A virus is a program


A virus is a program – a piece of executable code – that has the possibly of cloning itself. Computer viruses can spread fast and they are hard to eradicate. They can be attached to any type of file and they are spread as files copied and sent from person to person. They can be contacted from a floppy disk or Cd, they can be launched when opening a program or accessing a file, any file, or they can be brought from the internet by downloading a file or accessing a web page and as attachments to e-mails.

Besides replication, some viruses have something else in common: their infecting routine. The behaviors of viruses vary from showing messages or images to destroying files, formatting the hard disk drive and other severe damage. If the virus does not inflict damage it can still cause problems by taking up space and memory, lowering the performances of the computer.

Nine rules for avoiding viruses would be:
  1. Use an anti virus program at all times.
  2. Install and keep active a firewall.
  3. Make sure your system is up-to-date with all the existent updates.
  4. Keep your browsers security settings at maximum.
  5. Never click yes when your browser asks you if you want to install or open some content coming from an organization you don’t know or don’t trust.
  6. Install an anti-spy ware program to enlarge the protection.
  7. 7. Never install a browser help or search bar accepting the times it comes from a reliable source.
  8. 8. Use a different credit card for online shopping.
  9. 9. Don’t click on email attachments that are executable files even if they look as if sent from known persons.
The antivirus programs have a big role in providing your computers security and protecting it from viruses, worms, Trojan horses and other “invaders” that can attack a computer. The role of an antivirus program is to detect the presence of viruses in a computer, to disinfect the files or delete the ones that can’t be disinfected and prevent the contamination of the computer.

Most of the companies that produce antivirus have online free tools for scanning computers for viruses. If you don’t have an antivirus yet and can’t decide which one to buy you can enter their online sites and try the services for free, then decide what to use.

or playing with the food, express yourself clearly as if you are the one that has a problem.

”What did you really mean by that?”

When kids fight and get nervous, it is possible for them to say things like “I hate you”. but that doesn’t have to scare you because these are the first words that come to mind when they are engaged in a conflict with their friends. But you can help them get over it and make them think of what was it that made them so nervous and angry.

”People are different and they have different needs.”

When you here you child say for the thousandth time “But this is not fair”, you have to make them understand that the reason that makes people be treated differently is the fact they have different needs.
