Computer Security

  • Virus Protection is a Top Priority for students and/or faculty.
    • Don't wait to be hit by a virus, get a virus protection program.  Do this FIRST!
      • Be sure you have an up-to-dated virus protection program.
        Norton Anti virus is the one of the best programs.  It is inexpensive and can be
        obtained for about $15 to $39 from many stores including the following sites.

                              e. g. (WalMart or many other stores
                              have these programs for about $29 - 39.)
      • Do the live, online, update of virus definitions at least one time each week to
        protect yourself  and others you email from new viruses.
      • If you bought a new computer recently, it may have had a TEMPORARY virus program.
        Before it expires, get your own copy of virus protection as described above.  Don't wait!
  • Backup your computer data files each week on a floppy or zip disks.
    • Files can easily become corrupted or deleted by mistake or your hard drive may crash.
    • In other words, keep other copies of your important files stored in another place
       place other than your computer hard drive.  Don't forget to do this!!!!!
    • These might be all the files you have created with other programs such as
      word processing, spreadsheet, email files, Internet bookmarks or favorites,
      databases, other assignments, etc.
    • This is especially important if you do not have your own computer and you use
      one that belongs to someone else or in a lab.  Make more than one backup copy.
    • Carefully store your backup copies in a safe place
      • Away from telephones (watch your cell phone that it is not stored with backup diskettes)
      • Avoid excessive heat (Don't leave them in your car in the summer or lying in the sunshine)
      • Protect against liquids such as beverages and rain
      • Put in a place they will not be lost or stolen

Computer Maintenance you should periodically perform.

  • Scan Disk and Defrag your computer hard drive to detect and repair disk errors.
    • This increases speed and performance.
    • If you are using Microsoft Windows Operating system
      1. open "My Computer"
      2. Click once on the local disk you want to check  (usually drive C)
      3. Click on the "File" menu in the upper left corner of the screen
      4. Select "Properties."
      5. Click the "Tools" tab.

                        - Under Error-checking, click "Check Now."
                        - Under Check disk options select the Scan for and attempt recovery of bad
                          sectors check box.
                          This process will check for errors or bad sectors on your computer.
                        - All files should be closed for this process to run properly.
                        - Under Defragmentation, click "Defragment Now." Click "Defragment"
                           This may take a while. "Disk Defragmenter rearranges files, programs, and
                           unused space on
your computer's hard disk, so that programs run faster
                            and files open more quickly.
                         -
Disk Defragmenter will not hurt any of you files or programs.
