DECEMBER, 2013 - COMPUTER SECURITY WITH ANTIVIRUS AND FIREWALL SOFTWARE
New PCs almost invariably
come with a free trial version of a subscription security suite from a company
such as Symantec or McAfee. But you can probably skip paying for those programs
and still be safe online, our latest tests confirm. The types of security available include:
·
Free security suites
These offer
not only malware protection but add a firewall and in some cases, other extras
such as a child filter. But none of the free suites we tested include some
other features that are often found on pay suites such as anti-spam protection,
built-in backup software, and a browser toolbar that will alert you when you're
visiting sites that host malware.
·
Pay security suites
Such suites promise
comprehensive protection in one package. They offer not only malware protection
but also a firewall, an anti-spam filter, and other extras. The latter usually
include a child filter, often include a browser toolbar that will alert you
when you're visiting sites that host malware, and sometimes include a file shredder
and file backup software. You buy the program online, either by downloading it
or upgrading from a free trial version carried on your PC. You can use a suite
on as many as three computers in the same household. Prices typically range
from $40 to $80, and include a year of service. After that, you'll typically
pay another $40 to $80 per year to renew service.
·
Free anti-malware programs
These are
mostly downloads. But there's also the protection that Microsoft builds into
its operating system.
·
Spam filters
These offer
supplemental protection that you may want because your e-mail program isn't
adequately filtering out unwanted messages. Often built into pay suites.
·
Anti-phishing toolbars
Free
security toolbars available for all major browsers provide extra protection
against phishing sites, especially if you're using an older browser version or
just want extra protection. Widely used
browsers such as Chrome, Firefox, and Internet Explorer have built-in features:
o
Internet Explorer
8, 9, 10: SmartScreen Filter (on by
default)
o
Chrome: Phishing and Malware Protection (on by
default)
o
Firefox: Phishing and Malware Protection (on by
default)
Most free standalone
anti-malware programs focus only on keeping malware from installing or
downloading on your system. Some free security suites include a firewall and
child filters. For the features listed below, you'll most likely need a pay
security suite.
·
IM protection
This feature
blocks attempts to deliver malware via instant messages.
·
Firewall
A firewall
keeps malware from downloading and prevents a malicious Web site from grabbing
data off your computer. The best firewalls protect you from incoming and
outgoing threats, and pop up clearly worded alerts when a potential breach is
detected, to help you decide if it's OK to let the data go through.
·
Anti-spam
The filters
provided by many e-mail programs or ISPs might be all you need to block
unwelcome mail. The anti-spam feature on suites (and standalone, and often
free, programs) offer supplementary assistance if too many junk e-mail messages
are still getting through.
·
Child filter
These block
access to certain sites unsuitable for children.
·
Privacy filter
If you're
about to inadvertently divulge personal information, a privacy filter will
provide a warning.
·
Browser toolbar
These
toolbars can be placed into popular browsers to help prevent phishing.
·
File shredder
This feature
allows you to erase files to prevent their recovery from your hard drive.
·
File backup
A suite with
this feature will periodically back up your files to another drive.
Free is fine for most people
As long as you surf
safely--that is, you never download software from unfamiliar sites (those
downloads might carry malicious software) or click on e-mail links to access
bank or other personal accounts (those links are favorite tools for
cyberthieves)--the free anti-malware programs we recommend should adequately
protect you.
Make sure Windows firewall is
on to help block malware and keep malicious web sites from grabbing data off
your computer.
Consider your computer
Some suites demand more
resources than others. Machines with less than a gigabyte of memory might run
too slowly with such gluttons. Similarly, some programs' scans take longer than
others. This is important if you have an older computer
Choose a pay suite mostly for convenience and features
An advantage of a pay suite
is that it simplifies your security regimen. It requires just one download and
installation and a single upgrade to its database when necessary. Its single
interface can also be easier to use than multiple stand-alone programs. The extras you get with a suite include a
built-in firewall, which can block attempts by malicious software to access
data on your computer. In our tests, the firewalls in the best suites afforded
slightly better protection than those built into Windows operating
systems--though the latter offered adequate protection for most.
With free products, help is
usually limited to online FAQs, forums, and tutorials. Most of the tested pay
suites offer free e-mail and chat support. Most also offer phone support, though
some charge for it.
