BEST FREE ANTIVIRUS SOFTWARE FOR WINDOWS
Quite a large number of antivirus vendors make free antivirus software
available for home and SOHO users. But how do you choose the best free
antivirus? For starters, don't just consult some random Web list
advertising the best free antivirus. You need to make sure the free
antivirus has been properly tested and is ranked according to its
detection and protection capabilities. Remember, the best free antivirus
is really only the best if it keeps your computer safe from viruses,
spyware, and other malware. Here are the best free antivirus programs
for Windows - based on how well they detect and protect.
1. Avast! Free Antivirus
This is my new top pick for the best free antivirus software in light of
recent developments. Avast has steadily been improving its detection
rates over the past few years and now ranks with the some of the best.
Avast has the most features of all the free antivirus with full
real-time capabilities including web, e-mail, IM, P2P and network
shields, boot-time scanning, and a behavioural blocker. Version 6
brought even more features including an internet site ratings plugin,
script malware protection and a limited (non-configurable) sandboxing
feature. It's arguable whether their ratings plugin offers comparable
levels to WOT, but the script malware protection can prevent certain
browser exploits, a feature not available in any of the other free AV's.
Although the sandbox is a very useful semi-automated security feature,
the default settings involves a pop up to ask whether a software should
be sandboxed for not - for the typical average user this can be slightly
confusing though it can set to sandbox the software automatically.
Avast is also relatively light on resources. Note that Avast requires a
free registration to function after 30 days.
Avast! Free Antivirus earns its spot as one of the best free antivirus
because it not only offers standard scanning, it also provides scans on
bootup. This can greatly increase the chance of removing stubborn
infectors, particularly those that use resuscitators to thwart removal
attempts. Avast! Free Antivirus supports Windows 95/98/Me, 2000, XP,
Vista, 7 and 8.

2. Avira AntiVir Personal Edition
This is another high quality free antivirus, and formerly most peoples’s
top pick. The primary reason it lost it status involved the recent
controversy of AntiVir including a re-branded Ask toolbar in their
installer, and a temporary spate of advertisements promoting a possible
'scareware' company. In spite of the negative press though AntiVir is
still a top notch antivirus scanner with outstanding detection rates of
malware, higher than almost every other antivirus according to tests.
AntiVir is still a good choice for a free antivirus scanner,
particularly for high risk users.
However, there are some minor reservations. First, AntiVir does not
include web or e-mail scanning capabilities; this is only available in
the paid version. The lack of an e-mail scanner is not a disadvantage,
it just means that AntiVir won't warn you of infected emails before you
open them. But should you open an infected email, AntiVir will still
spring into action, so it doesn't mean that you're not protected from
email-based infections. Also, AntiVir contains a rather intrusive
advertisement every time it updates. Although AntiVir had signature
updating problems in the past, this issue seems to be fixed now. Avira
AntiVir routinely nabs some of the highest scores from AV-Test.org and
other antivirus testing agencies.

3. Microsoft Security Essentials
Microsoft Security Essentials is a favourite of mine with great
detection rates, particularly for rootkits. Even more impressive is the
fact that Microsoft Security Essentials has very few false positives, is
light on resources and is good at removal of existing malware. MSE is a
great choice for average users because of the minimal user interaction
required. It automatically updates and removes threats. No registration
is needed, apart from a quick validating of Windows, and there are no
nag screens or advertisements.
The main downsides are the slow scan speeds and the lengthy amount of
time it takes to quarantine malware, though in my opinion these are
rather trivial concerns, as for example a scan just be run overnight.
MSE also is not available in certain countries so users there will have
to look elsewhere. Note that Microsoft Security Essentials requires a
genuine copy of Windows to install.
Microsoft Security Essentials earns its spot as one of the best free
antivirus as it has consistently performed admirably on third-party
antivirus certifications and detection tests. Microsoft Security
Essentials is not only free for home use, it's free for small businesses
with up to 10 computers to protect. Microsoft Security Essentials runs
on XP, Vista, and Windows 7 and 8 but can only be installed on genuine
Windows installations (i.e. those that are properly licensed).

4. Panda Cloud Antivirus
Panda Cloud Antivirus is not only one of the best free antivirus
programs, it’s also the only free cloud-based scanner, Panda antivirus
software takes all the processing off your PC, giving you a lighter,
faster, and more proactive antivirus protection. Or for a very low price
you can upgrade to Panda Cloud Antivirus Pro and gain additional
features as well as 24/7 tech support.
Panda Cloud Antivirus is an excellent choice for average users with a
simple interface and completely automated features with automatic
updating and removal of malware. The detection level is generally very
high, but according to the latest test data, detection of zero day
threats is slightly lower. PCA uses 'cloud' technology to provide for a
much quicker release of updates as all definitions are stored in the
cloud and thus the moment Panda updates their blacklist all users of PCA
with an internet connection are protected from it.
Panda Cloud Antivirus has a behavioural blocker and web protection,
which will certainly increase your security. However as you can simply
use one of the other free AV's with a separate behavioural blocker (for
further details see our Security Wizard) to achieve possibly even better
protection, this is not necessarily an advantage.
One minor reservation with Panda Cloud Security is that it seems to
erroneously detect certain browser/system-related applications, for
example VideoCacheView, and because of the automatic quarantine this
made it a fraction bothersome.

5. AVG Free Edition for Windows
AVG Free Edition is a classic, one of the longest running free antivirus
packages available for Windows 8/7/XP/2000/NT/ME/98. Installing only
30Mb of files and 4 running processes, AVG Free Edition is the smallest
antivirus scanner we've tested and may well be the best free antivirus
choice for an older PC that has limited system resources.
Although AVG Anti-Virus Free Edition is also a decent choice for a free
antivirus this venerable antivirus has had some shaky results in
detection in the recent past, however it now offers a high level of
protection. This is probably due to the inclusion of a fully-fledged
behavioural blocker that is the "Identity Protection" protection. This
provides a very important additional layer of protection, on the other
hand though a similar protection level can be achieved by using one of
the free antivirus above alongside a separate behavioural blocker.
Unfortunately AVG free has grown considerably in size, has very slow
scan speeds and also advertisements (but they can be disabled)

Comodo Internet Security is the free, multi-layered security application
that keeps hackers out and personal information in. Built from the
ground upwards with your security in mind, Internet Security offers 360°
protection by combining powerful Antivirus protection, an enterprise
