WAYS COMPUTER VIRUSES ARE SPREAD
There are different ways in which a virus can spread from computer to
computer, but let's take a look at the most frequent ways in which
people run into viruses, spy ware and Trojans via the Internet.
Adult Websites: adult websites, gambling websites
and other less than trustworthy websites will attempt to automatically
access your computer when you visit them. They often install adware bugs
that will cause a flurry of pop ups to appear on your screen. This
adware will often allow for other programs with even more nefarious
purposes to be installed and before you know it, your computer will be
swamped. To stop these rogue websites, adjust the settings on your
antivirus software and firewall so that no outside connections can be
made and no programs can be installed without your express permission.
Email attachments:It has been discovered that since
the advent of email attachment by Microsoft's Outlook Express.it is been
used as medium by which viruses can be transferred from user to user.
It is advised that if you don't know what an attachment is, don't open
it. simply use common sense when opening attachments in your email.
Boot disk Infected :a virus can still be spread if an infected
disk is in your hard drive and you attempt to restart. When you start
your computer, your machine will always check your drives to see if a
disk with boot information is present. If one is, your computer will
likely automatically attempt to boot from the disk and not from your
drive. If a virus is present in the boot disk, it will often be
activated and you will become infected. Always know the origin of any
disk you put into your drive.
Local Area Networks. If your computer is connected
to a home network or if your work computer is part of a larger network,
you may find yourself with an infection through no fault of your own.
Someone else on the network downloaded a bug by accident, and within
minutes, the entire network could be infected. There isn't much you can
do to stop these kinds of infections, short of having your network
administrator ensure that everyone's antivirus software is up to date so
that the invading bug can be removed as quickly as possible.
Softwares. Downloading files or softwares from the
internet can create an access to virus infection on you pc. The key here
is to only download freeware or shareware from a trusted source like
CNet that always ensures your safety.
Phishing : A phishing scheme starts when you receive an email from a
website claiming to be your bank or credit card company, people end up
with their identity stolen and a computer fill of viruses. Often times,
when you visit these sites, spyware, adware and viruses are
automatically installed on your computer The smartest thing you can do
is to simply call your bank or credit card company if you receive an
email saying there is a problem with your account instead of blindly
following links in your email.
Chatting Messagers: These programs are often targets of hackers
who see an easy way to trick people into clicking links that lead them
to rogue websites. Common sense can keep you out of trouble, however.
Only chat with people you know and never follow links to sites that you
don't recognize. You should easily be able to keep Internet worms,
viruses and other bugs at bay
Hackers. Today, people understand the value of good online protection,
but hackers can still pose a problem if you allow your protection
software to lapse. The best way to beat hackers is to ensure that you
have a firewall and up to date antivirus software.
External Mobile Devices. There really is no way to
stop such an infection from happening, since we all buy peripherals that
work with our computer, but we can ensure that we have the tools ready
to go if an infection should happen. Keep your anti virus software up to
date at all times and you should be able to wrestle control back from
any Internet bug.
Fake Anti Virus Software. This is one of the most frustrating
ways to become infected with a virus or worm. There are dozens of anti
virus and anti spyware programs you can download for free on the
Internet and a surprising number of them actually do exactly the
opposite of what they claim. The product websites make outrageous claims
that their product can protect you from a whole range of threats, when,
in reality, their product will only make things a thousand times worse.
Only download antivirus programs from trusted sites or from websites
that you know are completely legit.
When we know how spread, we can put an end to their reign of terror
online. It is only with the right knowledge that Internet users
everywhere can beat online bugs for good.
