    • The only irreplaceable element in a computer is user data

    • This is the files and folders created by the computer users

    • For this reason, it is imperative that the user data is protected.

    • This involves a number of strategies:

      • Backup

      • Anti Virus and Spyware protection


    Windows xp18

      • A hard disk partition other than the C: partition

      • A tape drive

  • The backup is created as a single file on the destination drive


  • Windows xp22

    Windows XP

    • Virus Protection

    • Malware is the term used to cover all types of computer contamination. Viruses and spyware are both malware

      • Viruses - A virus is a software program which enters a computer without the users knowledge.

        • A virus might attach itself to a program like a spreadsheet program

        • Each time the spreadsheet program runs, the virus runs, giving it the opportunity to enter memory and infect any other programs running on the computer

        • Viruses often carry a payload which is run when the virus is in memory and this can vary in severity up to totally erasing a disk


    Windows xp23

    Windows XP

    • Worms - a small piece of software that uses computer networks and security holes to replicate itself. It reads address books and emails itself to everyone in it

    • Trojan horses - a program that invites the user to run it, offering benefits, usually free of charge. Hidden in the program is malicious software, usually with a payload

    • Spyware - software which enters a computer without the users knowledge. Adware is a form of spyware which displays advertisements on the users computer. Some spyware monitors computer and internet use and reports back to the creator of the spyware. Some hijacks the internet connection and redirects the user to unwanted web sites

    • Spyware and viruses can cause a lot of disk and memory activity and as a result, seriously slow down a computer


    Windows xp24

    Windows XP

    • Virus and Spyware Precautions

      • Don’t open email attachments from unknown senders

      • Don’t openemail attachments unless you know exactly what it is, even if it appears to come from a friend or someone you know

      • Don’t openemail attachments if there is no subject or the subject text is unusual

      • Use cautionwhen downloading files from the Internet

      • Update your anti-virus software regularly

      • Install an effective firewall

      • Keep your spyware removal software up to date

      • Perform regular computer backups

      • If you have any doubt, err on the side of caution

      • Do not install ActiveX controls

      • Use the limited account for normal computer use and an administrator account for installing software etc


    Windows xp25
