Best Computer Virus Protection
What is computer virus and how to best
protect your computer
Surfing the net can be fun and learning experience. Whether you go online to catch
up with what's happening, keep in touch with your friends, listen to music and watch videos, or do serious school
or professional research, the internet is an endless source of useful, fun and educational stuff. But you need to
be alert while online as there are dangers lurking online to catch the unwary - in the form of computer viruses
and spyware. Before
you go online, you need to protect your computer from online threats.
What are computer viruses?
Computer viruses are small programs or scripts that reproduce themselves and
infect computer files and disks. They are spread and transmitted whenever files, disks, or programs are exchanged,
either online or via disks.
For example, when you receive and open email attachments from unknown senders they
could contain a virus. It's a good policy and one could say an important cornerstone of best computer virus
protection, to never open an email attachment received from an unknown sender, no matter how important or
appealing it seems.
Even email attachments from known people, like your friends, professors,
colleagues, or even your boss, can contain a virus. The senders themselves may not even be aware that they're
sending you a virus. Some computer viruses will duplicate themselves and attempt to email their copies to your mail
list, via Outlook Express for example. Norton Antivirus program is possibly the best to
use to prevent this from happening - the program will scan every email you send via Outlook Express and stop those
that might contain a virus.

virus protection system is foolproof
When talking about computer virus protection, anti-virus software, and firewalls,
it is important to stress that no virus protection system is foolproof. Even top security computer systems have
been infiltrated time and again by hackers and computer criminals simply by programming a virus. Files have been
deleted, accounts and identities have been stolen, and confidential files have been accessed by these hackers. This
is not to say that anti-virus softwares are useless, but to point out that these programs work and perform better
with the users' assistance.
Computer virus protection, anti-virus software, and firewalls are developed to
help you identify the viruses, the infected part of your system, and the process by which the virus can be
contained. But as pointed out before, they need your assistance. This is
best achieved by using a number of good virus-fighting and prevention software, rather than relying on any one
single anti-virus program to do the job.
New programs are developed regularly, and aside from these, there are also new
technologies put in use. With the improvements in technology, it is naive and erroneous to assume that viruses
remain as they are. They are constantly changing, becoming more sophisticated and harder to detect. Most advanced
computer viruses aren't detected until
they have brought down and controlled entire systems.
For best computer virus protection you need to install and use several different
virus and spyware prevention and fighting programs. Each one of those programs will deal with a different aspect of
your computer security and protection. Generally avoid installing and using two antivirus programs at the same
time, as they will conflict with each other. So, stick with one antivirus program only; paid one if you run a
business, or a free one for home computers.
In addition to a good antivirus program set yourself with a reliable anti-spyware
program, such as Malwarebytes, which is available in both
free and paid version. Naturally enough, paid version will do more, while free version only provides some very
basic protection. You should also ensure to have firewall installed and regularly updated, even if it's only
Microsoft's own firewall that comes free with Windows. There's also Zone Alarm program, also available as free and
Paid anti-virus programs work best
So, the first trick of good virus
protection is to subscribe to a reputable anti-virus software. Free software can detect and quarantine simple worms
and viruses, but they would be hard-pressed to detect the more sophisticated kinds. Subscription requires minimal
fees compared to the degree of protection your computer system receives. This is especially advisable to companies
and large businesses where several computers are joined in a network - using paid anti-virus program should be
mandatory. Computers for home use and ones that aren't used for storing sensitive data can do just fine with
free downloadable software.
Subscription automatically causes your computer virus protection, anti-virus
software, and firewall security to update whenever it is possible. This is an advantage because you can keep up
with the rapid sophistication of new viruses. The more updated your software is, the more efficient it is in
catching the virus.
Free antivirus software must also be updated or replaced with new versions
regularly. It is best to update your software whenever your software site alerts you of newer versions. But be on
guard against viruses which sometime can emulate (pretend to be) your antivirus program, asking you to click and
renew it. Always set up your free antivirus program to be renewed automatically, to avoid being tricked into
downloading a virus via a "pretend" virus program.
Scan your computer regularly
Aside from these tricks, doing virus scans on files, disks, software disks,
programs, and other applications must be second nature to you before opening them or downloading. A computer
virus can only install itself on your system by being downloaded as part of some other program, or inadvertedly
opened (thus downloaded) via an email attachment. So, think before you click.
Another good policy of computer protection against viruses is to keep back-up
files of the data and files in your computer in case a virus caused them to be deleted. Develop a good habit of
backing up your most important files regularly, so if you end up with a virus on your computer, the damage will be
Regular rebooting and "clean up" of your system also minimize susceptibility to
viruses. CCleaner is one of the best cleaning programs, while
File Shredder will systematically delete any sensitive files
and data that you no longer want on your computer. This is especially important for your computer security
protection, to avoid any potential identity theft.
Furthermore, use MS Disk
Defragmenter or free Defraggler to defragment
your files and avoid disk errors. A well optimized computer system will more efficiently fight online threats and
viruses, than the system that's slow and riddled with disk or file errors.
In conclusion, your best computer virus protection is achieved with the help from
a good antivirus and anti-spyware programs, and reliable firewall. Doing a regular clean-up of your system and
backing up your files will better optimize your computer, making it more resistant to potential online
