You don't drive a car without insurance...
by the same means you shouldn't *drive* a pc without A/V
It really pees me off when pple say.. *oh I don't have
anything worth stealing on my pc* or *I'm careful about what I download/open*.
Okies tell that again to the lady who was in tears in
front of me a few months ago, when told that a virus had infected
her bios and as such rendered her mobo totally useless. I saw 3 instances
of the same virus (CIH variant) in just 2 weeks each time totally
writing off the 2 pcs and 1 laptop.
Yes you may be careful what you open or download, but
there are plenty of virii (in particular the worms) that don't actually
require you to open anything, but will do some automatically within
Some worms such as klez aren't particularly damaging
to the pc.. but more of an annoyance and have a longer term payload.
- These worms can execute themselves
- They come with their own smtp engines
and can replicate themselves to anyone whose details are stored
on your pc.
- They will visit certain sites and sign
up your e-mail account to lots of nice spam sites.
- They can disable existing AV products
if your AV patterns aren't up to date and refuse to let any new
AV software be installed on your pc.
- Send themselves out to your friends under
a spoofed e-mail address.
Whilst doing my degree, I got sidetracked + undertook
research into virii and how they worked, and although I aint no expert,
I know enough to understand that even simple virii can have disastrous
People will pay circa £1000 for a pc but
moan at spending say £20 to protect it.
There are a few freebies out there so there is no excuse for anyone
not to use them -
AVG and Housecall to name a couple.
A common misconception is that firewalls can stop you
from getting a virus
-FALSE- A firewall protects your pc from external attacks and could
pull up trojans, but will be totally ineffective against stmp virii.
To those that say ooh I've never had a virus blah blah
blah, just look at the no of pple that do run A/V who say they've
pulled up viruses.. If you don't run the software..you wont know until
your pc starts behaving weird d'oh!
Unfortunately new viruses are being released every day
and we have to trust institutions like symantec and co to keep our
data safe.. but nothing is fool proof.
Its best to run A/V to protect against viruses
Firewalls against unauthorised attacks on, and attempts to access
Regularly check your operating system for critical updates.
oh and anti-spyware wont go amiss either
