There is a continuous development of computers and intent technologies but in the mean time all these developments  on one side leads to the development  in the various fields  for example  education , communication and  business, but  on the other  side it caused several  threats  on the Internet such as virus, trojan horse, worm, and spyware .But before discussing on the process to get rid of these  threats, we need to understand what exactly these threats are and how they spreads.A virus is a program or code that copies itself into other programs, it execute itself and replicate itself. Virus can infect desktop and network server, some viruses are programmed to damage the computer by damaging programs deleting files or reformatting the hard disk. Others are not designed to do any damage, but simply to replicate themselves and make their presence in video, and audio messages. These viruses can create problems for the computer user. They take computer memory used by important programs, these viruses can crash your system and slow your computer or even some times freezes the computer . Viruses are of many kind and they infected different files like file infector viruses. These viruses normally infects executable code, such as .exe and .dll  files. They can infect other  files when an infected program is copied  from floppy, hard drive or from the network . Boot sector viruses infect the boot record on floppy disks and hard disks. All floppy disks and hard disks  contain a small program in the boot record that is run when the computer starts up. Boot sector viruses to this part of the disk and activate when the user attempts to start up from the infected disk these viruses responsible for slow booting of your computer. Master boot record Master boot record viruses are memory-resident viruses that infect disks in the same manner as boot sector viruses. To repair computer infected by virus you need antivirus.Worms are almost similar to that of the virus. Unlike the viruses, worm uses computer networks to replicate itself.  It searches for servers with security holes and copies itself .Worms are programs that replicate themselves from system to system without the user. This is in contrast to viruses which requires the spreading of an infected host file, However worms generally exist inside of other files often Word or Excel documents, there is a difference between how worms and viruses use the host file. To remove all these threats from our computer, we need to download and install antivirus software on our computer.
