  • 5. How Computer Viruses Work: Computer viruses tend to grab our attention. On the one hand, viruses show us how vulnerable we are. A properly engineered virus can have an amazing effect on the worldwide Internet. On the other hand, they show how sophisticated and interconnected human beings have become.
  • 6. What are the signs of viruses: A computer virus can cause unusual screen displays, or messages - but most don't do that. A virus may slow the operation of the computer - but many times that doesn't happen. Even longer disk activity, or strange hardware behavior can be caused by legitimate software, harmless "prank" programs, or by hardware faults. A virus may cause a drive to be accessed unexpectedly and the drive light to go on but legitimate programs can do that also.
  • 7. Actions to prevent virus infection: - Always update your anti-virus software at least weekly. - Back up your important files and ensure that they can be restored. - Change the computer's boot sequence to always start the PC from its hard drive .
  • 8. Actions to prevent virus infection: -Don't share Drive C: without a password and without readonly restrictions. - Empty floppy drives of diskettes before turning on computers, especially laptops. - Get trained on your computer's anti-virus software and use it.
