  • The person might have a computer virus infection when the computer start acting differently.For instance getting slow or when they turn on the computer it says that all the data are erased or something else abnormal has happened.
  • Malware is a general name for all programs that are harmful; viruses,trojan,worms and all other similar programs. Different Types of Malware Worms Trojan Viruses
  •  Viruses does not just appear, there is always somebody who has made it and they have own reason to so.Viruses are written everywhere in the world.  Most of the writers are young men.There are also few university students, professors, computer store managers, writers and even a doctor has written a virus.
  • Main mission of viruses is to spread out and then get active.Then it hack into user account and sent data to its owner or slow that machine.
  • A computer is infected with boot sector virus if it is booted from an infected disk.These viruses spread normally via floppy disks. 1 • Unsolicited demonstration disks 2 • Brand-new software 3 • Repaired hardware
  •  When viruses activate they do very different things.Might show abnormal text,format hard disk or do changes to files.  There is also talk that viruses have done something to hardware like hard disk.Viruses can not do any harm to hardware but they can do harm to programs and for example to BIOS so that computer does not start after that.
  • What are the signs of viruses  Almost anything odd a computer may do,can blamed on a computer "virus" especially if no other explanation can readily be found.  A computer virus can cause unusual screen displays, or messages - but most don't do that. A virus may slow the operation of a computer - but many times that doesn't happen. Even longer disk activity, or strange hardware behavior can be caused by legitimate software or harmless "prank" programs.
  • An Example Of Error Message Due To Virus
  • What to do when you find viruses  Make sure that it is virus and what virus it is.It is important to know what kind of virus you are dealing with.Companies that make anti-virus programs know what different viruses do and you can go to their web pages and read about the virus.  In some cases it is not good to start your computer from hard disk, because the virus may active and then do some harm.
  •  The best way to protect your computer is to use updated anti-virus program.  One can protect the computer against boot sector viruses by setting the BIOS to start from a hard disk rather than from a floppy disk.  Write protection is a good way to prohibit against viruses. Write protection works well in Windows NT and UNIX but not that well in Windows and Windows95.
  • There are three different kind of anti-viral packages: activity monitors, authentication or change-detection software, and scanners. Each type has its own strengths and weaknesses. Commercial anti-viral programs have a combination of the above mentioned functions.
