Viruses

When someone talks about a virus what i imidietly think it is that your computer was like "haked" or because you opend lets say a link or entered a page that has this virus then the people who create that virus can have do stuff in your computer including entering you email and just being in your stuff.

This topic brings alot of questions to myself. Some of those questions are..
-What can you do if your computer get a virus?
-How do to figure out that your computer has a virus?
-What can a virus do to your computer?
-Does the person that made the virus and it got into your computer see what you are doing and turn opn programs like your webcam so they can see you?

• "A computer virus is a small software program that spreads from one computer to another and interferes with computer operation. A computer virus might corrupt or delete data on a computer, use an email program to spread the virus to other computers, or even delete everything on the hard disk.Computer viruses are frequently spread by attachments in email messages or by instant messaging messages. Therefore, you must never open an email attachment unless you know who sent the message or you are expecting the email attachment. Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files. Computer viruses also spread through downloads on the Internet. They can be hidden in pirated software or in other files or programs that you might download."  this defenition i found it in this very reliable website

• In this website I could find out that its really important to keep getting updates of avoiding viruses or else its easier for the virus to have a newer software than the one your computer has. 

• In this website i could find out that its extremely important that you don't open emails from people you don't know, even if they are funny pictures or tempting stuff for you to open, that way is how the viruses get into your computers. Those viruses can not only be transmited by people you don't know but also is a person you do know can be haked and the email could be sent, so be careful if you are not expecting something and it arrives. 

• Trojans: "Trojan Horses, are additions to your system. These malicious programs masquerade as legitimate files in your email, deceiving you into willfully adding them to your hard drive. Trojans rely on you to intentionally open your computer to them. Once on your machine, Trojans then function as independent programs that operate secretly. Commonly, Trojans steal passwords or perform "denial of service" (overload your system) attacks." defenition was taken out of here. As you read about the trojans they are this additions that can damage and take alot of information private information you had. so try avoid getting those trojans. 

• Worms: "Internet Worms, are also unwanted additions to your system. Worms are different from Trojans, though, because they copy themselves without your direct assistance... they robotically worm their way into your email, and begin broadcasting copies of themselves without permission. Because they do not require user intervention to reproduce, worms reproduce at an alarming rate. Examples of worms include". this defentioin was also taken out of here. Worms as they call them and you read about them you can see that they work totally by their own way and damage alot of your stuff and can even spread viruses as they can work at a amazing speed.  

• In order to remove a virus you need to run an online scan, this scan will determine what virus you had and help you delete it, this will also delete your hard disk and hopefully help your computer run better. Also before you scan it you might want to follow this steps. website

• In order for you to know that you have a virus you are going to get several clues like:

          -your computer is running slow 

          - if you computer asks you for more memory card

          - if you get unexpected messages

          - programs start automatically without you ordering them to start 

          

so if you are getting some of those alerts make sure to check on programs like the scan we talked about before.  website

This topic is really important for our everyday lives because we live in a society that is full of technology and technology brings its bad things and you need to be careful to what you open what to do in the internet because viruses can then appear in your computer. Nobody wants to have a virus because that implicated alot of problems that can evolve and become really bad. so this is something we need to be extremely aware of. 

I still wonder if there are some viruses that dont give you c=any clues that they are there so you will never find out that they are there.
