One uses an antivirus for,
of course...., to protect itself from the viruses. These
charming small animals which one collects via the Web.
It is really necessary to be disturbed for surfer without

A virus is a small program located in the body of an other
program, a software, an e-mail.... who, when it is opened,
carries out the instructions that its author programmed.
For the majority they multiply but they all are not destroying.
A small anecdote: the first
virus was created by a student in data processing with
l’ The University of California (Fred Cohen) in
1983. Following an experiment on the safety of the systems,
the program called then Virus was launched on a UNIX system.
The purpose of it was to contaminate all the programs
of the PC, which functioned perfectly.
distinguishes thus various types of virus:
-) Worms: viruses able to be propagated through a network.
-) The Trojans (Trojan horses): viruses which make it
possible to create a fault in a system (to generally allow
its originator to be introduced into the system infected
in order to take control of it).
-) Logic bombs: viruses able to start following a particular
event (date system, distant activation,...).
Think of safeguarding your
files. A breakdown can occur very well at any time or
an enormous planting because of a virus. Use of the CD-R
..... If you have a site lodged by your FAI, think that
you can use the remainder of space allocated by your shelterer
to store your personal data: for example, if you have
a capacity of 100 Mo and that you used only 50 Mo for
your site, you can fill the remainder by personal files
very well to avoid engraving them. There are also sites
which enable you to store your files: Pensebete.com,
If you receive recurring
e-mails containing of the viruses, go on the webmail of
your FAI and put the shipper on a black list. It is simple,
it is enough most of the time to select the e-mail and
to click on "black list" then to empty the corbaille.
Thus your FAI will destroy the e-mail before sending it
to you. Often there is evil to identify the original address
of the e-mail. To know it made a right click on the e-mail
and Properties, thus you can see the address. You can
also find it in details.
In order to be propagated,
the viruses have recourse to the address book of Outlook.
An infected e-mail is sent to all your contacts without
you knowing it. There is on certain Outlook Express the
possibility of countering: select menu tools->Options->Security.
In antivirus the Protection zone it is necessary to notch
the two boxes entitled: To inform me when other applications
try to send messages of my share and not to authorize
the opening of the enclosures likely to contain a virus.
An easy way so that a contaminated e-mail is not read
in the shutter of visualization: because even if you do
not open it and that the message is posted in the window,
it is likely to be carried out, as for the spams. Go in
Posting-Provision and decontaminate the Afficher box the
shutter of visualization.
It is good then to have a
software which detects and cleans the PC of these undesirable.

will know to him that it has in him the protocol of a
virus. It will say to you that a new alternative of virus
arrived and it will remove it to you, according to the
parameters which you will have defined of course. Finally
the data processing specialists update the list of the
viral signatures at least every three hours. I do not
want to make them of pub, but I find that it is really

Be wary of the Flash files. A fault of safety exists in
the Flash readers of Macromedia on all the versions until
184.108.40.206. This fault is exploitable remote via any site
or via an enclosure and the attacks touch all the navigators.
It be-with saying that when a pirate sends a Flash animation
to you (extension .swf) and that it is read, he will be
able to open a footbridge between its computer and yours,
by a means of saturation of the buffer memory of the PC
(complicated Ca!). Seek the patch which corrects this
large bug, on the site of Macromedia.
