Antivirus Software Buyers Guide
As the internet continues to feature so prominently in our day
to day lives, antivirus software is more important than ever to
protect your computer from malicious intruders that are lurking all
over email and the net. Malware comes in the form of viruses,
Trojan horses, worms, spyware and phishing attacks and the
majority of antivirus software can detect and neutralise the
majority of threats. The methods different antivirus packages use
tend to fit into one of two camps and there are benefits and
drawbacks of each style of detection.
The first style is
a heuristic system that detects virus structures and activities. Its
advantages include the fact that it rarely needs to be update and
can respond to new and original attacks. The heuristic engines do,
however, have a habit of producing false positives, meaning files
are flagged that aren’t actually viruses.
The second
style will very rarely produce false positives as files are compared
to a database of known malicious files and software. This style,
however, needs regular updates to keep on top of the latest
viruses although this often automated. The best antivirus software
will use a combination of the two. Lately there has been the
emergence of online virus detection, which can be found in Panda’s
new Cloud Antivirus edition. The software takes advantage of
always on broadband, continually gathering the latest antivirus
information from a variety of users.
At the very least
your antivirus package should be able to detect and quarantine
malicious software although the majority will in fact eliminate
threats completely. When buying an antivirus package don’t just
consider the basic detection/neutralisation features but look for
parental control, firewalls, spyware removal and spam filtering.
Whilst these are all available separate from an antivirus package,
they’re handy extras to keep everything running smoothly and
safely!
Ease of use is also a very important factor in
deciding which antivirus package to buy. Microsoft Security
Essentials 1.0 is known for its simple user interface but look at AVG
9.0 and Avast for alternatives. This coincides somewhat with
performance. When you’re running a full scan, you shouldn’t be
able to tell. That is to say your computer should not begin running
slow. To be fair, any well known brand will offer this. The time it
actually takes for each piece of software will vary between around
half an hour to an hour with AVG 9.0 known for being fairly
rapid.
When actually buying antivirus software, be
careful you’re actually getting something for your money. The likes
of Avast are actually completely free and, even though more
comprehensive programmes are available, the majority of home
users will find free antivirus software sufficed. For home use, prices
are typically under £20. For small businesses, antivirus packages
that fit onto a router may be a suitable alternative in offices where
there are multiple computers. McAfee and Norton offer
comprehensive business antivirus solutions.
