Trojan Horse, titled after the famous Greek myth, is used to describe a program that secretly disguises and actually looks like a legitimate program. It is a fake.
Computer viruses, worms, and Trojan horses are all classified as malicious-logic programs which are programs that deliberately harm a computer. Although these are the common three, there are many more variations.It would be almost impossible to list them all.
You know when a computer is infected by a virus, worm, or Trojan horse if one or more of these actions occur:
1 Screen shots of weird messages or pictures appear.
2 You have less available memory then you anticipated
3 Music or sounds plays randomly.
4 Files get corrupted
5 Program files don’t work properly
6 Unknown files or programs randomly appear
7 program properties fluctuate
Computer viruses, worms, and Trojan horses deliver their payload or details through three common ways.
One: When an individual runs a contaminated program. If you down load a lot of files, you should always scan the files before executing, especially executable files.
Second: When an individual boots a computer with an infected drive. That’s why it’s essential to not leave media files or programs in your computer when you shut it down.
Third: When a person connects an unprotected computer to a network.
Today, a very typical way to receive a computer virus, worm, or Trojan horse, is when you open an contaminated file through an email attachment.
There is no known method to completely protect a computer or computer network from computer viruses, worms, and Trojan horses, but individuals can take several precautions to significantly reduce chances of being infected by one of those malicious programs.
Whenever you start a computer equipment you should have no removable media in the drives. When the computer starts up, it tries to execute, perform a boot sector on the drives and even if unsuccessful, any given variable on the boot sector can infect the computer’s hard disk.
If you must start the computer for a particular reason, such as the hard disk fails and you are trying to reformat the drive, make sure that the disk is not corrupted.
