prevents installation only, you should use it in combination with Spybot Search & Destroy and/or Ad-Aware, in addition to your normal anti-malware security applications to gain the maximum amount of protection.

Web of Trust (WOT)

WOT is a free Internet Browser add-on (my personal favorite), that has established an impressive 4.5/5.0 star user rating on CNET. WOT tests web sites you are visiting for spyware, spam, viruses, browser exploits, unreliable online shops, phishing, and online scams, helping you avoid unsafe web sites.

Adware Protection Software:

Ad-Aware 2008

In my view, Ad-Aware 2008 Free is the best free adware remover available. It does a good job of protecting against known data-mining, Trojans, dialers, malware, browser hijackers and tracking components. The only downside with the free version; real-time protection is not included.


Comodo Firewall Pro

The definitive free firewall, Comodo Firewall protects your system by defeating hackers and restricting unauthorized programs from accessing the Internet. I have been using this application for 10 months and I continue to feel very secure. It resists being forcibly terminated and it works as well, or better, than any firewall I’ve paid for. This is one I highly recommend. Amazing that it’s free!


The free version of ZoneAlarm lacks the features of ZoneAlarm Pro’s firewall. Its program control asks you regularly whether to allow programs; for some this can be intrusive and annoying. But it’s been around forever it seems, and it can’t be shut down, or out, by mal-ware.

Additional System Protection:


Do you want to get a better understanding of what programs are being added to your computer? Then WinPatrol is the program for you. With WinPatrol, in your system tray, you can monitor system areas that are often changed by malicious programs. You can monitor your startup programs and services, cookies and current tasks. Should you need to, WinPatrol allows you to terminate processes and enable, or disable, startup programs. There are additional features that make WinPatrol a very powerful addition to your security applications.


If you are an experienced/advanced computer user and you’re looking for a program to strengthen your anti-malware resources, then HiJackFree is one that’s worth taking a look at. This free application, from EMSI Software, offers a potent layer of additional protection to add to your major anti-malware programs. The program operates as a detailed system analysis tool that can help you in the detection and removal of Hijackers, Spyware, Adware, Trojans, Worms, and other malware. It doesn’t offer live protection but instead, it examines your system, determines if it’s been infected, and then allows you to eradicate the malware.


HijackThis is a free utility by Trend Micro which heuristically scans your computer to find settings that may have been changed by homepage hijackers, spyware, other malware, or even unwanted programs.

This application has a well deserved reputation for being aggressive in tracking down unauthorized changes that have been made to your system/applications.

The program doesn’t target specific programs, but instead it analyses registry and file settings, and then targets the methods used by cyber-crooks. After you scan your computer, HijackThis creates a report, or log file, with the results of the scan.

Because of the heuristic methods (behavior analysis), used by HijackThis, the results of the scan can be confusing/intimidating to those who are not advanced users. On the other hand, the strength of this program lies in the large community of users who participate in online forums, where experts (voluntarily and for free), will interpret HijackThis scan results for you, and then provide you with the information you need to clean any infection.

Despite the fact that you may only need this small application infrequently, it deserves a place in your anti-malware toolbox.

ThreatFire 3

ThreatFire 3 blocks mal-ware, including zero-day threats, by analyzing program behavior and it does a stellar job. Again, this is one of the security applications that forms part of my front line defenses. I have found it to have high success rate at blocking mal-ware based on analysis of behavior. Highly recommend this one!

SnoopFree Privacy Shield

SnoopFree Privacy Shield is a powerful application that guards your keyboard, screen and open windows from all spy software. I have been using this application for quite some time, and I have been amazed at the number of programs that have requested access to my keyboard and screen. In particular, programs that I am in the process of installing. If you’re serious about privacy, this is a must have addition to your security toolbox.


Surfing the Internet without using Sandboxie is, to me, like jumping out of an airplane without a parachute. Deadly! This application creates a “Sandboxed” protected environment on your machine within which you browse the net. Data that is written to your hard drive is simply eliminated, (or not, your choice), when the sandbox is closed.

Utilizing this application allows you to surf the web without the risk of infecting your system with mal-ware or other nasties. This is another security application I have been using for over a year and it has yet to let me down.

KeyScrambler Personal

KeyScrambler Personal is a free plug-in for FireFox, Internet Explorer, and Flock web browsers which protects all input you type into the browser from Keyloggers. This free version of KeyScrambler encrypts your keystrokes at the kernel driver level.

By encrypting your keystrokes at the keyboard driver level, deep within the operating system, a Keylogger is beaten since it can only record the encrypted keys which are indecipherable.

Unlike AntiVirus and AntiSpyware programs that depend on recognition to remove Keyloggers that they know about, KeyScrambler will protect you from both known and unknown Keyloggers.

Good luck and safe surfing.
