Computer Viruses, What are They and How you can Overcome them


  • pg 1
									Computer Viruses are the Definition of trouble

All over the world, computers and other devices
that are connected to the internet are at risk of
becoming infected by a computer virus. But what is
a computer virus, anyways? Like with humans, a
virus can make your computer "sick", and can be
spread from computer to computer. A computer
virus is described as a program that infiltrates your
computer's defenses, disrupting normal computer
functions, and can even delete programs, files, and
can even wipe your hard drive clean. Some viruses
simply make things frustrating, and are intended as pranks. Others, though, have a
more destructive purpose, and can make things very difficult, and can even wind
up costing you money for repairs.

Different Types of Viruses

Today, there are several different types of viruses. Most of them infect your
computer through attachments in emails, or by clicking on popup ads, or even
simply visiting a website. Some viruses are harmful, and others malicious, but not
a real threat, as stated previously. Sometimes, all that happens is that you get
spyware dumped in to your system. Every week, a new, stronger virus is being
created, making antivirus companies stay on their toes. But what are the different
types of viruses out there?

• Trojan   Viruses - This type of virus is probably the kind that is most often
encountered. They lie in wait on websites, popup ads, and emails, and don't make
themselves out to be threats. Some get caught right away by antivirus software, and
are easily taken care of. Others, though, can be a bit sneakier. Trojans can be
disguised to look like a legitimate file. But the second you open that file, you've
infected your computer. Some Trojans are destructive, and others dump spyware in
to your system.

• Worm Viruses - A worm is a very serious risk to your computer, and others.
Worms are defined as a sub-class of viruses, and can spread without any
interaction from users. When a worm infects your system, it uses file and
information transfers to carry itself in to your system. Email is the preferred choice
of travel, but really, you can pick them up just about anywhere, at any time, and
they don't always make themselves known to your antivirus. The most dangerous
part about a worm is that it can make replications of itself, and if it is in your
email, it will infect every single person you have listed as email contacts. They are
destructive, and can wipe out hard drives.
• Blended   Threats - These are probably the most sophisticated form of a virus
attack. Blended threats combine some of the worst attributes of malware, viruses,
worms, and Trojans in to a single, but very serious threat. They aren't encountered
very often, but when they are, watch out. They use vulnerabilities within your
system to infiltrate, infect, and spread. They are also capable of spreading to other
computers, like a worm does. But they don't attack just one part of your computer.
In fact, they are capable of launching multiple attacks to .exe files, HTML files,
and so on all at the same time.

Computer Virus Removal and Future Protection

Now, this should be obvious to most. The best
way to remove viruses and protect your
computer is by investing in antivirus software.
Sure, you can download some antivirus
programs for free, but they don't offer the full
protection plan like the programs you purchase.
Depending on what you do while on the
internet will determine what kind of antivirus
program you need. If you just play games, and
surf the web for leisure, then you don't need
anything overly fancy. But if you run your business on the web, like web designing
and other such occupations, then you might want to spend a little extra and get the
more advanced programs. Of course, these are just opinions and suggestions. In the
end, it's personal preference on what you get.
