Many thanks to Steve Dickens of Liberty Computers Pattaya Ltd., for
this March 2007 update of the best computer Freeware available:
1
Best Free Web Browser
Internet
Explorer 7 (IE7) is a competent browser with enough features to meet
the needs of most users but does have on-going security concerns.
In the past IE has been a focus for security attacks and there is
little to suggest this has changed in IE7. Additionally, Microsoft
has a poor track record for speedily fixing IE defects and this has
left users open to drive-by attacks and other forms of zero-day
exploits.
There are several excellent
alternatives with the new Mozilla Firefox V2 [1] a solid first
choice. It's safer than IE, so safe in fact that many users have
reported no spyware infections since they started using the product.
It's also browses a tad faster than IE, is very stable and is more
standards compliant. The program loads slower than IE but once
running, it positively zips along. With tabbed browsing and over
1000 free extensions (add-ons) that allow you to customize
your experience, it provides most users with a major surfing
upgrade. Firefox is now my everyday browser though I still leave IE
on my PC for the occasional web site that's designed around IE's
non-standard features site: http://www.mozilla.org/products/firefox/
(5.6MB)
An equal first choice is Opera
It's a speed demon; probably the fastest of all the common browsers.
But it's much more than that; it's full featured, standards
compliant and safe. Just as Firefox is extensible through add-ins,
Opera can be enhanced using Widgets, though there are not nearly as
many of these available as Firefox extensions. Then again, it
doesn't need as many extensions as a lot of the features added by
Firefox add-ins are already available built into the standard Opera
browser. There's just so much to like about Opera V9 that you could
easily create a case that it's better than Firefox. Indeed, if I
could get an Opera replacement for some of my key Firefox add-ins,
I'd probably switch. Site:

Best Free Anti-Virus
Software
There are two equal recommendations in this category. First there is
AVG Antivirus 7 Free Edition. This product http://free.grisoft.com/freeweb.php/doc/2/)
has been continuously refined since it was first released in 1991
and the recently released V7.5 makes further improvements to an
already solid product. Additionally, it's relatively small, light on
resources, has regular automatic updates and handles email scanning.
There is a free and a pro version, the only difference being that
the free version has a few non-critical features disabled and has no
direct technical support.
Equally effective is the free Avast! scanner (http://www.avast.com/eng/avast_4_home.html)
though its funky media player style interface is not to everyone's
taste. Avast! also required periodic re-registration while AVG does
not. However Avast! does not seem to suffer the signature file
update problems that plague some AVG users.
Both
AVG and Avast! are excellent free products that will meet the needs
of most users. However neither can be considered to be the best
available. That title belongs to commercial products like NOD32,
F-Secure, the full version of Kaspersky AV and others. They are
however capable packages and offers the financially challenged a
real alternative to the major anti-virus suites.
However if you use these free products in conjunction with a free
on-demand scanner, you can achieve a level of detection approaching
that of the best commercial products. Further improvement is
possible by creating a layered defense using additional free
security products such as AVG Anti-Spyware (formerly Ewido).
On-demand scans should be run regularly, at least weekly, to check
for viruses and other malware that may have been missed by your main
scanner.

Best Free Adware/Spyware/Scumware Remover
A
couple of years ago most folks including myself relied on SpyBot
Search and Destroy and Ad-Aware for spyware protection. Alas spyware
has evolved so quickly that these once outstanding products are no
longer up to the task of providing primary protection though they
remain useful as secondary, on-demand scanners.
The
new generation of malware requires a new generation of defensive
products. Such products need to provide stronger active protection
and broader spectrum detection. The best anti-spyware programs,
Webfoot SpySweeper and Spyware Doctor are both commercial products
but there are two capable free products that I can recommend.
The
first is Microsoft's Windows Defender program
(http://www.microsoft.com/downloads/details.aspx?FamilyID=435bfce7-da2b-4a6a-afa4-f7f14e605a0d)
which is currently available as a free beta. Defender is the latest
re-incarnation of the excellent Giant Antispyware product that
Microsoft purchased late in 2004. Based on tests, Windows Defender
is not as effective as its immediate predecessor but still has solid
protective capability. Tested on several drive-by download sites
and its multiple real time monitors provided reasonable (though by
no means watertight) defense. It appears to be a little vulnerable
to polymorphic malware in particular and for this reason I suggest
it should be used in combination with regular on-demand scans from
the free AVG Anti-Spyware. My other reservation about Windows
Defender is that it consumes quite a lot of your processing power.
If you have a modern PC this should not be a problem but older
machines will definitely suffer a performance hit.
Note
that you need a legal version of Windows XP SP2 to run this program.
I've been told cracked versions of Defender that will run on any XP
SP2 PC are currently circulating on the P2P networks but I'd
approach those with caution. The idea of a cracked security program
strikes me as an oxymoron.
My
second choice is Spyware Terminator.
(http://www.spywareterminator.com) Unlike Windows Defender it works
with all versions of Windows so it's the stand-out choice for
Windows 9x users. It's no slouch either. Like Windows Defender it
has strong active protection. Indeed with its built in HIPS system
that warns you of any unrecognized intruders, it has stronger
protection against unknown threats than the Microsoft product. This
was confirmed on some tests I ran on drive-by download sites where
Spyware Terminator proved to be impregnable.
Spyware Terminator has it's own spyware detection engine but gives
you the option of using a second engine based on the Open Source
ClamWin anti-virus program. ClamAV is not the most effective AV
scanner on the market but it's certainly competent and the
additional protection can only be a plus.
On the
downside Spyware Terminator is slow to scan and can slow down your
PC a tad though not as much as Windows Defender. I've also heard
reports that support via the free forum is poor.
Choosing between Windows Defender and Spyware Terminator is not
easy. As of today I thing Spyware Terminator has the edge but it's
difficult to see how free product like this can remain viable,
particularly in a high support product class such as anti-spyware.

Best Free
Browser Protection Utility
There's a scumware plague at the moment. All it takes is a visit to
a pushy web site or a "loaded" shareware install and next minute
your Internet Explorer homepage has been changed, your default
search setting altered, unwanted ads pop up on your screen and
worse.
If you
use Windows 2000 or later my top recommendation for safe browsing is
a free program called Sandboxie (http://www.sandboxie.com) that
creates a special contained "sandbox" environment on your PC. While
browsing within the virtual sandbox provided by Sandboxie you are
totally corralled off from other parts of your PC. So any files you
download are isolated to the sandbox. Similarly, any programs that
are executed only do so within the sandbox and have no access to
your normal files, the Windows operating system or any other part of
your PC.
Usage
is remarkably simple. To start a sandboxed browsing session you just
click the Sandboxie icon from the Quick Launch tray and this will
launch your default browser in the sandbox. You can then use it in
the normal way to browse to sites or download files.
If you downloaded a file it will install normally but again will be
corralled off from your real PC. Anything it writes to your hard
drive, any changes to the Windows Registry or changes to the Windows
startup will be held in a separate area within the sandbox.
Similarly, any new processes running in your computer memory will be
sandboxed.
After you have finished browsing you can right click the Sandboxie
icon and delete all sandboxed files and processes and your PC will
be returned to the same state it was in before the browsing session.
If you want retain particular downloaded files you can save them
permanently before clearing the contents of the Sandbox.
The
advantage is clear: any spyware, trojans, keyloggers or other
malware products that infected your PC while browsing will be
eliminated.
Sandboxie works fine with all browsers but requires Windows 2000 and
later. It can cause problems on some PCs so backup before
installing.

Best Free Firewall
No other single product class seems
to cause as much angst to average users in their installation and
day-to-day use as Firewalls. For such users, Kerio Personal Firewall
is my top recommendation as it seems to cause the fewest problems
yet manages reasonable protection as well.
Kerio
dropped the product in late 2005 but thankfully Sunbelt Software,
the makers of the excellent CounterSpy anti-spyware scanner, picked
it up and will continue making it available under the name of
Sunbelt Kerio Personal Firewall (http://www.sunbelt-software.com/Kerio.cfm)
. Note that the free and paid versions of Sunbelt Kerio are the
same. If you don't buy the product some advanced features are
automatically turned off after 30 days. The product will also nag
you every time you start it. For some this is a small price to pay
for a great free firewall. For others it's a real turn-off.
If
performance rather than ease-of-use is your criterion then the
Comodo firewall (http://www.personalfirewall.comodo.com/) is the top
contender. The firewall itself is very robust and it comes with a
well designed intrusion detection system as well. Comodo also
supports internet connection sharing, while the free versions of
Kerio and ZoneAlarm do not. On the minus side the IDS is initially
rather talkative and this can unnecessarily alarm inexperienced
users. Additionally Comodo has been known to conflict with some
other security products though more recent versions seem to be
better in this respect. For the technically initiated this is an
outstanding free product and an easy first choice. Note that Comodo
requires Windows 2000 or XP SP2.
Next week we will look at the best free Trojan
scanners/removers, Rootkit scanners/removers, home use intrusion
detection, anonymous surfing software and applications suite. So
until then have a great week, any questions or general problems

In at number 6: Best
Free Trojan Scanner/Trojan Remover
My top recommendation here is AVG Anti-Spyware
[http://www.ewido.net/en/download/], a product formerly known as
Ewido until it was acquired recently by GriSoft.
Ewido started life as an anti-Trojan
scanner but has been repositioned as an anti-spyware scanner by the
new owners and the new name reflects that re-positioning. Whatever
ever it is called it is an excellent anti-trojans and a fine
anti-spyware program as well.
In tests Ewido/AVG Anti-Spyware
emerged as was one of the few products that could detect polymorphic
and process injecting trojans that were totally missed by many
anti-virus products. Unfortunately the free version of AVG
Anti-Spyware doesn’t have a memory monitor and this omission
significantly reduces the level of active protection provided.
However the on-demand scanner is excellent.
I recommend that all average PC
users who don't have an anti-trojan scanner download AVG
Anti-Spyware and scan their PCs weekly. I suspect you may be
surprised at what you will find. AVG Anti-Spyware is also pretty
good at removing some spyware infections so bear that in mind next
time you encounter a spyware product you can't remove with normal
anti-spyware products like Ad-Aware.
High risk PC users such as P2P file
sharers and frequenters of hack sites, should however consider the
industrial strength protection of Trojan Hunter or the full version
of AVG Anti-Spyware both of which offer the active protection they
need.
Note:
The free version of AVG Anti-Spyware is actually the same as the
paid version but after 30 days the active protection (i.e. memory
monitor) becomes non-functional, automatic updates are disabled and
kernel level self protection is turned off.

Best
Free Rootkit Scanner/Remover
Rootkits are a special kind of software tool used to hide trojans,
viruses and other malware from your anti-virus scanner and other
security products. Unfortunately, they are extremely effective which
means that some of you reading this will be infected even though you
believe your PC to be totally clean. Thankfully there is a new class
of security product now available called rootkit detectors that use
specialized techniques to detect these dangerous intruders.
Most
of these detectors require quite a bit of technical skill to
interpret the results but one of the simplest to use is also amongst
the most effective. It's called BlackLight
[http://www.f-secure.com/blacklight] and is currently available as a
free beta from F-Secure. The beta will expire on the 1st of April,
2007 but you can use it freely up to then. I suggest everyone
download this product and scan their PC. The chances of you being
infected are small but for five minutes work it's not worth taking
the risk.
BlackLight will detect most rootkits missed by AV scanners but is
can't provide perfect detection; no rootkit detector can. That's why
its' advisable to use more than one product.
If you
are an experienced user you should check out SysInternals
RootkitRevealer [
http://www.sysinternals.com/Utilities/RootkitRevealer.html]. It
uses a totally different different technique to BlackLight so by
using both products together you'll be getting excellent overall
detection. RootkitRevealer is however, harder to use than BlackLight
and is a bit prone to false positives so take care before deleting
detected items. If in doubt, consult the SysInternals
RootkitRevealer forum.
[http://www.sysinternals.com/Forum/default.asp]
Currently the biggest guns in the rootkit detection war are two free
Chinese products called IceSword
[http://majorgeeks.com/Icesword_d5199.html ] and DarkSpy
[6http://www.softpedia.com/get/Antivirus/DarkSpy-Anti-Rootkit.shtml.]
They are not really detectors like the other products rather they
offer a set of tools that can help reveal the presence of a rootkit.
These tools include a special process viewer, startup manager
and port enumerator that are not fooled by rootkits. It's left to
the user though, to interpret the results. In the hands of an
skilled user, these are amazing tools but not much use to
beginners.

Best Free Intrusion Prevention and Detection Utility for Home Use
These days all users face a real risk of malicious programs secretly
installing themselves on your computer. Anti-virus and anti-spyware
products dramatically reduce the chance of infection but are not
perfect. In particular they are prone to miss new malware products
not yet included in their signature databases. They can also fail to
detect malware programs that are cleverly disguised to avoid
detection.
To
prevent these malevolent programs from slipping by your AV and
anti-spyware programs you need additional defenses such as a Host
based Intrusion Prevention program (HIPS). These programs pick up
intruders by their behavior rather than by their characteristic
fingerprint. They are not limited to detecting specific malware
products but can target a wide range of interlopers. For the most
part HIPS programs all work in a similar manner; they stop any
suspicious behavior and then ask the user whether they want to allow
it. This, as we shall see, can be a mixed blessing.
Unfortunately most HIPS programs, including the popular free
programs WinPatrol and Prevx, generate a lot of warning messages
many of which are quite cryptic. These messages tend to alarm many
less experienced users who feel there is something wrong and simply
don't know how to respond. That's why these products are only
suitable for the very experienced (and very patient).
Thankfully a new generation of HIPS programs has emerged that use
white lists, black lists, policies and behavior analysis rules along
with other techniques to reduce the number of messages and the load
on the user.
A
prime example of this class of product is the free Cyberhawk program
from Novatix (http://www.novatix.com/cyberhawk/ ), and it only
occasionally issues warnings and even then the warnings are usually
real and need to be taken seriously. In essence it provides a vital
additional layer of protection to my AV and anti-spyware scanners at
little cost in terms of annoyance and no cost in terms of my
wallet. It is the stand-out free product in the HIPS category. Some
users have reported browsing performance problems after installing
Cyberhawk. But I have no evidence to substantiate this.

Best Free Anonymous Surfing Service
There are lots of reasons folks have for wanting to surf
anonymously, ranging from simple paranoia to possibly being murdered
by a malevolent foreign government. Whatever the reasons, commercial
services that offer anonymity are doing real well. However one of
the best services JAP [http://anon.inf.tu-dresden.de/index_en.html ],
is totally free. In fact JAP is perhaps a little too good. That's
why the German Police insisted in 2004 that a backdoor be put into
the product to allow interception of child pornographers. This was
done but subsequently removed as a result of court action by JAP.
Whatever, JAP offesr a level of secrecy that is better than many
commercial systems though not watertight. However expect your
surfing to slow down as you'll be relayed through a chain of servers
.

Best Free Software Suite
The Open CD site
[http://theopencd.org] offers for free a wonderful collection of
just about every application software product you need to run a PC
including the latest version of OpenOffice. Many of these freebies
substitute admirably for expensive commercial products. There is Abi
Word as an alternative for MS Word, OpenOffice for MS Office XP,
Thunderbird for Outlook, The Gimp for Adobe Photoshop, 7-zip for
WinZip and many more! Everything the average PC users needs,
genuinely for free!!!
