Computer Viruses The Basics

Computer Viruses The Basics



Computer Viruses - the​ basics
In its simplest terms a​ virus is​ a​ disruptive computer code period!
a​ computer virus almost always repeats itself and spreads by attaching itself to​ other files .​
Viruses can be made to​ host a​ number of​ harmful things on​ any computer from disrupting files to​ crashing networks .​
It can even be laying dormant,​ without you knowing it's there and then attack when least expect it,​ like right in​ the​ middle of​ downloading a​ large file or​ typing a​ long report.
It can even be made to​ open at​ a​ certain date,​ sitting like a​ timebomb until it's time arrives .​
As you can see it​ can be annoying at​ the​ very least.
I​ do not want go into all the​ different types of​ viruses here because there are so many and more are being made everyday in​ some dank basement by the​ Dark Lord.
However,​ since so many viruses came from unknowingly opening e-mails I​ would like to​ mention some basics here:
Never open e-mail attachments unless you know for sure who it's from and that it's safe.
Some mail programs will even ask if​ you trust the​ attachment and if​ you’re sure this you want to​ do .​
Your computer software can also scan attachments for viruses.
the​ danger is​ that when the​ attachment is​ opened the​ virus can attach itself to​ your hard drive and damage files .​
Not only that,​ it​ can search your saved e-mail addresses and send itself out to​ your friends,​ business partners and whoever is​ on​ the​ list,​ masking the​ message to​ look like a​ legitimate one from you .​
It will probably have an​ attachment too and when opened will infect other computers.
Many people like to​ download music,​ video,​ games or​ other programs from different sites .​
If it​ is​ a​ site you dealt with before and trust it​ may be safe ok,​ but if​ you’re not sure you can always run a​ virus scan on​ the​ download before installation .​
(You will need to​ check the​ anti-virus program that came with your system on​ procedures) .​
This security measure is​ necessary because some downloads may contain virtues,​ spyware or​ adware – these last two can collect personal information,​ note your browsing habits and spam your e-mail with unwanted ads .​
Some software sites will offer a​ readme file that shows technical information on​ the​ download (if you like tech talk) as​ well as​ contact info.
The better sites that offer downloads will test and scan all there software programs before going online with it .​
As a​ last resort you can do an​ internet search for reviews on​ that particular company to​ see if​ others got burned.
This may sound scary to​ some but the​ fact is​ in​ this world anyone who owns a​ computer will have to​ look over there shoulders for hidden attacks when working with online .​
That said there are some things should do to​ prevent viruses from attacking your computer:
* Download the​ latest virus definition lists ( files that tell your computer what to​ scan for) that's used for your anti-virus program.
* Check to​ see if​ your internet service provider has tools to​ stop viruses before they can reach your mailbox.
* Always back-up your computer on​ CD-R disks or​ other media in​ case you loose some or​ all your data.
* You can scan software for viruses before installing it .​
(See system manual for procedure)
* Set your security settings at​ the​ highest level.
* Check your web browser and e-mail settings.
Doing these things at​ least every week will help keep your computer up to​ date on​ Virus protection and running safely.
